* Freescale i.MX6 SLL IOMUX Controller



Please refer to fsl,imx-pinctrl.txt in this directory for common binding part

and usage.



Required properties:

- compatible: "fsl,imx6sll-iomuxc"

- fsl,pins: each entry consists of 6 integers and represents the mux and config

  setting for one pin.  The first 5 integers <mux_reg conf_reg input_reg mux_val

  input_val> are specified using a PIN_FUNC_ID macro, which can be found in

  imx6sll-pinfunc.h under device tree source folder.  The last integer CONFIG is

  the pad setting value like pull-up on this pin.  Please refer to i.MX6SLL

  Reference Manual for detailed CONFIG settings.
