-Device-Tree bindings for sigma delta modulator
-
-Required properties:
-- compatible: should be "ads1201", "sd-modulator". "sd-modulator" can be use
-	as a generic SD modulator if modulator not specified in compatible list.
-- #io-channel-cells = <0>: See the IIO bindings section "IIO consumers".

-Example node:
-
-	ads1202: adc {
