Cadence DSI bridge
==================
The Cadence DSI bridge is a DPI to DSI bridge supporting up to 4 DSI lanes.
Required properties:
- compatible: should be set to "cdns,dsi".
- reg: physical base address and length of the controller's registers.
- interrupts: interrupt line connected to the DSI bridge.
- clocks: DSI bridge clocks.
- clock-names: must contain "dsi_p_clk" and "dsi_sys_clk".
- phys: phandle link to the MIPI D-PHY controller.
- phy-names: must contain "dphy".
- #address-cells: must be set to 1.
- #size-cells: must be set to 0.
Optional properties:
- resets: DSI reset lines.
- reset-names: can contain "dsi_p_rst".
Required subnodes:
- ports: Ports as described in Documentation/devicetree/bindings/graph.txt.
2 ports are available:
* port 0: this port is only needed if some of your DSI devices are
controlled through an external bus like I2C or SPI. Can have at
most 4 endpoints. The endpoint number is directly encoding the
DSI virtual channel used by this device.
* port 1: represents the DPI input.
Other ports will be added later to support the new kind of inputs.
- one subnode per DSI device connected on the DSI bus. Each DSI device should
contain a reg property encoding its virtual channel.
Cadence DPHY
============
Cadence DPHY block.
Required properties:
- compatible: should be set to "cdns,dphy".
- reg: physical base address and length of the DPHY registers.
- clocks: DPHY reference clocks.
- clock-names: must contain "psm" and "pll_ref".
- #phy-cells: must be set to 0.
Example:
dphy0: dphy@fd0e0000{
compatible = "cdns,dphy";
reg = <0x0 0xfd0e0000 0x0 0x1000>;
clocks = <&psm_clk>, <&pll_ref_clk>;
clock-names = "psm", "pll_ref";
#phy-cells = <0>;
};
dsi0: dsi@fd0c0000 {
compatible = "cdns,dsi";
reg = <0x0 0xfd0c0000 0x0 0x1000>;
clocks = <&pclk>, <&sysclk>;
clock-names = "dsi_p_clk", "dsi_sys_clk";
interrupts = <1>;
phys = <&dphy0>;
phy-names = "dphy";
#address-cells = <1>;
#size-cells = <0>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@1 {
reg = <1>;
dsi0_dpi_input: endpoint {
remote-endpoint = <&xxx_dpi_output>;
};
};
};
panel: dsi-dev@0 {
compatible = "<vendor,panel>";
reg = <0>;
};
};
or
dsi0: dsi@fd0c0000 {
compatible = "cdns,dsi";
reg = <0x0 0xfd0c0000 0x0 0x1000>;
clocks = <&pclk>, <&sysclk>;
clock-names = "dsi_p_clk", "dsi_sys_clk";
interrupts = <1>;
phys = <&dphy1>;
phy-names = "dphy";
#address-cells = <1>;
#size-cells = <0>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
dsi0_output: endpoint@0 {
reg = <0>;
remote-endpoint = <&dsi_panel_input>;
};
};
port@1 {
reg = <1>;
dsi0_dpi_input: endpoint {
remote-endpoint = <&xxx_dpi_output>;
};
};
};
};
i2c@xxx {
panel: panel@59 {
compatible = "<vendor,panel>";
reg = <0x59>;
port {
dsi_panel_input: endpoint {
remote-endpoint = <&dsi0_output>;
};
};
};
};
