[PATCH 0/2] arm64: dts: mediatek: mt6359: give regulators unique names

[David Lechner]

While working on this regulator in U-Boot, I noticed that the regulator
names were not unique. This is considered an error in U-Boot and we get
the following error messages:

mt6359_regulator ldo_vrfck_1: 'regulator-name' has nonunique value: 'vrfck
mt6359_regulator ldo_vemc_1: 'regulator-name' has nonunique value: 'vemc

To fix, we add the _1 suffix regulator-name devicetree property to match
the same pattern seen in the node names.

[David Lechner]

Change the regulator-name properties to be unique for all regulators.
U-Boot cannot handle duplicate names.

[PATCH 2/2] dt-bindings: regulator: mt6359: make regulator names unique

[David Lechner]

Update the example devicetree with unique regulator names for all
regulators. This reflects the same change made to the actual .dtsi file.

Thanks!

[2/2] dt-bindings: regulator: mt6359: make regulator names unique
      commit: be704107e79696e855aa41e901a926039b6d2410

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
