From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
Whilst this binding has a lot of elements they are all fairly standard.
Hence pretty much direct txt to yaml line by line conversion.

-* AT91 SAMA5D2 Analog to Digital Converter (ADC)
-
-Required properties:
- - compatible: Should be "atmel,sama5d2-adc" or "microchip,sam9x60-adc".
- - reg: Should contain ADC registers location and length.
- - interrupts: Should contain the IRQ line for the ADC.
- - clocks: phandle to device clock.
- - clock-names: Must be "adc_clk".
- - vref-supply: Supply used as reference for conversions.
- - vddana-supply: Supply for the adc device.
- - atmel,min-sample-rate-hz: Minimum sampling rate, it depends on SoC.
- - atmel,max-sample-rate-hz: Maximum sampling rate, it depends on SoC.
- - atmel,startup-time-ms: Startup time expressed in ms, it depends on SoC.
- - atmel,trigger-edge-type: One of possible edge types for the ADTRG hardware
- trigger pin. When the specific edge type is detected, the conversion will
- start. Possible values are rising, falling, or both.
- This property uses the IRQ edge types values: IRQ_TYPE_EDGE_RISING ,
- IRQ_TYPE_EDGE_FALLING or IRQ_TYPE_EDGE_BOTH
-
-Optional properties:
- - dmas: Phandle to dma channel for the ADC.
- - dma-names: Must be "rx" when dmas property is being used.
- See ../../dma/dma.txt for details.
- - #io-channel-cells: in case consumer drivers are attached, this must be 1.
- See <Documentation/devicetree/bindings/iio/iio-bindings.txt> for details.
-
-Properties for consumer drivers:
- - Consumer drivers can be connected to this producer device, as specified
- in <Documentation/devicetree/bindings/iio/iio-bindings.txt>
- - Channels exposed are specified in:
- <dt-bindings/iio/adc/at91-sama5d2_adc.txt>
-
-Example:
-
-adc: adc@fc030000 {
- compatible = "atmel,sama5d2-adc";
- reg = <0xfc030000 0x100>;
- interrupts = <40 IRQ_TYPE_LEVEL_HIGH 7>;
- clocks = <&adc_clk>;
- clock-names = "adc_clk";
- atmel,min-sample-rate-hz = <200000>;
- atmel,max-sample-rate-hz = <20000000>;
- atmel,startup-time-ms = <4>;
- vddana-supply = <&vdd_3v3_lp_reg>;
- vref-supply = <&vdd_3v3_lp_reg>;
- atmel,trigger-edge-type = <IRQ_TYPE_EDGE_BOTH>;
- dmas = <&dma0 (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) | AT91_XDMAC_DT_PERID(25))>;
- dma-names = "rx";
- #io-channel-cells = <1>;
