description:
each entry consists of 6 integers and represents the mux and config
setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
be found in <include/dt-bindings/pinctrl/pins-imxrt1050.h>. The last
integer CONFIG is the pad setting value like pull-up on this pin. Please
refer to i.MXRT1050 Reference Manual for detailed CONFIG settings.
