[RFC PATCH 0/3] media: qcom: camss: support for empty endpoint nodes

[Richard Acayan <mailingradian@gmail.com>]

This series adds support for empty endpoint nodes. It is currently RFC
because it continues an ongoing discussion on how to selectively connect
some CAMSS ports to cameras and leave others disconnected.

The SDM670 patches are for a full example. If agreed on, this should
expand to SoCs that have CAMSS.

Example SoC dtsi:

	camss: isp@00000000 {
		...

		status = "disabled";

		ports {
			#address-cells = <1>;
			#size-cells = <0>;

			port@0 {
				reg = <0>;

				camss_endpoint0: endpoint {
				};
			};

			port@1 {
				reg = <1>;

				camss_endpoint1: endpoint {
				};
			};

			port@2 {
				reg = <2>;

				camss_endpoint2: endpoint {
				};
			};
		};
	};

Example device dts:

	&camss {
		status = "okay";
	};

	&camss_endpoint1 {
		clock-lanes = <7>;
		data-lanes = <0 1 2 3>;
		remote-endpoint = <&cam_front_endpoint>;
	};

	&cci_i2c1 {
		camera@1a {
			...

			port {
				cam_front_endpoint: endpoint {
					data-lanes = <1 2 3 4>;
					link-frequencies = /bits/ 64 <360000000>;
					remote-endpoint = <&camss_endpoint1>;
				};
			};
		};
	};
