    1 * Freescale i.MX7ULP IOMUX Controller
    2 
    3 i.MX 7ULP has three IOMUXC instances: IOMUXC0 for M4 ports, IOMUXC1 for A7
    4 ports and IOMUXC DDR for DDR interface.
    5 
    6 Note:
    7 This binding doc is only for the IOMUXC1 support in A7 Domain and it only
    8 supports generic pin config.
    9 
   10 Please refer to fsl,imx-pinctrl.txt in this directory for common binding
   11 part and usage.

   13 Required properties:
   14 - compatible:   "fsl,imx7ulp-iomuxc1".
   15 - fsl,pins:     Each entry consists of 5 integers which represents the mux
   16                 and config setting for one pin. The first 4 integers
   17                 <mux_conf_reg input_reg mux_mode input_val> are specified
   18                 using a PIN_FUNC_ID macro, which can be found in
   19                 imx7ulp-pinfunc.h in the device tree source folder.
   20                 The last integer CONFIG is the pad setting value like
   21                 pull-up on this pin.
   22 
   23                 Please refer to i.MX7ULP Reference Manual for detailed
   24                 CONFIG settings.
