[PATCH 1/4] dt-bindings: mfd: ricoh,rn5t618: ADC related nodes and properties

From: Andreas Kemnade <andreas@kemnade.info>
Date: 2021-07-03 08:42:53
Also in: linux-devicetree, linux-iio, lkml
Subsystem: multifunction devices (mfd), open firmware and flattened device tree bindings, the rest · Maintainers: Lee Jones, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Add ADC related nodes and properties. This will allow to wire
up ADC channels to consumers, especially to measure input voltages
by the power subdevice.
