  1. * Freescale IMX6Q 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,imx6q-iomuxc"
  6. - fsl,pins: two integers array, represents a group of pins mux and config
  7. setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
  8. pin working on a specific function, CONFIG is the pad setting value like
  9. pull-up for this pin. Please refer to imx6q datasheet for the valid pad
  10. config settings.
  11. CONFIG bits definition:
  12. PAD_CTL_HYS (1 << 16)
  13. PAD_CTL_PUS_100K_DOWN (0 << 14)
  14. PAD_CTL_PUS_47K_UP (1 << 14)
