+Freescale i.MX7 CMOS Sensor Interface
+=====================================
+
+csi node
+--------
+
+This is device node for the CMOS Sensor Interface (CSI) which enables the chip
+to connect directly to external CMOS image sensors.
+
+Required properties:
+
+- compatible : "fsl,imx7-csi";
+- reg : base address and length of the register set for the device;
+- interrupts : should contain CSI interrupt;
+- clocks : list of clock specifiers, see
+ Documentation/devicetree/bindings/clock/clock-bindings.txt for details;
+- clock-names : must contain "axi", "mclk" and "dcic" entries, matching
+ entries in the clock property;
+
+The device node shall contain one 'port' child node with one child 'endpoint'
+node, according to the bindings defined in:
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+In the following example a remote endpoint is a video multiplexer.
+
+example:
+
+ csi: csi@30710000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ compatible = "fsl,imx7-csi";
+ reg = <0x30710000 0x10000>;
+ interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clks IMX7D_CLK_DUMMY>,
+ <&clks IMX7D_CSI_MCLK_ROOT_CLK>,
+ <&clks IMX7D_CLK_DUMMY>;
+ clock-names = "axi", "mclk", "dcic";
+
+ port {
+ csi_from_csi_mux: endpoint {
+ remote-endpoint = <&csi_mux_to_csi>;
+ };
+ };
+ };

+Freescale i.MX7 Mipi CSI2
+=========================
+
+mipi_csi2 node
+--------------
+
+This is the device node for the MIPI CSI-2 receiver core in i.MX7 SoC. It is
+compatible with previous version of Samsung D-phy.
+
+Required properties:
+
+- compatible : "fsl,imx7-mipi-csi2";
+- reg : base address and length of the register set for the device;
+- interrupts : should contain MIPI CSIS interrupt;
+- clocks : list of clock specifiers, see
+ Documentation/devicetree/bindings/clock/clock-bindings.txt for details;
+- clock-names : must contain "pclk", "wrap" and "phy" entries, matching
+ entries in the clock property;
+- power-domains : a phandle to the power domain, see
+ Documentation/devicetree/bindings/power/power_domain.txt for details.
+- reset-names : should include following entry "mrst";
+- resets : a list of phandle, should contain reset entry of
+ reset-names;
+- phy-supply : from the generic phy bindings, a phandle to a regulator that
+ provides power to MIPI CSIS core;
+
+Optional properties:
+
+- clock-frequency : The IP's main (system bus) clock frequency in Hz, default
+ value when this property is not specified is 166 MHz;
+- fsl,csis-hs-settle : differential receiver (HS-RX) settle time;
+
+The device node should contain two 'port' child nodes with one child 'endpoint'
+node, according to the bindings defined in:
+ Documentation/devicetree/bindings/ media/video-interfaces.txt.
+ The following are properties specific to those nodes.
+
+port node
+---------
+
+- reg : (required) can take the values 0 or 1, where 0 shall be
+ related to the sink port and port 1 shall be the source
+ one;
+
+endpoint node
+-------------
+
+- data-lanes : (required) an array specifying active physical MIPI-CSI2
+ data input lanes and their mapping to logical lanes; this
+ shall only be applied to port 0 (sink port), the array's
+ content is unused only its length is meaningful,
+ in this case the maximum length supported is 2;
+
+example:
+
+ mipi_csi: mipi-csi@30750000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ compatible = "fsl,imx7-mipi-csi2";
+ reg = <0x30750000 0x10000>;
+ interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clks IMX7D_IPG_ROOT_CLK>,
+ <&clks IMX7D_MIPI_CSI_ROOT_CLK>,
+ <&clks IMX7D_MIPI_DPHY_ROOT_CLK>;
+ clock-names = "pclk", "wrap", "phy";
+ clock-frequency = <166000000>;
+ power-domains = <&pgc_mipi_phy>;
+ phy-supply = <®_1p0d>;
+ resets = <&src IMX7_RESET_MIPI_PHY_MRST>;
+ reset-names = "mrst";
+ fsl,csis-hs-settle = <3>;
+
+ port@0 {
+ reg = <0>;
+
+ mipi_from_sensor: endpoint {
+ remote-endpoint = <&ov2680_to_mipi>;
+ data-lanes = <1>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ mipi_vc0_to_csi_mux: endpoint {
+ remote-endpoint = <&csi_mux_from_mipi_vc0>;
+ };
+ };
+ };
