2021-07-11regulator: mt6397: Remove modeset_shift from struct mt6397_regulator_infoAxel Lin1-7/+8
The shift setting can be calculated via the corresponding mask field, so remove modeset_shift. Signed-off-by: Axel Lin <axel.lin@ingics.com> Link: https://lore.kernel.org/r/20210629130503.2183574-3-axel.lin@ingics.com Signed-off-by: Mark Brown <broonie@kernel.org>
2020-07-02regulator: mt6397: Implement of_map_modeAnand K Mistry1-0/+13
Implementing of_map_mode is necessary to be able to specify operating modes in the devicetree using 'regulator-allowed-modes', and to change regulator modes.

2016-01-27regulator: mt6397: Add OF match tableJavier Martinez Canillas1-0/+7
The Documentation/devicetree/bindings/regulator/mt6397-regulator.txt doc mentions that a compatible "mediatek,mt6397-regulator" is required for the MT6397 device node but the driver doesn't provide a OF match table so the platform bus .match fallbacks to match using the driver name instead. This also means that module auto-loading is broken for this driver since the MFD driver that register the device, has a .of_compatible set so the platform .uevent callback reports a OF modalias that's not in the module.

2016-01-27regulator: mt6397: Add platform device ID tableJavier Martinez Canillas1-1/+7
The platform bus_type .match callback attempts to match the platform device name with an entry on the .id_table if provided and fallbacks to match with the driver's name if a table is not provided. Using a platform device ID to match is more explicit, allows the driver to support more than one device and also the MODULE_DEVICE_TABLE macro can be used to export the module aliases information instead of the MODULE_ALIAS.
