| |
The MAX9286 GMSL deserializer features gpio controller capabilities, as it provides 2 GPIO lines.
As establishing a regulator that uses one of the GPIO lines and enabling/disabling it at run-time in the max9286 won't work due to a circular dependency on the gpio-controller/regulator creation, allow the usage of a gpio-hog for that purpose.
The usage of the gpio-hog is required in designs where the MAX9286 GPIO lines control the remote cameras power.
