title: Xylon LogiCVC GPIO controller
maintainers:

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