1 Rockchip DWC HDMI TX Encoder
2 ============================
4 The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
5 with a companion PHY IP.
7 These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
8 Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
9 following device-specific properties.
14 - compatible: should be one of the following:
15 "rockchip,rk3288-dw-hdmi"
16 "rockchip,rk3328-dw-hdmi"
17 "rockchip,rk3399-dw-hdmi"
18 - reg: See dw_hdmi.txt.
19 - reg-io-width: See dw_hdmi.txt. Shall be 4.
20 - interrupts: HDMI interrupt number
21 - clocks: See dw_hdmi.txt.
22 - clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
23 - ports: See dw_hdmi.txt. The DWC HDMI shall have a single port numbered 0
24 corresponding to the video input of the controller. The port shall have two
25 endpoints, numbered 0 and 1, connected respectively to the vopb and vopl.
26 - rockchip,grf: Shall reference the GRF to mux vopl/vopb.
30 - ddc-i2c-bus: The HDMI DDC bus can be connected to either a system I2C master
31 or the functionally-reduced I2C master contained in the DWC HDMI. When
32 connected to a system I2C master this property contains a phandle to that
33 I2C master controller.
34 - clock-names: See dw_hdmi.txt. The "cec" clock is optional.
35 - clock-names: May contain "cec" as defined in dw_hdmi.txt.
36 - clock-names: May contain "grf", power for grf io.
37 - clock-names: May contain "vpll", external clock for some hdmi phy.
38 - phys: from general PHY binding: the phandle for the PHY device.
39 - phy-names: Should be "hdmi" if phys references an external phy.
