- io-channels

  Usage:      optional

  Value type: List of <phandle u32>

  Definition: List of phandle and IIO specifier pairs, one pair

		for each IIO input to the device. Note: if the

		IIO provider specifies '0' for #io-channel-cells,

		then only the phandle portion of the pair will appear.

  Usage:      optional

  Value type: List of <string>

  Definition: List of IIO input name strings sorted in the same

		order as the io-channels property. Consumer drivers

		will use io-channel-names to match IIO input names

		with IIO specifiers.
