[PATCH 1/1] dt-bindings: mfd: convert mxs-lradc.txt to yaml format

[Frank Li <Frank.Li@nxp.com>]

Convert mxs-lradc.txt to yaml format.

Additional changes:
- Only keep one example.
- Change node name to adc.
- Add clocks and #io-channel-cells.

-* Freescale MXS LRADC device driver
-
-Required properties:
-- compatible: Should be "fsl,imx23-lradc" for i.MX23 SoC and "fsl,imx28-lradc"
-              for i.MX28 SoC
-- reg: Address and length of the register set for the device
-- interrupts: Should contain the LRADC interrupts
-
-Optional properties:
-- fsl,lradc-touchscreen-wires: Number of wires used to connect the touchscreen
-                               to LRADC. Valid value is either 4 or 5. If this
-                               property is not present, then the touchscreen is
-                               disabled. 5 wires is valid for i.MX28 SoC only.
-- fsl,ave-ctrl: number of samples per direction to calculate an average value.
-                Allowed value is 1 ... 32, default is 4
-- fsl,ave-delay: delay between consecutive samples. Allowed value is
-                 2 ... 2048. It is used if 'fsl,ave-ctrl' > 1, counts at
-                 2 kHz and its default is 2 (= 1 ms)
-- fsl,settling: delay between plate switch to next sample. Allowed value is
-                1 ... 2047. It counts at 2 kHz and its default is
-                10 (= 5 ms)
