Pull devicetree updates from Rob Herring:
- Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
much needed help.
- 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

- 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

automation.

Pull spi updates from Mark Brown:
"The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus
types, causing updates to most SPI device drivers. The branch with
that on has been cross merged with a couple of other trees which added
new SPI drivers this cycle, I'm not expecting any build issues
resulting from the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than
numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and

Convert the TPS62360 regulator binding to DT schema format
using json-schema.
This also removes redundant "ti,enable-force-pwm" property
from the example. The property description was removed from the
original text binding file by commit 9a00630c3d ("regulator:
tps62360: support force PWM mode via regulator mode"), but a
reference to it remained in the example.

The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. Many schemas for
phandle-array properties aren't clear in the schema which case applies
though the description usually describes it.
The array of phandles case boils down to needing:
items:
maxItems: 1
The phandle plus args cases should typically take this form:
items:
- items:
- description: A phandle
- description: 1st arg cell
- description: 2nd arg cell
With this change, some examples need updating so that the bracketing of
property values matches the schema.

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77686 datasheet describes the interrupt line as active low
with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

regulator/clock: Convert the s2m and s5m DT bindings to schema
Tagged to allow further bindings to rely on these.
Signed-off-by: Lee Jones <lee.jones@linaro.org>
Hi All,
Changes since v2
================
1. Add Stephen's and Rob's tags.
2. Correct inb-supply description in patch 10/10.
Changes since v2
================
1. Add Rob's tags.
2. Remove "regulator-name" from properties (all regulator dtschema).
3. Move "unevaluatedProperties" higher to make code easier to read (all regulator dtschema).
4. Add ref-type to op-mode property (patch 6: s5m8767 regulators).
Changes since v1
================
1. Drop DTS patches - applied.
2. Fully remove bindings/regulator/samsung,s5m8767.txt .
3. Minor subject reformatting and few typos in text.
Intro
=====
This patchset converts all devicetree bindings of Samsung S2M and S5M
PMIC devices from txt to dtschema.
It includes also two fixes because later conversion depends on it
(contextually).
Merging/dependencies
====================
1. Regulator related binding changes depend on first two commits (the
fixes), because of context.
2. The mfd bindings depend on clock and regulator bindings.
The fixes and bindings changes (patches 1-10) should go via the same
tree. For example regulator or mfd tree.
Another alternative is that regulator patches (1-2, 4-6) go via Mark who
later gives MFD a stable branch/tag to pull. Then the clock and MFD
bindings would go on top via MFD tree. Or any other setup you would like
to have.
Overview of devices
===================
Essentially all Samsung S2M and S5M PMICs are very similar devices. They
provide the same functionality: regulators, RTC, 2 or 3 clocks and main
power management (e.g. power cut to SoC).
The differences are mostly in registers layout and number of regulators.
The drivers are built around one common part, mfd/sec-core.c, and share
some drivers between devices:
1. MFD sec-core for all devices,
1. one clock driver for most of devices,
2. one RTC driver for all devices,
3. three regulator drivers.
The regulator drivers were implementing slightly different features,
therefore one regulator binding for all devices does not make much
sense. However the clock device binding can be shared.
The final dtschema bindings try to implement this - share only the clock
bindings.
Best regards,
Krzysztof

The driver and its bindings, before commit 04f9f068a6 ("regulator:
s5m8767: Modify parsing method of the voltage table of buck2/3/4") were
requiring to provide at least one safe/default voltage for DVS registers
if DVS GPIO is not being enabled.
IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the
s5m8767,pmic-buck2-dvs-voltage should still be present and contain one
voltage.
This requirement was coming from driver behavior matching this condition
(none of DVS GPIO is enabled): it was always initializing the DVS
selector pins to 0 and keeping the DVS enable setting at reset value
(enabled). Therefore if none of DVS GPIO is enabled in devicetree,
driver was configuring the first DVS voltage for buck[234].
Mentioned commit 04f9f068a6 ("regulator: s5m8767: Modify parsing
method of the voltage table of buck2/3/4") broke it because DVS voltage
won't be parsed from devicetree if DVS GPIO is not enabled. After the
change, driver will configure bucks to use the register reset value as
voltage which might have unpleasant effects.
Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled
in devicetree (therefore DVS voltage is also not parsed), explicitly
disable it.
