[PATCH 0/9] MT6365 PMIC support cleanup

[PATCH 0/9] MT6365 PMIC support cleanup

[Louis-Alexis Eyraud]

Several Mediatek and Radxa boards, based on MT8370, MT8390 or MT8395
SoC, integrate the MT6365 PMIC, that is a MT6359P variant:
 - Mediatek Genio 1200-EVK
 - Mediatek Genio 700-EVK
 - Mediatek Genio 510-EVK
 - Radxa NIO-12L
It is compatible with the MT6359 PMIC.

But both MT6365 PMIC support and compatibility were never expressed in
the dt-bindings and there is no MT6365 include file as well.
So, since these board support was introduced, their devicetrees use the
mt6359 include file to enable this PMIC support. 

The goal of this series is to clean this support by adding the missing
compatible strings for this MFD main and subdevices in the dt-bindings,
and add a include for MT6365 definitions to replace the MT6359 include
in these board devicetrees and for future ones (like Genio 520/720
EVKs).

The series is based on linux-next tree (tag: next-20260428) and has
been tested on Mediatek Genio 510, 700 and 1200-EVK boards.

[PATCH 1/9] dt-bindings: mfd: mediatek: mt6397: Add rtc for MT6359

[Louis-Alexis Eyraud]

The rtc block of MT6359 PMIC is compatible with the one found in MT6358
but this compatibility was never expressed in the dt-bindings, so add
the missing compatible string for the rtc subnode.

[PATCH 5/9] arm64: dts: mediatek: mt6359: use proper compatible for rtc

[Louis-Alexis Eyraud]

The MT6359 PMIC include file uses directly "mediatek,mt6358-rtc"
compatible string for the rtc subnode, but not its own compatible
string.
Now that the "mediatek,mt6359-rtc" compatible is properly declared in
the dt-bindings, use it with "mediatek,mt6358-rtc" as fallback.

[PATCH 6/9] arm64: dts: mediatek: add MT6365 PMIC include

[Louis-Alexis Eyraud]

The MT6365 PMIC, compatible with MT6359 PMIC, never had its own include
file so the boards that integrates this PMIC used mt6359.dtsi in their
devicetree to enable its support.

So, add the mt6365 include file for the MT6365 definitions and labels.
In order not to duplicate all of them, make it include mt6359.dtsi and
override the compatible strings for the MFD main and sub devices with
the MT6365 ones.
