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 properties: $nodename: pattern: "^gpio@[0-9a-f]+$" compatible: enum: - xylon,logicvc-3.02.a-gpio reg: maxItems: 1 "#gpio-cells": const: 2 gpio-controller: true gpio-line-names: minItems: 1 maxItems: 9 required: - compatible - reg - "#gpio-cells" - gpio-controller additionalProperties: false examples: - | logicvc: logicvc@43c00000 { compatible = "xylon,logicvc-3.02.a", "syscon", "simple-mfd"; reg = <0x43c00000 0x6000>; #address-cells = <1>; #size-cells = <1>; logicvc_gpio: gpio@40 { compatible = "xylon,logicvc-3.02.a-gpio"; reg = <0x40 0x40>; gpio-controller; #gpio-cells = <2>; gpio-line-names = "GPIO0", "GPIO1", "GPIO2", "GPIO3", "GPIO4", "EN_BLIGHT", "EN_VDD", "EN_VEE", "V_EN"; }; };
