Subsystem:
max9286 quad gmsl deserializer driver, media input infrastructure (v4l/dvb), open firmware and flattened device tree bindings, the rest · Maintainers:
Jacopo Mondi, Kieran Bingham, Laurent Pinchart, Niklas Söderlund, Mauro Carvalho Chehab, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Power supplies for the ports can be controlled per port depending on the hardware design. Support per-port supplies in the DT bindings, mutually exclusive with the global supply.
