Subsystem:
open firmware and flattened device tree bindings, real time clock (rtc) subsystem, the rest · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Alexandre Belloni, Linus Torvalds
From: Denis Osterland <redacted> The devicetree documentation for the ISL1219 device tree binding is added with an short example. It is not a trivial device, because it supports two interrupt sources.
