  1. * Freescale i.MX6 UltraLite IOMUX Controller
  2. Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
  3. and usage.
  4. Required properties:
  5. - compatible: "fsl,imx6ul-iomuxc"
  6. - fsl,pins: each entry consists of 6 integers and represents the mux and config
  7. setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
  8. input_val> are specified using a PIN_FUNC_ID macro, which can be found in
  9. imx6ul-pinfunc.h under device tree source folder. The last integer CONFIG is
  10. the pad setting value like pull-up on this pin. Please refer to i.MX6 UltraLite
  11. Reference Manual for detailed CONFIG settings.
