dt-bindings: iio: adc: max1363 etc i2c ADC binding conversion
Split the binding in two to reflect the threshold monitor capabilities and hence interrupts vs the more straight forward parts that don't have this facility. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Rob Herring <robh@kernel.org>

* Maxim 1x3x/136x/116xx Analog to Digital Converter (ADC)
|
||||
|
||||
The node for this driver must be a child node of a I2C controller, hence
|
||||
all mandatory properties for your controller must be specified. See directory:
|
||||
|
||||
Documentation/devicetree/bindings/i2c
|
||||
|
||||
for more details.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be one of
|

- reg: Should contain the ADC I2C address
|
||||
|
||||
Optional properties:
|
||||
- vcc-supply: phandle to the regulator that provides power to the ADC.
|
||||
- vref-supply: phandle to the regulator for ADC reference voltage.
|
||||
- interrupts: IRQ line for the ADC. If not used the driver will use
|
||||
polling.
|
||||
|
||||
Example:
|
||||
adc: max11644@36 {
|
||||
compatible = "maxim,max11644";
|
||||
reg = <0x36>;
|
||||
vref-supply = <&adc_vref>;
