++Broadcom BCM283x Camera Interface (Unicam)
++------------------------------------------
++
++The Unicam block on BCM283x SoCs is the receiver for either
++CSI-2 or CCP2 data from image sensors or similar devices.
++
++The main platform using this SoC is the Raspberry Pi family of boards.
++On the Pi the VideoCore firmware can also control this hardware block,
++and driving it from two different processors will cause issues.
++To avoid this, the firmware checks the device tree configuration
++during boot. If it finds device tree nodes called csi0 or csi1 then
++it will stop the firmware accessing the block, and it can then
++safely be used via the device tree binding.
++
++Required properties:
++===================
++- compatible : must be "brcm,bcm2835-unicam".
++- reg : physical base address and length of the register sets for the
++ device.
++- interrupts : should contain the IRQ line for this Unicam instance.
++- clocks : list of clock specifiers, corresponding to entries in
++ clock-names property.
++- clock-names : must contain an "lp" entry, matching entries in the
++ clocks property.
++
++Unicam supports a single port node. It should contain one 'port' child node
++with child 'endpoint' node. Please refer to the bindings defined in
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Within the endpoint node the "remote-endpoint" and "data-lanes" properties
++are mandatory.
++Data lane reordering is not supported so the data lanes must be in order,
++starting at 1. The number of data lanes should represent the number of
++usable lanes for the hardware block. That may be limited by either the SoC or
++how the platform presents the interface, and the lower value must be used.
++
++Lane reordering is not supported on the clock lane either, so the optional
++property "clock-lane" will implicitly be <0>.
++Similarly lane inversion is not supported, therefore "lane-polarities" will
++implicitly be <0 0 0 0 0>.
++Neither of these values will be checked.
++
++Example:
++ csi1: csi1@7e801000 {
++ compatible = "brcm,bcm2835-unicam";
++ reg = <0x7e801000 0x800>,
++ <0x7e802004 0x4>;
++ interrupts = <2 7>;
++ clocks = <&clocks BCM2835_CLOCK_CAM1>;
++ clock-names = "lp";
++
++ port {
++ csi1_ep: endpoint {
++ remote-endpoint = <&tc358743_0>;
++ data-lanes = <1 2>;
++ };
++ };
++ };
++
++ i2c0: i2c@7e205000 {
++ tc358743: csi-hdmi-bridge@0f {
++ compatible = "toshiba,tc358743";
++ reg = <0x0f>;
++
++ clocks = <&tc358743_clk>;
++ clock-names = "refclk";
++
++ tc358743_clk: bridge-clk {
++ compatible = "fixed-clock";
++ #clock-cells = <0>;
++ clock-frequency = <27000000>;
++ };
++
++ port {
++ tc358743_0: endpoint {
++ remote-endpoint = <&csi1_ep>;
++ clock-lanes = <0>;
++ data-lanes = <1 2>;
++ clock-noncontinuous;
++ link-frequencies =
++ /bits/ 64 <297000000>;
++ };
++ };
++ };
++ };
