From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Simple txt to yaml conversion. Part of a general move to convert
all the IIO bindings over to yaml.

-Aspeed ADC
-
-This device is a 10-bit converter for 16 voltage channels. All inputs are
-single ended.
-
-Required properties:
-- compatible: Should be "aspeed,ast2400-adc" or "aspeed,ast2500-adc"
-- reg: memory window mapping address and length
-- clocks: Input clock used to derive the sample clock. Expected to be the
- SoC's APB clock.
-- resets: Reset controller phandle
-- #io-channel-cells: Must be set to <1> to indicate channels are selected
- by index.
-
-Example:
- adc@1e6e9000 {
- compatible = "aspeed,ast2400-adc";
- reg = <0x1e6e9000 0xb0>;
- clocks = <&syscon ASPEED_CLK_APB>;
- resets = <&syscon ASPEED_RESET_ADC>;
- #io-channel-cells = <1>;
- };
