28 phandle for main iomuxc controller which shares the input select
29 register for daisy chain settings.

32 # Client device subnode's properties
37 Pinctrl node's client devices use subnodes for desired pin configuration.
38 Client device subnodes use below standard properties.
43 each entry consists of 6 integers and represents the mux and config
44 setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
45 mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
46 be found in <arch/arm/boot/dts/imx7d-pinfunc.h>. The last integer
47 CONFIG is the pad setting value like pull-up on this pin. Please
48 refer to i.MX7D Reference Manual for detailed CONFIG settings.

53 "mux_reg" indicates the offset of mux register.
55 "conf_reg" indicates the offset of pad configuration register.
57 "input_reg" indicates the offset of select input register.
59 "mux_val" indicates the mux value to be applied.
61 "input_val" indicates the select input value to be applied.
63 "pad_setting" indicates the pad configuration value to be applied.
