From: Ronald Claveau <[email protected]> Some values change per variant, add the structure to manage it. Add an enum khadas_mcu_type used as value to match. Also introduce khadas_mcu_fan_pdata to pass fan register address, a table named levels to get fan-supported levels on the MCU, and the number of levels to the fan sub-driver, removing the hardcoded constants.
