Signed-off-by: Markus Pargmann --- Notes: 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. .../devicetree/bindings/mfd/fsl-imx25-tsadc.txt | 46 ++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/fsl-imx25-tsadc.txt diff --git a/Documentation/devicetree/bindings/mfd/fsl-imx25-tsadc.txt b/Documentation/devicetree/bindings/mfd/fsl-imx25-tsadc.txt new file mode 100644 index 000000000000..a857af0eb68c --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/fsl-imx25-tsadc.txt @@ -0,0 +1,46 @@ +Freescale mx25 ADC/TSC multifunction device + +This device combines two general purpose conversion queues one used for general +ADC and the other used for touchscreens. + +Required properties: + - compatible: Should be "fsl,imx25-tsadc". + - reg: Memory range of the device. + - interrupts: Interrupt for this device as described in + interrupts/interrupts.txt + - clocks: An 'ipg' clock defined as described in clocks/clock.txt + - interrupt-controller: This device is an interrupt controller.
