   3 Please refer to fsl,imx-pinctrl.txt and pinctrl-bindings.txt in this directory
   4 for common binding part and usage.
   5
   6 Required properties:
   7 - compatible: "fsl,imx8mm-iomuxc"
   8 - reg: should contain the base physical address and size of the iomuxc
   9   registers.
  10
  11 Required properties in sub-nodes:
  12 - fsl,pins: each entry consists of 6 integers and represents the mux and config
  13   setting for one pin.  The first 5 integers <mux_reg conf_reg input_reg mux_val
  14   input_val> are specified using a PIN_FUNC_ID macro, which can be found in
  15   <dt-bindings/pinctrl/imx8mm-pinfunc.h>. The last integer CONFIG is
  16   the pad setting value like pull-up on this pin.  Please refer to i.MX8M Mini
  17   Reference Manual for detailed CONFIG settings.
