-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>;
- };
- };
- };
