Device-Tree bindings for Rockchip framebuffer.
Required properties:
- compatible: value should be "rockchip,rk-fb".
- rockchip,disp-mode: DUAL :for dual lcdc and dual display;
ONE_DUAL : for one lcdc and dual display.
Example:
DT entry:
fb: fb{
compatible = "rockchip,rk-fb";
rockchip,disp-mode = <DUAL>;
};
Device-Tree bindings for RockChip screen driver
Required properties:
- compatible: value should be "rockchip,screen"
- display-timings: value should be disp_timings, which defined in
lcd-xxx.dtsi file,the file should include by your board dts
Example:
creen: rk_screen{
compatible = "rockchip,screen";
display-timings = <&disp_timings>;
};
/*

Device-Tree bindings for Rockchip SoC display controller (VOP / LCDC)
VOP (Video Output Process) / LCDC is the Display Controller for the
ROCKCHIP series of SoCs which transfers the image data from a video memory
buffer to an external LCD interface.
Required properties:
- compatible: value should be one of the following
"rockchip,rk3288-lcdc"; /* for RK3288 SoCs */
"rockchip,rk3368-lcdc"; /* for RK3368 SoCs */
"rockchip,rk322x-lcdc"; /* for RK322X SoCs */
"rockchip,rk3399-lcdc"; /* for RK3399 SoCs */
- rockchip,prop: set the lcdc as primary or extend display.
- rochchip,pwr18: set the controller IO voltage,0 is 3.3v,1 is 1.8v.
- reg: physical base address and length of the LCDC registers set.
- interrupts: interrupt number to the cpu and interrupt proterties.
- pinctrl-names: must contain a "default" entry.
- pinctrl-0: pin control group to be used for this controller.
- pinctrl-1: pin control group to be used for gpio.
- clocks: must include clock specifiers corresponding to entries in the
clock-names property.
- clock-names: list of clock names sorted in the same order as the clocks
property..
Optional Properties:
- rockchip,debug: printk debug message.
- rockchip,mirror: the lcdc mirror function.
- lcd_en:lcd_en: contain power control for lcd.
- rockchip,power_type: power type,GPIO or REGULATOR.
- gpios: pin number for gpio.
- rockchip,delay: delay time after set power.
Example:
SoC specific DT entry:
lcdc1: lcdc@ff940000 {
compatible = "rockchip,rk3288-lcdc";
rockchip,prop = <PRMRY>;
rochchip,pwr18 = <0>;
reg = <0xff940000 0x10000>;
interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
pinctrl-names = "default", "gpio";
pinctrl-0 = <&lcdc0_lcdc>;
pinctrl-1 = <&lcdc0_gpio>;
status = "disabled";
clocks = <&clk_gates15 7>, <&dclk_lcdc1>, <&clk_gates15 8>, <&pd_vop1>;
clock-names = "aclk_lcdc", "dclk_lcdc", "hclk_lcdc", "pd_lcdc";
};
Board specific DT entry:
&lcdc1 {
status = "okay";
power_ctr: power_ctr {
rockchip,debug = <0>;
rockchip,mirror = <NO_MIRROR>;
lcd_en:lcd_en {
rockchip,power_type = <GPIO>;
gpios = <&gpio7 GPIO_A3 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
};
lcd_cs:lcd_cs {
rockchip,power_type = <GPIO>;
gpios = <&gpio7 GPIO_A4 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
};
};

The Rockchip display port interface should be configured based on
the type of panel connected to it.
Required properties:
- compatible: value should be "rockchip,rk32-lvds".
- reg: physical base address and length of the LVDS registers set.
- interrupts: interrupt number to the cpu and interrupt proterties.
- clocks: must include clock specifiers corresponding to entries in the
clock-names property.
- clock-names: list of clock names sorted in the same order as the clocks
property..
