* Clock bindings for Freescale i.MX6 UltraLite
Required properties:
- compatible: Should be "fsl,imx6ul-ccm"
- reg: Address and length of the register set
- #clock-cells: Should be <1>
- clocks: list of clock specifiers, must contain an entry for each required
entry in clock-names
- clock-names: should include entries "ckil", "osc", "ipp_di0" and "ipp_di1"
The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx6ul-clock.h
for the full list of i.MX6 UltraLite clock IDs.
* Freescale i.MX6 UltraLite IOMUX Controller
Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
and usage.
Required properties:
- compatible: "fsl,imx6ul-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
imx6ul-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.MX6 UltraLite
Reference Manual for detailed CONFIG settings.
