The SGM3804 is powered by the enable GPIO pins inputs and only supports I2C write messages. In order to add flexibility and simplify the driver, the regmap cache is enabled and populated with default values since we can't write registers when the 2 GPIOs are down. This regulator is used to provide vsn and vsn power to the Ayaneo Pocket S2 dual-DSI LCD panel.
