dt-bindings: mfd: armltd: Move Arm board syscon's to separate schema

2023-11-01T10:02:18+00:00

The Arm Ltd board bindings are a bit unusual in that they define child
nodes for various syscon's. The schemas are also incomplete as they lack
constraints on having additional properties and some properties are
missing. As the bindings for the different platforms only vary by
compatibles, combine them into a single schema doc.

Add the "arm,im-pd1-syscon" compatible which was not documented. Add
"ranges", "#address-cells", and "#size-cells properties which were
missing.

With this, fix the error exposed in the register-bit-led binding.

Convert the binding to DT schema format.

The sub-functions of this MFD device do not have their own compatible
string and are thus described directly in the MFD binding document
after being converted to YAML.

dt-bindings: mfd: qcom,spmi-pmic: Drop unused labels from examples

2023-11-01T10:02:15+00:00

There's not much point in having unused labels in the binding example,
so drop them.

This patch was originally motivated by ea25d61b448a ("arm64: dts: qcom:
Use plural _gpios node label for PMIC gpios") updating all dts files to
use the plural _gpios label instead of the singular _gpio as label but
this example wasn't updated. But since we should just drop the label
alltogether, do that.

dt-bindings: mfd: mt6397: Split out compatible for MediaTek MT6366 PMIC

2023-11-01T10:02:14+00:00

The MT6366 PMIC is mostly, but not fully, compatible with MT6358. It has
a different set of regulators. Specifically, it lacks the camera related
VCAM* LDOs and VLDO28, but has additional VM18, VMDDR, and VSRAM_CORE LDOs.

The PMICs contain a chip ID register that can be used to detect which
exact model is preset, so it is possible to share a common base
compatible string.

Add a separate compatible for the MT6366 PMIC, with a fallback to the
MT6358 PMIC.

dt-bindings: mfd: Add missing unevaluatedProperties on child node schemas

2023-11-01T10:02:13+00:00

Just as unevaluatedProperties or additionalProperties are required at
the top level of schemas, they should (and will) also be required for
child node schemas. That ensures only documented properties are
present for any node.

Add unevaluatedProperties as needed, and then add any missing properties
flagged by the addition.

dt-bindings: mfd: x-powers,axp152: Make interrupt optional for more chips

2023-11-01T10:02:13+00:00

All X-Powers PMICs described by this binding have an IRQ pin, and so
far (almost) all boards connected this to some NMI pin or GPIO on the SoC
they are connected to.
However we start to see boards that omit this connection, and technically
the IRQ pin is not essential to the basic PMIC operation.

The existing Linux driver allows skipping the IRQ pin setup for two chips
already, so update the binding to also make the DT property optional for
the missing chip. And while we are at it, add the AXP313a to that list,
as they are actually boards out there not connecting the IRQ pin.

This allows to have DTs correctly describing those boards not wiring up
the interrupt.
