1 One-register-per-pin type device tree based pinctrl driver
8 - reg : offset and length of the register set for the mux registers
13 - pinctrl-single,register-width : pinmux register access width in bits
16   in the pinmux register
23 - pinctrl-single,bit-per-mux : boolean to indicate that one register controls
28   drive strength in the pinmux register. They're value of drive strength
35   input bias pullup in the pinmux register.
41   input bias pulldown in the pinmux register.
57   input schmitt in the pinmux register. In some silicons, there're two input
58   schmitt value (rising-edge & falling-edge) in the pinmux register.
64   configure input schmitt enable or disable in the pinmux register.
92 This driver assumes that there is only one register for each pin (unless the
97 register offset and values using pinctrl-single,pins. Only the bits specified

105 pinctrl register, and 0x118 contains the desired value of the pinctrl register.
