+ ca* Mediatek seninf MIPI-CSI2 host driver
+
+Seninf MIPI-CSI2 host driver is a HW camera interface controller. It support
+a widely adopted, simple, high-speed protocol primarily intended for
+point-to-point image and video transmission between cameras and host devices.
+
+Required properties:
+ - compatible: "mediatek,mt8183-seninf"
+ - reg: Must contain an entry for each entry in reg-names.
+ - reg-names: Must include the following entries:
+ "base": seninf registers base
+ "rx": Rx analog registers base
+ - interrupts: interrupt number to the cpu.
+ - clocks : clock name from clock manager.
+ - clock-names: must be CLK_CAM_SENINF and CLK_TOP_MUX_SENINF,
+ It is the clocks of seninf.
+ - ports : list port node of endpoint.
+ - port : describe endpoint for each remote device port connected to this
+ port.
+ reg : port reg 0 must be main camera, port reg 1 must be sub camera,
+ since seninf driver support upto 4 cameras, so camisp is reg 4.
+
+Example:
+ seninf: seninf@1a040000 {
+ compatible = "mediatek,mt8183-seninf";
+ reg = <0 0x1a040000 0 0x8000>,
+ <0 0x11c80000 0 0x6000>;
+ reg-names = "base", "rx";
+ interrupts = <GIC_SPI 251 IRQ_TYPE_LEVEL_LOW>;
+ power-domains = <&scpsys MT8183_POWER_DOMAIN_CAM>;
+ clocks = <&camsys CLK_CAM_SENINF>,
+ <&topckgen CLK_TOP_MUX_SENINF>;
+ clock-names = "CLK_CAM_SENINF", "CLK_TOP_MUX_SENINF";
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ seninf_port0_endpoint: endpoint {
+ data-lanes = <0 1 3 4>;
+ remote-endpoint = <&ov8856_endpoint>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ seninf_port1_endpoint: endpoint {
+ data-lanes = <1>;
+ remote-endpoint = <&ov02a10_endpoint>;
+ };
+ };
+
+ port@4 {
+ reg = <4>;
+
+ seninf_camisp_endpoint: endpoint {
+ remote-endpoint = <&camisp_endpoint>;
+ };
+ };
+ };
+ };
