24 # Client device subnode's properties
29 Pinctrl node's client devices use subnodes for desired pin configuration.
30 Client device subnodes use below standard properties.
35 each entry consists of 6 integers and represents the mux and config
36 setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
37 mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
38 be found in <arch/arm/boot/dts/imxrt1170-pinfunc.h>. The last
39 integer CONFIG is the pad setting value like pull-up on this pin. Please
40 refer to i.MXRT1170 Reference Manual for detailed CONFIG settings.
