Unlike previous Aspeed generations, the SoC1 SCU assigns every pin a 4-bit multi-function selector field in a contiguous register range starting at SCU 0x400, eight pins per register. Only bits [2:0] of each field select the function; bit 3 is reserved read-only and must not be written. The driver therefore keeps per-pin group tables and per-function mux values, mirroring the Linux aspeed,ast2700-soc1-pinctrl driver, and shares the same device tree bindings: 220 pins, 238 groups and 217 functions with identical names, so pin states written for the Linux driver work unmodified. A few controls live outside the pin-indexed range and are handled as virtual pins: PCIERC2_PERST (SCU 0x908), the USB2 port C/D mode fields (SCU 0x3B0) and SGMII0 (SCU 0x47C). The gpio_request_enable hook restores a pin to GPIO by writing mux value 0, except for the ADC-capable balls W17..AB19 where function 1 selects GPIO and 0 selects the ADC input.
