-Qualcomm adreno/snapdragon MDP4 display controller
-
-Description:
-
-This is the bindings documentation for the MDP4 display controller found in
-SoCs like MSM8960, APQ8064 and MSM8660.
-
-Required properties:
-- compatible:
- * "qcom,mdp4" - mdp4
-- reg: Physical base address and length of the controller's registers.
-- interrupts: The interrupt signal from the display controller.
-- clocks: device clocks
- See ../clocks/clock-bindings.txt for details.
-- clock-names: the following clocks are required.
- * "core_clk"
- * "iface_clk"
- * "bus_clk"
- * "lut_clk"
- * "hdmi_clk"
- * "tv_clk"
-- ports: contains the list of output ports from MDP. These connect to interfaces
- that are external to the MDP hardware, such as HDMI, DSI, EDP etc (LVDS is a
- special case since it is a part of the MDP block itself).
-
- Each output port contains an endpoint that describes how it is connected to an
- external interface. These are described by the standard properties documented
- here:
- Documentation/devicetree/bindings/graph.txt
- Documentation/devicetree/bindings/media/video-interfaces.txt
-
- The output port mappings are:
- Port 0 -> LCDC/LVDS
- Port 1 -> DSI1 Cmd/Video
- Port 2 -> DSI2 Cmd/Video
- Port 3 -> DTV
-
-Optional properties:
-- clock-names: the following clocks are optional:
- * "lut_clk"
-- qcom,lcdc-align-lsb: Boolean value indicating that LSB alignment should be
- used for LCDC. This is only valid for 18bpp panels.
-
-Example:
-

-
- hdmi: hdmi at 4a00000 {
- ...
- ports {
- ...
- port at 0 {
- reg = <0>;
- hdmi_in: endpoint {

- };
- };
