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 <arch/arm/boot/dts/imxrt1050-pinfunc.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.
