Merge series "regulator: mt6397: Implement of_map_mode regulator_desc function" from Anand K Mistry <amistry@google.com>:
This patchset adds support for being able to change regulator modes for
the mt6397 regulator. This is needed to allow the voltage scaling
support in the MT8173 SoC to be used on the elm (Acer Chromebook R13)
and hana (several Lenovo Chromebooks) devices.
Without a of_map_mode implementation, the regulator-allowed-modes
devicetree field is skipped, and attempting to change the regulator mode
results in an error:
[ 1.439165] vpca15: mode operation not allowed
Changes in v2:
- Introduce constants in dt-bindings
- Improve conditional readability
Anand K Mistry (4):
regulator: mt6397: Move buck modes into header file
dt-bindings: regulator: mt6397: Document valid modes
regulator: mt6397: Implement of_map_mode
arm64: dts: mediatek: Update allowed mt6397 regulator modes for elm
