+title: Xylon LogiCVC GPIO controller
+

+
+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
