[PATCH 0/3] Mediatek Genio 1200-EVK: MT6315/MT6360 PMIC regulator supply cleanup

[Louis-Alexis Eyraud]

This series goal is to cleanup the power supplies of MT6315 and MT6360
PMIC regulators, that are either missing or incorrect in the Mediatek
Genio 1200-EVK board devicetree.

Patch 1 completes the MT6360 dt-bindings by adding the missing power
supply descriptions for its buck regulators, that already handled by
the mt6360 regulator driver.
Patch 2 adds for the board the MT6315 regulator supply properties, that
were added in the dt-bindings by [1].
Patch 3 adds for the board the MT6360 regulator supply properties and
fixes the existing one.

The series has been tested on Genio 1200-EVK board with a kernel based
on linux-next (tag: next-20260410).

[PATCH 1/3] regulator: dt-bindings: mt6360: add buck regulator supplies

[Louis-Alexis Eyraud]

MT6360 PMIC provides 2 buck and 6 ldo regulators, that have each one a
separate supply.
Currently, the supplies for the ldo regulators are described in the
dt-bindings but the ones for the buck regulators are not.

Add the descriptions for these missing supplies.

[PATCH 2/3] arm64: dts: mediatek: mt8395-genio-common: add MT6315 PMIC supplies

[Louis-Alexis Eyraud]

Mediatek Genio 1200-EVK board has two MT6315 PMICs, powered by the
board system power rail (VSYS) and connected to the SPMI interface.

Add VSYS regulator node for system power rail and the supply inputs of
these two PMICs.

[PATCH 3/3] arm64: dts: mediatek: mt8395-genio-common: add MT6360 PMIC supplies

[Louis-Alexis Eyraud]

The Mediatek Genio 1200-EVK board has a MT6360 PMIC, powered by the
board system power rail (VSYS) and an additional system power rail
(VSYS_BUCK).
In the board devicetree, the power supply inputs for its buck and ldo
regulators are either incorrect (LDO_VIN3) or missing (LDO_VIN1/2,
BUCK_VIN1/2).

So, add VSYS_BUCK regulator node and the proper supply inputs for this
PMIC.

Thanks!

[1/3] regulator: dt-bindings: mt6360: add buck regulator supplies
      https://git.kernel.org/broonie/regulator/c/a8fccc792f42

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
