Ilitek ILI9322 TFT panel driver with SPI control bus
This is a driver for 320x240 TFT panels, accepting a variety of input
streams that get adapted and scaled to the panel. The panel output has
960 TFT source driver pins and 240 TFT gate driver pins, VCOM, VCOML and
VCOMH outputs.
Required properties:
- compatible: "dlink,dir-685-panel", "ilitek,ili9322"
(full system-specific compatible is always required to look up configuration)
- reg: address of the panel on the SPI bus
Optional properties:
- vcc-supply: core voltage supply, see regulator/regulator.txt
- iovcc-supply: voltage supply for the interface input/output signals,
see regulator/regulator.txt
- vci-supply: voltage supply for analog parts, see regulator/regulator.txt
- reset-gpios: a GPIO spec for the reset pin, see gpio/gpio.txt
The following optional properties only apply to RGB and YUV input modes and
can be omitted for BT.656 input modes:
- pixelclk-active: see display/panel/display-timing.txt
- de-active: see display/panel/display-timing.txt
- hsync-active: see display/panel/display-timing.txt
- vsync-active: see display/panel/display-timing.txt
The panel must obey the rules for a SPI slave device as specified in
spi/spi-bus.txt
The device node can contain one 'port' child node with one child
'endpoint' node, according to the bindings defined in
media/video-interfaces.txt. This node should describe panel's video bus.
Example:
panel: display@0 {
compatible = "dlink,dir-685-panel", "ilitek,ili9322";
reg = <0>;
vcc-supply = <&vdisp>;
iovcc-supply = <&vdisp>;
vci-supply = <&vdisp>;
port {
panel_in: endpoint {
remote-endpoint = <&display_out>;
};

Binding for Olimex Ltd. LCD-OLinuXino bridge panel.
This device can be used as bridge between a host controller and LCD panels.
Currently supported LCDs are:
- LCD-OLinuXino-4.3TS
- LCD-OLinuXino-5
- LCD-OLinuXino-7
- LCD-OLinuXino-10
The panel itself contains:
- AT24C16C EEPROM holding panel identification and timing requirements
- AR1021 resistive touch screen controller (optional)
- FT5x6 capacitive touch screnn controller (optional)
- GT911/GT928 capacitive touch screen controller (optional)
The above chips share same I2C bus. The EEPROM is factory preprogrammed with
device information (id, serial, etc.) and timing requirements.
Touchscreen bingings can be found in these files:
- input/touchscreen/goodix.txt
- input/touchscreen/edt-ft5x06.txt
- input/touchscreen/ar1021.txt
Required properties:
- compatible: should be "olimex,lcd-olinuxino"
- reg: address of the configuration EEPROM, should be <0x50>
- power-supply: phandle of the regulator that provides the supply voltage
Optional properties:
- enable-gpios: GPIO pin to enable or disable the panel
- backlight: phandle of the backlight device attacked to the panel
Example:
&i2c2 {

SHARP LS037V7DW01 TFT-LCD panel
===================================
Required properties:
- compatible: "sharp,ls037v7dw01"
Optional properties:
- label: a symbolic name for the panel
- enable-gpios: a GPIO spec for the optional enable pin.
This pin is the INI pin as specified in the LS037V7DW01.pdf file.
- reset-gpios: a GPIO spec for the optional reset pin.
This pin is the RESB pin as specified in the LS037V7DW01.pdf file.
- mode-gpios: a GPIO
ordered MO, LR, and UD as specified in the LS037V7DW01.pdf file.
Required nodes:
- Video port for DPI input
This panel can have zero to five GPIOs to configure to change configuration
between QVGA and VGA mode and the scan direction. As these pins can be also
configured with external pulls, all the GPIOs are considered optional with holes
in the array.
Example
-------
Example when connected to a omap2+ based device:
lcd0: display {
compatible = "sharp,ls037v7dw01";
power-supply = <&lcd_3v3>;
enable-gpios = <&gpio5 24 GPIO_ACTIVE_HIGH>; /* gpio152, lcd INI */
reset-gpios = <&gpio5 27 GPIO_ACTIVE_HIGH>; /* gpio155, lcd RESB */
mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH /* gpio154, lcd MO */
&gpio1 2 GPIO_ACTIVE_HIGH /* gpio2, lcd LR */
&gpio1 3 GPIO_ACTIVE_HIGH>; /* gpio3, lcd UD */

remote-endpoint = <&dpi_out>;

Rockchip specific extensions for rk3066 HDMI
============================================
Required properties:
- compatible:
"rockchip,rk3066-hdmi";
- reg:
Physical base address and length of the controller's registers.
- clocks, clock-names:
Phandle to HDMI controller clock, name should be "hclk".
- interrupts:
HDMI interrupt number.
- power-domains:
Phandle to the RK3066_PD_VIO power domain.
- rockchip,grf:
This soc uses GRF regs to switch the HDMI TX input between vop0 and vop1.
- ports:
Contains one port node with two endpoints, numbered 0 and 1,
connected respectively to vop0 and vop1.
Contains one port node with one endpoint
connected to a hdmi-connector node.
- pinctrl-0, pinctrl-name:
Switch the iomux for the HPD/I2C pins to HDMI function.
Example:
hdmi: hdmi@10116000 {
compatible = "rockchip,rk3066-hdmi";
reg = <0x10116000 0x2000>;
interrupts = <GIC_SPI 64 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cru HCLK_HDMI>;
clock-names = "hclk";
power-domains = <&power RK3066_PD_VIO>;
rockchip,grf = <&grf>;
pinctrl-names = "default";
pinctrl-0 = <&hdmii2c_xfer>, <&hdmi_hpd>;
