[PATCH 0/2] regulator: add support for SGM3804 Dual Output driver

[Neil Armstrong]

Add support for the SG Micro SGM3804 Single Inductor Dual Output
Buck/Boost Converter used to power LCD panels a provide positive
and negative power rails with configurable voltage and active
discharge function for each output.

The SGM3804 is powered by the enable GPIO pins inputs and only
supports I2C write messages. Thus we can't use the regmap
helpers directly and we need to cache the selector and
rail discharge state then setup the rails once the gpio
is enabled.
In order add flexibility, the regmap cache is enabled.

This regulator is used to provide vsn and vsn power to the
Ayaneo Pocket S2 dual-DSI LCD panel.
