Notes:
Changes in v9:
- Fixed some style things.
Changes in v6:
- Removed adc-ref property and replaced it with refp and refn for positive and
negative references. The properties are optional now as the default
behaviour is a positive internal reference voltage and ADC GND as negative
reference.

create mode 100644 Documentation/devicetree/bindings/mfd/fsl-imx25-tsadc.txtBinding looks fine, but you need to change the subject line of the patch, for is it not an ARM, but MFD patch.
