  1. * Freescale IMX51 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,imx51-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 imx51 datasheet for the valid pad
  10. config settings.
  11. CONFIG bits definition:
  12. PAD_CTL_HVE (1 << 13)
  13. PAD_CTL_HYS (1 << 8)
  14. PAD_CTL_PKE (1 << 7)
  15. PAD_CTL_PUE (1 << 6)
  16. PAD_CTL_PUS_100K_DOWN (0 << 4)
  17. PAD_CTL_PUS_47K_UP (1 << 4)
  18. PAD_CTL_PUS_100K_UP (2 << 4)
  19. PAD_CTL_PUS_22K_UP (3 << 4)
  20. PAD_CTL_ODE (1 << 3)
  21. PAD_CTL_DSE_LOW (0 << 1)
  22. PAD_CTL_DSE_MED (1 << 1)
  23. PAD_CTL_DSE_HIGH (2 << 1)
  24. PAD_CTL_DSE_MAX (3 << 1)
  25. PAD_CTL_SRE_FAST (1 << 0)
  26. PAD_CTL_SRE_SLOW (0 << 0)
  27. Refer to imx51-pinfunc.h in device tree source folder for all available
  28. imx51 PIN_FUNC_ID.
