- Convert more DT code to use of_property_read_* API.
- Improve DT overlay support when adding multiple overlays.
- Convert printk's to %pOF format specifiers. Most went via subsystem
trees, but picked up the remaining orphans.
- Correct unittests to use preferred "okay" for "status" property value.
- Add a KASLR seed property.
- Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa.
- Fix modalias buffer handling.
- Clean-up of include paths for building dtbs.
- Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10 devices.
- Add nvmem bindings for MediaTek MT7623 and MT7622 SoC.
- Add compatible string for Allwinner H5 Mali-450 GPU.
- Fix links to old OpenFirmware docs with new mirror on devicetree.org.
- Remove status property from binding doc examples.

Rockchip DWC HDMI TX Encoder
|
|
============================
|
|
|
|
The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
|
|
with a companion PHY IP.
|
|
|
|
These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
|
|
Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
|
|
following device-specific properties.
|
|
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be one of the following:
|
|
"rockchip,rk3288-dw-hdmi"
|
|
"rockchip,rk3399-dw-hdmi"
|
|
- reg: See dw_hdmi.txt.
|
|
- reg-io-width: See dw_hdmi.txt. Shall be 4.
|
|
- interrupts: HDMI interrupt number
|
|
- clocks: See dw_hdmi.txt.
|
|
- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
|
|
- ports: See dw_hdmi.txt. The DWC HDMI shall have a single port numbered 0
|
|
corresponding to the video input of the controller. The port shall have two
|
|
endpoints, numbered 0 and 1, connected respectively to the vopb and vopl.
|
|
- rockchip,grf: Shall reference the GRF to mux vopl/vopb.
|
|
|
|
Optional properties
|
|
|
|
- ddc-i2c-bus: The HDMI DDC bus can be connected to either a system I2C master
|
|
or the functionally-reduced I2C master contained in the DWC HDMI. When
|
|
connected to a system I2C master this property contains a phandle to that
|
|
I2C master controller.
|
|
- clock-names: See dw_hdmi.txt. The "cec" clock is optional.
|
|
- clock-names: May contain "cec" as defined in dw_hdmi.txt.
|
|
- clock-names: May contain "grf", power for grf io.
|
|
- clock-names: May contain "vpll", external clock for some hdmi phy.
|
|
|
|
Example:
|
|
|
|
hdmi: hdmi@ff980000 {
|
|
compatible = "rockchip,rk3288-dw-hdmi";
|
|
reg = <0xff980000 0x20000>;
|
|
reg-io-width = <4>;
|
|
ddc-i2c-bus = <&i2c5>;
|
|
rockchip,grf = <&grf>;
|
|
interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&cru PCLK_HDMI_CTRL>, <&cru SCLK_HDMI_HDCP>;
|
|
clock-names = "iahb", "isfr";
|
|
ports {
|
|
hdmi_in: port {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
hdmi_in_vopb: endpoint@0 {
|
|
reg = <0>;
|
|
remote-endpoint = <&vopb_out_hdmi>;
|
|
};
|
|
hdmi_in_vopl: endpoint@1 {
|
|
reg = <1>;
|
|
remote-endpoint = <&vopl_out_hdmi>;
|
|
};
|
|
