each entry consists of 3 integers and represents the pin ID, the mux value |
|
and pad setting for the pin. The first 2 integers - pin_id and mux_val - are |
|
specified using a PIN_FUNC_ID macro, which can be found in |
|
<include/dt-bindings/pinctrl/pads-imx8qxp.h>. The last integer is |
|
the pad setting value like pull-up on this pin. Please refer to the |
|
appropriate i.MX8 Reference Manual for detailed pad CONFIG settings. |
