From: Kieran Bingham <kieran.bingham+renesas@xxxxxxxxxxxxxxxx>
The MAX9286 exposes a GPIO controller to control the two GPIO out pins
of the chip.
These can in some configurations be used to control the power of the
cameras, and in the case of the V3M, it is used to enable power up
of the GMSL PoC regulator.
The regulator can not (currently) be moddelled as a regulator due to
probe time issues, and instead are controlled through the use of a
gpio-hog.
