If enum values are defined, but never used, pinmux_pins[] contains (zero-filled) holes. Such entries are treated as pin zero, which was registered before, thus leading to pinctrl registration failures, as seen on sh7722: sh-pfc pfc-sh7722: pin 0 already registered sh-pfc pfc-sh7722: error during pin registration sh-pfc pfc-sh7722: could not register: -22 sh-pfc: probe of pfc-sh7722 failed with error -22 Remove GPIO_PH[0-7] from the enum to fix this.
