     14  The LogiCVC GPIO describes the GPIO block included in the LogiCVC display
     15  controller. These are meant to be used for controlling display-related
     16  signals.
     17
     18  The controller exposes GPIOs from the display and power control registers,
     19  which are mapped by the driver as follows:
     20  - GPIO[4:0] (display control) mapped to index 0-4
     21  - EN_BLIGHT (power control) mapped to index 5
     22  - EN_VDD (power control) mapped to index 6
     23  - EN_VEE (power control) mapped to index 7
     24  - V_EN (power control) mapped to index 8
