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.

In this particular location additionalProperties actually declares a property
named `additionalProperties` instead of specifying there should be no other
properties.

There's several cases of json-schema 'additionalProperties' at the wrong
indentation level which has the effect of making them DT properties. This
is harmless, but let's fix them so a meta-schema check for this can be
added.
In all the cases, either the 'additionalProperties' was extra or doesn't
work because there's a $ref to more properties. In the latter case, we
can use 'unevaluatedProperties' instead.

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.
Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.
So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

Convert ROHM bd71837 and bd71847 PMIC binding text docs to yaml. Split
the binding document to two separate documents (own documents for BD71837
and BD71847) as they have different amount of regulators. This way we can
better enforce the node name check for regulators. ROHM is also providing
BD71850 - which is almost identical to BD71847 - main difference is some
initial regulator states. The BD71850 can be driven by same driver and it
has same buck/LDO setup as BD71847 - add it to BD71847 binding document and
introduce compatible for it.

is determined by the I2C control.
2.For MP8867, when setting voltage, if the steps is within 5, we need

There is voltage coupling between three regulators on Tegra20 boards and

thus it is mandatory and common for all of the Tegra boards.

Regulator '*-supply' properties are always a single phandle, so
'maxItems: 1' or a $ref is not necessary. All that's needed is either
'true' or an optional 'description'. Following this clean-up, the
meta-schema will enforce this pattern.
There's one case in tree with 'innolux,n156bge-l21' having 2 phandles.
This appears to be a mistake or abuse of simple-panel as it's 2 different
voltage rails connected to 'power-supply'.

During reset the VMMC regulator doesn't reach 0V and only drops to
1.8V, furthermore the pulse width is under 200us whereas the SD
specification expect 1ms.
For this 2 reasons being able to no reset at all the VMMC during warm
reset and keep the current voltage is a good workaround. The TWL6030
allows this but needs to be aware of it and this configuration should
also be shared with the bootloader.
This is the purpose of this new property: ti,retain-on-reset

be typical for NXP i.MX SoCs. However, when SNVS is used we must
not allow SW to control enabling/disabling those regulators which
are crucial for system to boot as there is a HW limitation which
causes SW controlled regulators to be kept shut down after SNVS
reset.
Allow setting the SNVS to be used as reset target state and allow
marking those regulators which are critical for boot.

Fixed regulators do not have associated bus addresses and are typically
placed directly under the root node where their names must still be
unique despite not having a unit address.
Fix the malformed example node which had a unit address but no "reg"
property by dropping the unit address.
Also, try to make the example more useful by using the recommended
generic node name "regulator", but with a suffix reflecting the
regulator name in order to make it unique.

'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.

Some systems need to set regulators to specific states when they enter
low power modes, especially around CPUs. There are many of these modes
depending on the particular runtime state.
Currently the regulator consumers are not granted permission to change
suspend state of regulator devices, the constraints are configured at
startup. In order to allow changes in a vlotage range, we need to add
new properties for voltage range and a flag to give permission to
change the suspend voltage and suspend on/off in suspend mode.

"A bigger diffstat than usual with the kbuild changes and a tree wide
fix in the binding documentation.
Summary:
- kbuild cleanups and improvements for dtbs
- Code clean-up of overlay code and fixing for some long standing
memory leak and race condition in applying overlays
- Improvements to DT memory usage making sysfs/kobjects optional and
skipping unflattening of disabled nodes. This is part of kernel
tinification efforts.
- Final piece of removing storing the full path for every DT node.
The prerequisite conversion of printk's to use device_node format
specifier happened in 4.14.
- Sync with current upstream dtc. This brings additional checks to
dtb compiling.
- Binding doc tree wide removal of leading 0s from examples
- RTC binding documentation adding missing devices and some
consolidation of duplicated bindings
- Vendor prefix documentation for nutsboard, Silicon Storage
Technology, shimafuji, Tecon Microprocessor Technologies, DH
electronics GmbH, Opal Kelly, and Next Thing"

The mvs1 and mvs2 switches are actually called 5vs1 and 5vs2 on

also match the RPM based regulator driver which calls these by
their 5vs names (see qcom_smd-regulator.c). There aren't any
users of these regulators so far, so there aren't any concerns of
DT ABI breakage here. While we're here making updates to the
switches, also mandate usage of the OCP irq for these switches

Merge tag 'devicetree-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Rewrite of the unflattening code to avoid recursion and lessen the
stack usage.
- Rewrite of the phandle args parsing code to get rid of the fixed args
size. This is needed for IOMMU code.
- Sync to latest dtc which adds more dts style checking. These
warnings are enabled with "W=1" compiles.
- Tegra documentation updates related to the above warnings.
- A bunch of spelling and other doc fixes.
- Various vendor prefix additions.

As usual, the bulk of this release is again DT file contents.
There's a huge number of changes here, and it's challenging to give a crisp
overview of just what is in here. To start with:
New boards:
- TI-based DM3730 from LogicPD (Torpedo)
- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
- Raspberry Pi 2 DT files
- Watchdog on Meson8b
- Veyron-mickey (ASUS Chromebit) DTS
- Rockchip rk3228 SoC and eval board
- Sigma Designs Tango4
Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes.

The Maxim MAX77686 PMIC is a multi-function device with regulators,
clocks and a RTC. The DT bindings for the clocks are in a separate
file but the bindings for the regulators are inside the mfd part.
To make it consistent with the clocks portion of the binding and
because is more natural to look for regulator bindings under the
bindings/regulator sub-directory, split the regulator portion of
the DT binding and add it as a separate file.

The MAX8973/MAX77621 feature an Enhanced Transient Response(ETR)
circuit that is enabled through software. The enhanced transient
response reduces the voltage droop during large load steps by
temporarily allowing all three phases to fire in unison, slewing
total inductor current faster than would normally be possible if
all three phases continued to operate 120deg out of phase. The
enhanced transient response detector features two selectable
sensitivity settings, which select the output voltage slew rate
during load transients that triggers the ETR circuit. The sensitivity
of the ETR detector is set by the CKADV[1:0] bits in the CONTROL2
register.
Add support to configure the ETR through platform data from DT.
Update the DT binding document accordingly.

Maxim MAX77621 device is high-efficiency, three-phase,
DC-DC step-down switching regulator delivers peak
output currents up to 16A. This device is extension of
MAX8973 and compatible with the register definition.
The MAX77621 has the SHUTDOWN pin which is EN pin on the
MAX8973. On MAX77621, the SHUTDOWN pin (active low) reset
device register to its POR/OTP value. The voltage output
is enabled when SHUTDONW pin is HIGH and EN bit on VOUT
register is HIGH.
For MAX8973, VOUT is enabled when EN bit or EN pin is high.
Add support of the MAX77621 device on max8973 regulator driver

It reverts commit a4b4e0461e ("of: Add standard property for poweroff capability").
As discussed on the mailing list, it makes more sense to rename back to the
old established property name, without the vendor prefix. Problem being that
the word "source" usually tends to be used for inputs and that is out of control
of the OS. The poweroff capability is an output which simply turns the
system-power off. Also, this property might be used by drivers which power-off
the system and power back on subsequent RTC alarms. This seems to suggest to
remove "poweroff" from the property name and to choose "system-power-controller"
as the more generic name. This patchs adds the required renaming changes and
defines an helper function which checks if this property is set.

Some regulators can run on different operating modes (opmodes). This
allows systems to choose the most efficient opmode for each regulator.
This patch builds on top of (291d761 regulator: Document binding for
regulator suspend state for PM state) adding a regulator-initial-mode
DT property to configure at startup the operating mode for regulators
that support changing its mode during normal operation and a property
regulator-mode to be used in the regulator-state-[mem/disk] nodes for
regulators that supports changing its operating mode when the system
enters in a suspend state.
The set of possible modes that a regulator can operate depends on the
hardware capabilities so a list of generic operating modes can't be
provided. Instead, each hardware binding should define the list of
valid operating modes for the regulators found on that device.

Certain platforms such as DRA7 have quirky memory maps such as:
PRM_ABBLDO_DSPEVE_CTRL 0x4ae07e20
PRM_ABBLDO_IVA_CTRL 0x4ae07e24
other-registers
PRM_ABBLDO_DSPEVE_SETUP 0x4ae07e30
PRM_ABBLDO_IVA_SETUP 0x4ae07e34
These need the address range allocation to be either not reserved OR
unique allocation per register instance or use something like syscon
based solution.
By going with unique allocation per register, we are able to now have
a single compatible driver for all instances on all platforms which
use the IP block.
So, introduce a new "ti,abb-v3" compatible to allow for definitions
where explicit register definitions are provided, while maintaining
backward compatibility of older predefined register offsets provided
by "ti-abb-v1" and "ti-abb-v2".
As part of this change, we rename a few variables to indicate the
appropriate meaning.

The turn-on time of the regulator depends on the regulator device's
electrical characteristics. Sometimes regulator turn-on time also
depends on the capacitive load on the given platform and it can be
more than the datasheet value.

Add support for configure the enable ramp time through regulator
constraints so that regulator core can take this value for enable
time for that regulator.

MAINTAINERS: Update git repository

regulator: s2mps11: Convert ramp rate to uV/us and set default ramp rate

This branch contains the following changes:
- Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF
- Remove #ifdef from linux/of_platform.h to increase compiler syntax
coverage
- Bug fix for address decoding on Bimini and js2x powerpc platforms.
- miscellaneous binding changes
One note on the above. The binding changes going in from all kinds of
different trees has gotten rather out of hand. I picked up some during
this cycle, but even going though my tree isn't a great fit. Ian
Campbell has prototyped splitting the bindings and .dtb files into a
separate repository. The plan is to migrate to using that sometime in
the next few kernel releases which should get rid of a lot of the churn
on binding docs and .dts files.

This patch adds primitive DT support to the max8973 regulator driver. None
of the configuration parameters, supported in the platform data are yet
available in DT, therefore no configuration is performed if booting with
no platform data. This means, that DT instantiation can only be used on
boards, where no run-time configuration of the chip is required. In such
cases the driver can be used to scale its output voltage. In the future
support for configuration parameters should be added.

Adaptive Body Biasing (ABB) modulates transistor bias voltages
dynamically in order to optimize switching speed versus leakage.
Texas Instruments' SmartReflex 2 technology provides support for this
power management technique with Forward Body Biasing (FBB) and Reverse
Body Biasing (RBB). These modulate the body voltage of transistor
cells or blocks dynamically to gain performance and reduce leakage.
TI's SmartReflex white paper[1] has further information for usage in
conjunction with other power management techniques.
The application of FBB/RBB technique is determined for each unique
device in some process nodes, whereas, they are mandated on other
process nodes.
In a nutshell, ABB technique is implemented on TI SoC as an on-chip
LDO which has ABB module controlling the bias voltage. However, the
voltage is unique per device. These vary per SoC family and the manner
in which these techniques are used may vary depending on the Operating
Performance Point (OPP) voltage targeted. For example:
OMAP3630/OMAP4430: certain OPPs mandate usage of FBB independent of
devices.
OMAP4460/OMAP4470: certain OPPs mandate usage of FBB, while others may
optionally use FBB or optimization with RBB.
OMAP5: ALL OPPs may optionally use ABB, and ABB biasing voltage is
influenced by vset fused in s/w and requiring s/w override of
default values.
Further, two generations of ABB module are used in various TI SoCs.
They have remained mostly register field compatible, however the
register offset had switched between versions.
We introduce ABB LDO support in the form of a regulator which is
controlled by voltages denoting the desired Operating Performance
Point which is targeted. However, since ABB transition is part of OPP
change sequence, the sequencing required to ensure sane operation
w.r.t OPP change is left to the controlling driver (example: cpufreq
SoC driver) using standard regulator operations.
The driver supports all ABB modes and ability to override ABB LDO vset
control efuse based ABB mode detection etc.
Current implementation is heavily influenced by the original patch
series [2][3] from Mike Turquette. However, the current implementation
supports only device tree based information.

OMAP5 support and clock management code cleanup.
- The first step of a major sync for the ab8500 driver from Lee Jones. In
particular, the debugfs and the sysct interfaces got extended and improved.

When the bindings for the TPS6586x regulator were being proposed, I
asserted that DT node naming rules for bus child nodes should also be
applied to nodes inside the TPS6586x regulator node itself. In other
words, that each node providing regulator init data should be named
after the type of object it represented ("regulator") and hence that
some other property was required to indicate which regulator the node
described ("regulator-compatible"). In turn this led to multiple nodes
having the same name, thus requiring node names to use a unit address
to make them unique, thus requiring reg properties within the nodes and
However, subsequent discussion indicates that the rules I was asserting
only applies to standardized bus nodes, and within a device's own node,
the binding can basically do anything sane that it wants.
Hence, this change deprecates the register-compatible property, and
instead uses node names to replace this functionality. This greatly
simplifies the device tree content, making them smaller and more legible.
The code is changed such that old device trees continue to work.

we have a clock API hopefully the code can be moved elsewhere. Try to
avoid getting DTs deployed relying on the 32kHz clock by removing it
from the bindings, grep seems to tell me it's not currently used anyway.

For some hardwares ramp_delay for BUCKs is a configurable parameter which can
be configured through DT or board file.This patch adds ramp_delay to regulator
constraints and allow user to configure it for regulators which supports this
feature, through DT or board file. It will provide two ways of setting the
ramp_delay for a regulator:
First, by setting it as constraints in board file(for configurable
regulators) and set_machine_constraints() will take care of setting it on
hardware by calling(the provided) .set_ramp_delay() operation(callback).
Second, by setting it as data in regulator_desc(as fixed/default
ramp_delay rate) for a regulator in driver.
regulator_set_voltage_time_sel() will give preference to
constraints->ramp_delay while reading ramp_delay rate for regulator. Similarly
users should also take care accordingly while refering ramp_delay rate(in case
of implementing their private .set_voltage_time_sel() callbacks for different
regulators).

The helper routine is meant to be used by the regulator drivers
to extract the regulator_init_data structure from the data
that is passed from device tree.
'consumer_supplies' which is part of regulator_init_data is not extracted
as the regulator consumer mappings are passed through DT differently,
implemented in subsequent patches.
Similarly the regulator<-->parent/supply mapping is handled in
subsequent patches.
Also add documentation for regulator bindings to be used to pass
regulator_init_data struct information from device tree.
Some of the regulator properties which are linux and board specific,
are left out since its not clear if they can
be in someway embedded into the kernel or passed in from DT.
They will be revisited later.
