Merge series "regulator: da9211: support changing modes" from Anand K Mistry <amistry@google.com>:
This patchset adds support for being able to change regulator modes for
the da9211 regulator. This is needed to allow the voltage scaling
support in the MT8173 SoC to be used in the elm (Acer Chromebook R13)
and hana (several Lenovo Chromebooks) devices.
Anand K Mistry (4):
regulator: da9211: Move buck modes into header file
dt-bindings: regulator: da9211: Document allowed modes
regulator: da9211: Implement of_map_mode
arm64: dts: mediatek: Update allowed regulator modes for elm boards
