-Cadence MIPI-CSI2 RX controller
-===============================
-
-The Cadence MIPI-CSI2 RX controller is a CSI-2 bridge supporting up to 4 CSI
-lanes in input, and 4 different pixel streams in output.
-
-Required properties:
- - compatible: must be set to "cdns,csi2rx" and an SoC-specific compatible
- - reg: base address and size of the memory mapped region
- - clocks: phandles to the clocks driving the controller
- - clock-names: must contain:
- * sys_clk: main clock
- * p_clk: register bank clock
- * pixel_if[0-3]_clk: pixel stream output clock, one for each stream
- implemented in hardware, between 0 and 3
-
-Optional properties:
- - phys: phandle to the external D-PHY, phy-names must be provided
- - phy-names: must contain "dphy", if the implementation uses an
- external D-PHY
-
-Required subnodes:
- - ports: A ports node with one port child node per device input and output
- port, in accordance with the video interface bindings defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt. The
- port nodes are numbered as follows:
-
- Port Description
- -----------------------------
- 0 CSI-2 input
- 1 Stream 0 output
- 2 Stream 1 output
- 3 Stream 2 output
- 4 Stream 3 output
-
- The stream output port nodes are optional if they are not
- connected to anything at the hardware level or implemented
- in the design.Since there is only one endpoint per port,
- the endpoints are not numbered.
-
-
-Example:
-
-csi2rx: csi-bridge@0d060000 {
- compatible = "cdns,csi2rx";
- reg = <0x0d060000 0x1000>;
- clocks = <&byteclock>, <&byteclock>
- <&coreclock>, <&coreclock>,
- <&coreclock>, <&coreclock>;
- clock-names = "sys_clk", "p_clk",
- "pixel_if0_clk", "pixel_if1_clk",
- "pixel_if2_clk", "pixel_if3_clk";
-
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@0 {
- reg = <0>;
-
- csi2rx_in_sensor: endpoint {
- remote-endpoint = <&sensor_out_csi2rx>;
- clock-lanes = <0>;
- data-lanes = <1 2>;
- };
- };
-
- port@1 {
- reg = <1>;
-
- csi2rx_out_grabber0: endpoint {
- remote-endpoint = <&grabber0_in_csi2rx>;
- };
- };
-
- port@2 {
- reg = <2>;
-
- csi2rx_out_grabber1: endpoint {
- remote-endpoint = <&grabber1_in_csi2rx>;
- };
- };
-
- port@3 {
- reg = <3>;
-
- csi2rx_out_grabber2: endpoint {
- remote-endpoint = <&grabber2_in_csi2rx>;
- };
- };
-
- port@4 {
- reg = <4>;
-
- csi2rx_out_grabber3: endpoint {
- remote-endpoint = <&grabber3_in_csi2rx>;
- };
- };
- };
-};
