It support a widely adopted, +simple, high-speed protocol primarily intended for point-to-point image and video +transmission between cameras and host devices.
Please wrap so it fits to 80 chars per line. You'll also need to document the graph nodes needed. Which ports correspond to which interfaces on the device, for instance? Please document which endpoint properties are required and whether there are any optional ones.
+
+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_reg": seninf registers base
+ "rx_reg": 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
+
+Example:
+ seninf: seninf@1a040000 {
+ compatible = "mediatek,mt8183-seninf";
+ reg = <0 0x1a040000 0 0x8000>,
+ <0 0x11C80000 0 0x6000>;
+ reg-names = "base_reg", "rx_reg";
+ 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";
+ }
