The board is equipped with different SoCs requiring different pinmuxes. For now the following peripherals are included: - LED - Power Key - Cover (gpio via hall sensor) - RC5T619 PMIC - Backlight via lm3630a - Wifi sdio chip detection (mmc-powerseq and stuff) It is based on vendor kernel but heavily reworked due to many changed bindings. Known limitations: cold colored backlight does not work due to incompatible hard coded overvoltage setting in the driver.
