118f3fbe51 dt-bindings: mtd: partitions: support label/name only partition
Document new partition nodes that declare only the label/name instead
of the reg used to provide an OF node for partition registred at runtime
by parsers. This is required for nvmem system to declare and detect
nvmem-cells.

With these special partitions, the reg / offset is not required and a
'partition-' prefix is needed.
The node name with the 'partition-' prefix stripped, is used to match
the partition allocated by the parser at runtime and the parser will
provide reg and offset of the mtd.
If the partition to match contains invalid char for a node name, the
label binding can be used to declare the partition name.

NVMEM will use the data from the parser and provide the NVMEM cells
declared in the DTS, "connecting" the dynamic partition with a
static declaration of cells in them.

5278cc93a9 dt-bindings: mtd: qcom_nandc: document qcom,boot-partitions binding
Document new qcom,boot-partition binding used to apply special
read/write layout to boot partitions.

QCOM apply a special layout where spare data is not protected
by ECC for some special pages (used for boot partition). Add
Documentation on how to declare these special pages.

99c1734f31 dt-bindings: mtd: mxc-nand: Drop undocumented properties from example
With unevaluatedProperties issues fixed, 'nand-bus-width' and
'nand-ecc-mode' are flagged as undocumented. Removing them from the example
is the easiest solution to silence the warnings.

987cf300e7 dt-bindings: mtd: spi-nand: Add spi-peripheral-props.yaml reference
SPI peripheral device bindings need to reference spi-peripheral-props.yaml
in order to use various SPI controller specific properties. Otherwise,
the unevaluatedProperties check will reject any controller specific
properties.

e1dff7f133 dt-bindings: memory-controllers: ingenic: Split out child node properties
Binding schemas which define child node properties such as memory
controllers with timing properties need a separate schema which can be
referenced from child device schemas. This is necessary for
unevaluatedProperties checks to work properly.

Move the ingenic,nemc child properties to its own file and reference
from ingenic,nand.yaml which describes a child NAND controller.

d8e0f976f1 spi: Updates for v5.19
This is quite a quiet release but some new drivers mean that the
 diffstat is fairly large, the new drivers include the aspeed driver
 which is migrated from MTD as part of the ongoing move of controllers
 with specialised support for SPI flashes into the SPI subsystem.
 
  - Support for devices which flip CPHA during recieve only transfers
    (eg, if MOSI and MISO have inverted polarity).
  - Overhaul of the i.MX driver, including the addition of PIO support
    for better performance on small transfers.
  - Migration of the Aspeed driver from MTD.
  - Support for Aspeed AST2400, Ingenic JZ4775 and X1/2000 and MediaTek
    IPM and SFI.

caf83e494d dt-bindings: Drop redundant 'maxItems/minItems' in if/then schemas
Another round of removing redundant minItems/maxItems when 'items' list is
specified. This time it is in if/then schemas as the meta-schema was
failing to check this case.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

- Add Krzysztof Kozlowski as co-maintainer for DT bindings providing

 - DT schema validation now takes DTB files as input rather than
   intermediate YAML files. This decouples the validation from the source
   level syntax information. There's a bunch of schema fixes as a result
   of switching to DTB based validation which exposed some errors
   and incomplete schemas and examples.
 
 - Kbuild improvements to explicitly warn users running 'make
   dt_binding_check' on missing yamllint
 
 - Expand DT_SCHEMA_FILES kbuild variable to take just a partial filename
   or path instead of the full path to 1 file.
 
 - Convert various bindings to schema format: mscc,vsc7514-switch,
   multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS
   bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel
   SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display
   subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma,
   msm/mdp4, rda,8810pl-uart
 
 - New schemas for u-boot environment variable partition, TI clksel
 
 - New compatible strings for Renesas RZ/V2L SoC
 
 - Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated HiSilicon
 
 - Add/fix schemas for QEMU Arm 'virt' machine
 
 - Drop unused of_alias_get_alias_list() function
 
 - Add a script to check DT unittest EXPECT message output. Pass messages
   also now print by default at PR_INFO level to help test automation.

dca669354e dt-bindings: Another pass removing cases of 'allOf' containing a '$ref'
Another pass at removing unnecessary use of 'allOf' with a '$ref'.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords.

dt-bindings: mtd: spi-nor: Allow two CS per device
The Xilinx QSPI controller has two advanced modes which allow the
controller to behave differently and consider two flashes as one single
storage.

One of these two modes is quite complex to support from a binding point
of view and is the dual parallel memories. In this mode, each byte of
data is stored in both devices: the even bits in one, the odd bits in
the other. The split is automatically handled by the QSPI controller and
is transparent for the user.

The other mode is simpler to support, it is called dual stacked
memories. The controller shares the same SPI bus but each of the devices
contain half of the data. Once in this mode, the controller does not
follow CS requests but instead internally wires the two CS levels with
the value of the most significant address bit.

Supporting these two modes will involve core changes which include the
possibility of providing two CS for a single SPI device

The flash on the DNS-313 needs to be probed as JEDEC, it does not conform to the common CFI standard.

dt-bindings: mtd: spi-nor: Add a reference to spi-peripheral-props.yaml
The spi-peripheral-props.yaml schema contains peripheral-specific
properties for SPI controllers that should be present in the peripheral
node. Add a reference to that so its constraints are followed.

additionalProperties: false cannot be used since it marks the controller
properties as unknown. Use unevaluatedProperties: false instead. This
has the side effect of allowing extra properties that are not specified
in the schema. The alternative is to list all the controller properties
in this schema but that would mean every peripheral binding would have
to repeat the same set of properties for each controller.

778cb8e39f dt-bindings: mtd: gpmc: Fix the ECC bytes vs. OOB bytes equation
"PAGESIZE / 512" is the number of ECC chunks.
"ECC_BYTES" is the number of bytes needed to store a single ECC code.
"2" is the space reserved by the bad block marker.

"2 + (PAGESIZE / 512) * ECC_BYTES" should of course be lower or equal
than the total number of OOB bytes, otherwise it won't fit.

Fix the equation by substituting s/>=/<=/.

e8917266ae dt-bindings: More dropping redundant minItems/maxItems
Another round of removing redundant minItems/maxItems from new schema in
the recent merge window.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

6b562738a2 dt-binding: mtd: nand: Document the cs-gpios property
To reach higher capacities, arrays of chips are now pretty common.
Unfortunately, most of the controllers have been designed a decade ago
and did not all anticipate the need for several chip-selects. The new
cs-gpios property allows to workaround this limitation by adding as many
GPIO chip-select as needed.

27736ddd24 dt-bindings: mtd: brcmnand: convert to the json-schema
This helps validating DTS files.

Changes that require mentioning:
1. Property "clock" was renamed to "clocks"
2. Duplicated properties (defined in nand-controller.yaml) were dropped
3. Compatible "brcm,nand-bcm63168" was added
4. SoC specific "compatible" cases got limited controller versions

Examples changes:
1. Nodes "nand" were renamed to "nand-controller"
2. Nodes "nandcs" were renamed to "nand"
3. Dropped partitions as they were using old syntax and are well
   documented elsewhere anyway

This rewritten binding validates cleanly using the "dt_binding_check".
Some Linux stored DTS files will require updating to make "dtbs_check"
happy.

ee590106c3 dt-bindings: mtd: Add a property to declare secure regions in NAND chips
On a typical end product, a vendor may choose to secure some regions in
the NAND memory which are supposed to stay intact between FW upgrades.
The access to those regions will be blocked by a secure element like
Trustzone. So the normal world software like Linux kernel should not
touch these regions (including reading).

So let's add a property for declaring such secure regions so that the
drivers can skip touching them.

a2590d6989 spi: Updates for v5.12
The main focus of this release from a framework point of view has been
 spi-mem where we've acquired support for a few new hardware features
 which enable better performance on suitable hardware.  Otherwise mostly
 thanks to Arnd's cleanup efforts on old platforms we've removed several
 obsolete drivers which just about balance out the newer drivers we've
 added this cycle.
 
  - Allow drivers to flag if they are unidirectional.
  - Support for DTR mode and hardware acceleration of dummy cycles in spi-mem.
  - Support for Allwinder H616, Intel Lightning Mountain, nVidia Tegra
    QuadSPI, Realtek RTL838x and RTL839x.
  - Removal of obsolute EFM32, Txx9 and SIRF Prima and Atlas drivers.

3ff9ee2a88 dt-bindings: mtd: spi-nor: Convert to DT schema format
Convert the SPI-NOR binding to DT schema format. Like other memory chips,
the compatible strings are a mess with vendor prefixes not being used
consistently and some compatibles not documented. The resulting schema
passes on 'compatible' checks for most in tree users with the exception
of some oddballs.

I dropped the 'm25p.*-nonjedec' compatible strings as these don't appear
to be used anywhere.

This standardizes its documentation, allows validating with Makefile
checks and helps writing DTS files.

Noticeable changes:
1. Dropped "Partitions can be represented by sub-nodes of a flash
   device." as we also support subpartitions (don't have to be part of
   flash device node)
2. Dropped "to Linux" as bindings are meant to be os agnostic.

This property does not describe very well its purpose: it describes
the ECC engine type. Deprecate it in favor of nand-ecc-engine which
points to either the NAND part itself in case of on-die ECC, or to the
parent node in case of an integrated ECC engine in the NAND controller
(previously referred as "hardware") or to another node in case of an
external controller. Other "modes" (none/software) are achieved with
the new nand-use-soft-ecc-engine and nand-no-ecc-engine properties.

6fdc6e23a7 dt-bindings: Add missing 'unevaluatedProperties'
This doesn't yet do anything in the tools, but make it explicit so we can
check either 'unevaluatedProperties' or 'additionalProperties' is present
in schemas.

'unevaluatedProperties' is appropriate when including another schema (via
'$ref') and all possible properties and/or child nodes are not
explicitly listed in the schema with the '$ref'.

This is in preparation to add a meta-schema to check for missing
'unevaluatedProperties' or 'additionalProperties'. This has been a
constant source of review issues.

b440915af2 dt-bindings: mtd: Document boolean NAND ECC properties
Document nand-use-soft-ecc-engine and nand-no-ecc-engine properties.
The former is here to force software correction, the latter prevents
any correction to happen.

These properties (along with nand-ecc-engine) are supposed to be more
accurate than the current nand-ecc-modes wich is very misleading and
very often people think it is mandatory while the core should be
relied upon to decide which correction to handle.

nand-ecc-mode was already inacurate, but it becomes totally
problematic with setups where there are several hardware engines.

This optional property defines where the ECC bytes are expected to be

locations can be explicitly set to OOB or interleaved depending if
the ECC bytes are entirely stored in the OOB area or mixed with
regular data in the main area (also sometimes referred as

c13ac55525 mtd: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

bce49d1e3c dt-bindings: mtd: update STM32 FMC2 NAND controller documentation
These bindings can be used on SOCs where the FMC2 NAND controller is
in standalone. In case that the FMC2 embeds 2 controllers (an external
bus controller and a raw NAND controller), the register base address,
the clock and the reset will be defined in the parent node.

0db958b689 dt-bindings: Fix more incorrect 'reg' property sizes in examples
The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to 1 cell
for address and size.

3d21a46093 dt-bindings: Remove cases of 'allOf' containing a '$ref'
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

dt-bindings: convert mtk-quadspi binding doc for spi-mtk-nor
spi-mtk-nor is a driver to replace mtk-quadspi and they have almost
the same device-tree bindings. Reuse this binding documentation and
convert it for new driver:

1. "Mediatek SoCs" -> "Mediatek ARM SoCs" because MTK MIPS SoCs
   use different controllers.
2. document "interrupts" as a required property because it's
   available on all SoCs with this controller and new driver takes
   advantages of it. It's implemented as optional only to maintain
   backward compatibility.
3. add a dummy interrupt binding in example.

Masahiro Yamada
48aad493e3 dt-bindings: mtd: denali_dt: document reset property
According to the Denali NAND Flash Memory Controller User's Guide,
this IP has two reset signals.

  rst_n:     reset most of FFs in the controller core
  reg_rst_n: reset all FFs in the register interface, and in the
             initialization sequencer

This commit specifies these reset signals.

It is possible to control them separately from the IP point of view
although they might be often tied up together in actual SoC integration.

At least for the upstream platforms, Altera/Intel SOCFPGA and Socionext
UniPhier, the reset controller seems to provide only 1-bit control for
the NAND controller. If it is the case, the resets property should
reference to the same phandles for "nand" and "reg" resets, like this:

    resets = <&nand_rst>, <&nand_rst>;
    reset-names = "nand", "reg";

15ffef1ae6 dt-bindings: Ensure child nodes are of type 'object'
Properties which are child node definitions need to have an explict
type. Otherwise, a matching (DT) property can silently match when an
error is desired. Fix this up tree-wide. Once this is fixed, the
meta-schema will enforce this on any child node definitions.

d8e8fd0ebf mtd: rawnand: denali: decouple controller and NAND chips
Currently, this driver sticks to the legacy NAND model because it was
upstreamed before commit 2d472aba15 ("mtd: nand: document the NAND
controller/NAND chip DT representation"). However, relying on the
dummy_controller is already deprecated.

Switch over to the new controller/chip representation.

The struct denali_nand_info has been split into denali_controller
and denali_chip, to contain the controller data, per-chip data,
respectively.

One problem is, this commit changes the DT binding. So, as always,
the backward compatibility must be taken into consideration.

In the new binding, the controller node expects

  #address-cells = <1>;
  #size-cells = <0>;

... since the child nodes represent NAND chips.

In the old binding, the controller node may have subnodes, but they
are MTD partitions.

The denali_dt_is_legacy_binding() exploits it to distinguish old/new
platforms.

Going forward, the old binding is only allowed for existing DT files.
I updated the binding document.

0051db8218 spi: Updates for v4.21
The main thing this release has been a lot of work on the integration
 with SPI NOR flashes, there's been some specific support for a while for
 controller features designed to make them perform better but it's not
 worked out as well as hoped so the interface has been redesigned in a
 way that will hopefully do better - it's already been adopted by a
 number of additional controllers so things are looking good.  Otherwise
 most of the work has been driver specific:
 
  - Support for better integration with NOR flashes from Boris Brezillon
    and Yogesh Narayan Gaur plus usage of it in several drivers.
  - A big cleanup of the Rockchip driver from Emil Renner Berthing.
  - Lots of performance improvements for bcm2835 from Lukas Wunner.
  - Slave mode support for pxa2xx from Lubomir Rintel.
  - Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,

Pull spi updates from Mark Brown:
 "The main thing this release has been a lot of work on the integration
  with SPI NOR flashes, there's been some specific support for a while
  for controller features designed to make them perform better but it's
  not worked out as well as hoped so the interface has been redesigned
  in a way that will hopefully do better - it's already been adopted by
  a number of additional controllers so things are looking good.

  Otherwise most of the work has been driver specific:

   - Support for better integration with NOR flashes from Boris
     Brezillon and Yogesh Narayan Gaur plus usage of it in several
     drivers.

   - A big cleanup of the Rockchip driver from Emil Renner Berthing.

   - Lots of performance improvements for bcm2835 from Lukas Wunner.

   - Slave mode support for pxa2xx from Lubomir Rintel.

   - Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,
     and Renesas r8a77470"

bb276262e8 mtd: spi-nor: only apply reset hacks to broken hardware
Commit 59b356ffd0 ("mtd: m25p80: restore the status of SPI flash when
exiting") is the latest from a long history of attempts to add reboot
handling to handle stateful addressing modes on SPI flash. Some prior
mostly-related discussions:

http://lists.infradead.org/pipermail/linux-mtd/2013-March/046343.html
[PATCH 1/3] mtd: m25p80: utilize dedicated 4-byte addressing commands

http://lists.infradead.org/pipermail/barebox/2014-September/020682.html
[RFC] MTD m25p80 3-byte addressing and boot problem

http://lists.infradead.org/pipermail/linux-mtd/2015-February/057683.html
[PATCH 2/2] m25p80: if supported put chip to deep power down if not used

Previously, attempts to add reboot-time software reset handling were
rejected, but the latest attempt was not.

Quick summary of the problem:
Some systems (e.g., boot ROM or bootloader) assume that they can read
initial boot code from their SPI flash using 3-byte addressing. If the
flash is left in 4-byte mode after reset, these systems won't boot. The
above patch provided a shutdown/remove hook to attempt to reset the
addressing mode before we reboot. Notably, this patch misses out on
huge classes of unexpected reboots (e.g., crashes, watchdog resets).

Unfortunately, it is essentially impossible to solve this problem 100%:
if your system doesn't know how to reset the SPI flash to power-on
defaults at initialization time, no amount of software can really rescue
you -- there will always be a chance of some unexpected reset that
leaves your flash in an addressing mode that your boot sequence didn't
expect.

While it is not directly harmful to perform hacks like the
aforementioned commit on all 4-byte addressing flash, a
properly-designed system should not need the hack -- and in fact,
providing this hack may mask the fact that a given system is indeed
broken. So this patch attempts to apply this unsound hack more narrowly,
providing a strong suggestion to developers and system designers that
this is truly a hack. With luck, system designers can catch their errors
early on in their development cycle, rather than applying this hack long
term. But apparently enough systems are out in the wild that we still
have to provide this hack.

Document a new device tree property to denote systems that do not have a
proper hardware (or software) reset mechanism, and apply the hack (with
a loud warning) only in this case.

791d3ef2e1 dt-bindings: remove 'interrupt-parent' from bindings
'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

d2ad00eb78 dt-bindings: mtd: explicitly document nesting partitions descriptions
Documentation was already saying that fixed and dynamic partitioning can
be mixed but was missing a clear description and examples. This commit
adds a proper documentation of how descriptions can be nested and how
layouts can be mixed.

This addition is important for partitions that contain subpartitions.
In such cases partitions have to be properly described in order to let
system handle them correctly.

Depending on situation, nesting descriptions may provide more accurate
logic/structure and/or allow mixing partitioning types (various
"compatible" values).

d91e8a3eec dt-binding: mtd: denali_dt: document clock property
Commit 30f9f2fb7b ("mtd: denali: add a DT driver") supported the
clock enablement, but did not document it in the DT binding.

In addition to the existing clock, this commit adds more clocks based
on the IP specification.

According to the Denali User's Guide, this IP needs three clocks:

 - clk: controller core clock

 - clk_x: bus interface clock

 - ecc_clk: clock at which ECC circuitry is run

The driver should accept the current single clock for the backward
compatibility, but the DT binding should represent the real hardware,
and future platforms must follow this.

None of the existing platforms connect the R/B pin to a GPIO (they all
use one of the dedicated R/B pin).
Anyway, if we ever get short of native R/B pins, it's probably better
to fallback to STATUS reg polling than trying to poll a GPIO.

Merge tag 'devicetree-for-4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:

 - Convert to use memblock_virt_alloc in DT code which supports
   bootmem arches. With this we can remove the arch specific
   early_init_dt_alloc_memory_arch() functions.

 - Enable running the DT unittests on UML

 - Use SPDX license tags on DT files

 - Fix early FDT kconfig ifdef logic

 - Clean-up unittest Makefile

 - Fix function comment for of_irq_parse_raw

 - Add missing documentation for linux,initrd-{start,end} properties

 - Clean-up of binding examples using uppercase hex

 - Add trivial devices W83773G and Infineon TLV493D-A1B6

 - Add missing STM32 SoC bindings

 - Various small binding doc fixes

Document the legacy and the new bindings for Marvell NAND controller.

The pxa3xx_nand.c driver does only support legacy bindings, which are
incomplete and inaccurate. A rework of this controller (called
marvell_nand.c) does support both.
