VPH_PWR is routed to battery, so it is not configurable. However few
devices, e.g. WM5110 expect speaker power supplies, thus provide the
regulator for full hardware description. Audio amplifier also accepts
that power supply.

According to s3fwrn5 driver code the "enable" GPIO line is driven "high"
when chip is not in use (mode is S3FWRN5_MODE_COLD), and is driven "low"
when chip is in use.
s3fwrn5_phy_power_ctrl():
...
gpio_set_value(phy->gpio_en, 1);
...
if (mode != S3FWRN5_MODE_COLD) {
msleep(S3FWRN5_EN_WAIT_TIME);
gpio_set_value(phy->gpio_en, 0);
msleep(S3FWRN5_EN_WAIT_TIME);
}
Therefore the line described by "en-gpios" property should be annotated
as "active low".
The wakeup gpio appears to have correct polarity (active high).

Universal Serial Interface (USI) supports three types of serial interface
such as Universal Asynchronous Receiver and Transmitter (UART), Serial
Peripheral Interface (SPI), and Inter-Integrated Circuit (I2C).
Each protocols can be working independently and configured as one of
those using external configuration inputs.
Exynos Auto v9 SoC support 12 USIs. When a USI uses two pins such as i2c
and 3 wire uarts(RX/TX only), we can use remain two pins as i2c mode.
So, we can define one USI node that includes serial/spi and hsi2c.
usi_i2c nodes can be used only for i2c mode.
We can have below combinations for one USI.
1) The usi node is used either 4 pin uart or 4 pin spi
-> No usi_i2c can be used
2) The usi node is used 2 pin uart(RX/TX) and i2c(SDA/SCL)
-> usi_i2c should be enabled to use the latter i2c
3) The usi node is used i2c(SDA/SCL) and i2c(SDA/SCL)
-> usi_i2c should be enabled to use the latter i2c
By default, all USIs are initially set to uart mode by below setting.
samsung,mode = <USI_V2_UART>;
You can change it either USI_V2_SPI or USI_V2_I2C.

The DTS uses hardware register values directly in pin controller pin
configuration. These are not some IDs or other abstraction layer but
raw numbers used in the registers.
These numbers were previously put in the bindings header to avoid code
duplication and to provide some context meaning (name), but they do not
fit the purpose of bindings.
Store the constants in a header next to DTS and use them instead of
bindings.

The pl330 DMA controller provides number of DMA channels and requests
through its registers, so duplicating this information (with a chance of
mistakes) in DTS is pointless. Additionally the DTS used always wrong
property names which causes DT schema check failures - the bindings
documented 'dma-channels' and 'dma-requests' properties without leading
hash sign.

Conversion of Samsung pinctrl bindings to dtschema followed up with
alignment of DTS files to the dtschema.
The entire work consists of three parts but everything should be merged
at once to avoid dtschema check errors:
1. Samsung pinctrl driver change necessary to accept new DTS (driver
depends on node names and this has to be adjusted because of dtschema).
2. Conversion to dtschema which brings requirement of different naming
of the GPIO nodes.
3. DTS commits depending on driver (1) above, which convert all GPIO pin
bank names to new naming, required by dtschema.
This also includes few cleanups around DTS which are here to avoid
any merge conflicts.
The Samsung pinctrl driver changes are backwards compatible. However
the DTS changes (renaming nodes) could cause problems in out-of-tree or
other project implementations of the driver.

Older Samsung Exynos SoC pin controller nodes (Exynos3250, Exynos4,
Exynos5, Exynos5433) with external wake-up interrupts, expected to have
one interrupt for multiplexing these wake-up interrupts. Also they
expected to have exactly one pin controller capable of external wake-up
interrupts.
It seems however that newer ARMv8 Exynos SoC like Exynos850 and
ExynosAutov9 have differences:
1. No multiplexed external wake-up interrupt, only direct,
2. More than one pin controller capable of external wake-up interrupts.
Use dedicated Exynos850 compatible for its external wake-up interrupts
controller to indicate the differences.

The pin controller device node is expected to have one (optional)
interrupt. Its pin banks capable of external interrupts, should define
interrupts for each pin, unless a muxed interrupt is used.
Exynos850 defined the second part - interrupt for each pin in wake-up
pin controller - but also added these interrupts in main device node,
which is not correct.

* Octa cores (Cortex-A55), supporting PSCI v1.0
* ARM architected timer (armv8-timer)
* Interrupt controller (GIC-400)
* Pinctrl nodes for GPIO
* Serial node
Basic platform features:
* Clock controller CMUs
* OSCCLK clock
* MCT timer
* ARM PMU (Performance Monitor Unit)
* Chip-id
* RTC
* Reset
* Watchdog timers
* eMMC
* I2C
* HSI2C
* USI
All those features are tested on E850-96 board with minimal BusyBox
rootfs.

Add required voltage regulators for USB DWC3 block on Exynos7 Espresso
board. Due to lack of schematics of Espresso board, the choice of
regulators is approximate. What bindings call VDD10, for Exynos7 should
be actually called VDD09 (0.9 V). Use regulators with a matching
voltage range based on vendor sources for Meizu Pro 5 M576 handset (also
with Exynos7420).

As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms.
All the newly supported SoCs belong into existing families
this time:
- Qualcomm gets support for two newly announced platforms, both
of which can now work in production environments: the SDX65
5G modem that can run a minimal Linux on its Cortex-A7 core,
and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3
family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread
i.MX8 series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
we have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
while MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two
new SoCs, plus a number of Chromebook variants and phones based
on the Snapdragon 7c, 845 and 888 SoCs, including various
Sony Xperia devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit
chips out of the box, including a number of ASUS Transformer
tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max

According to USI v2 driver change[1], serial_0 node should be converted to
use the USI node hierarchy. syscon_peric0 will be used as a syscon node
to control the USI00_USI_SW_CONF register.
This also changes the serial node name from uart@ to serial@.

In Device Tree specification it's recommended to use "i2c" name for I2C
nodes. Now that i2c-exynos5 dt-schema binding was added, it shows some
warnings like this when validating HS-I2C nodes:
hsi2c@xxxxxxxxx: $nodename:0: 'hsi2c@xxxxxxxx' does not match

It's not possible to reboot or poweroff Exynos7420 using PSCI. Instead
we need to use syscon reboot/poweroff drivers, like it's done for other
Exynos SoCs. This was confirmed by checking vendor source and testing it
on Samsung Galaxy S6 device based on this SoC.
To be able to use custom restart/poweroff handlers instead of PSCI
functions, we need to correct psci compatible. This also requires us to
provide function ids for CPU_ON and CPU_OFF.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"

"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked

with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in

Commit ef72171b36 ("arm64: dts: exynos: Remove unneeded address space
mapping for soc node") changed the address and size cells in root node from
2 to 1, but /memory nodes for the affected boards were not updated. This
went unnoticed on Exynos5433-based TM2(e) boards, because they use u-boot,
which updates /memory node to the correct values. On the other hand, the
mentioned commit broke boot on Exynos7-based Espresso board, which
bootloader doesn't touch /memory node at all.
This patch reverts commit ef72171b36 ("arm64: dts: exynos: Remove

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.
Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.
Update cooling maps to include all devices affected by individual trip
points.

As always, a large number of DT updates. Too many to enumerate them all,
but at a glance:
New SoCs introduced in this release:
- Amlogic:
+ Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some set
top boxes and other products.
- Mediatek:
+ MT7623A, which is a flavor of the MT7623 family with other on-chip
ethernet options.
- Qualcomm:
+ SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845
(Cortex-A75/A55 derivative) SoC that's one of the current high-end
mobile SoCs.
It's great to see mainline support for it. So far, you
can't do much with it, since a lot of peripherals are not yet in the
DTs but driver support for USB, GPU and other pieces are starting to
trickle in. This might end up being a well-supported SoC upstream if
the momentum keeps up.
- Renesas:
+ R8A77990, a.k.a R-Car E3, a new automotive entertainment-targeted
SoC. Currently only one Cortex-A53 CPU is enabled, we are eagerly
awaiting more. So far, basic drivers such as serial, gpios, PMU and
ethernet are enabled.
+ R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR
GPU. Same here, basic set of drivers such as serial, gpios and ethernet
enabled, and SMP support is also forthcoming.
- STMicroelectronics:
+ STM32F469, very similar tih STM32F429 but with display support
Enhancements to SoCs/platforms (DTS contents, some driver portions might
not be in yet):
- Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc
- Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets

If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each
DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from
the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile.
It could be a race problem when building DTBS in parallel.
Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor
sub-directories, so this broke when Broadcom added one more hierarchy
in arch/arm64/boot/dts/broadcom/<soc>/.
One idea to fix the issues in a clean way is to move DTB handling
to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y
natively, so it should not hurt to do so.
Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is
enabled. All clutter things in Makefiles go away.
As a bonus clean-up, I also removed dts-dirs. Just use subdir-y
directly to traverse sub-directories.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

Add initial clock configuration for display subsystem for Exynos5433
based TM2/TM2e boards in device tree in order to avoid dependency on the
configuration left by the bootloader. This initial configuration is also
needed to ensure that display subsystem is operational if display power
domain gets turned off before clock controller is probed and the inital
clock configuration left by the bootloader saved.
TM2 and TM2e uses different rate for DISP PLL clock, but for better
maintainability all 'assigned-clocks-*' properties for DISP CMU are
defines in each board dts instead of redefining the rates property.

Currently TM2E dts includes TM2 but there are some differences
between the two boards and TM2 has some properties that TM2E
doesn't have.
That's why it's important to keep the two dts files independent
and put all the commonalities in a tm2-common.dtsi file.
At the current status the only two differences between the two
dts files (besides the board name) are ldo31 and ldo38.
