-* Analog Devices AD5755 IIO Multi-Channel DAC Linux Driver
-
-Required properties:
- - compatible: Has to contain one of the following:
- adi,ad5755
- adi,ad5755-1
- adi,ad5757
- adi,ad5735
- adi,ad5737
-
- - reg: spi chip select number for the device
- - spi-cpha or spi-cpol: is the only modes that is supported
-
-Recommended properties:
- - spi-max-frequency: Definition as per
- Documentation/devicetree/bindings/spi/spi-bus.txt
-
-Optional properties:
-See include/dt-bindings/iio/ad5755.h
- - adi,ext-dc-dc-compenstation-resistor: boolean set if the hardware have an
- external resistor and thereby bypasses
- the internal compensation resistor.
- - adi,dc-dc-phase:
- Valid values for DC DC Phase control is:
- 0: All dc-to-dc converters clock on the same edge.
- 1: Channel A and Channel B clock on the same edge,
- Channel C and Channel D clock on opposite edges.
- 2: Channel A and Channel C clock on the same edge,
- Channel B and Channel D clock on opposite edges.
- 3: Channel A, Channel B, Channel C, and Channel D
- clock 90 degrees out of phase from each other.
- - adi,dc-dc-freq-hz:
