Subject: [PATCH v2 09/21] [media] platform: add video-multiplexer subdevice driver
Date: Fri, 14 Oct 2016 19:34:29 +0200 [thread overview]
Message-ID: <1476466481-24030-10-git-send-email-p.zabel@pengutronix.de> (raw)
In-Reply-To: <1476466481-24030-1-git-send-email-p.zabel@pengutronix.de>
This driver can handle SoC internal and external video bus multiplexers,
controlled either by register bit fields or by a GPIO. The subdevice
passes through frame interval and mbus configuration of the active input
to the output side.

+Video Multiplexer
+=================
+
+Video multiplexers allow to select between multiple input ports. Video received
+on the active input port is passed through to the output port. Muxes described
+by this binding may be controlled by a syscon register bitfield or by a GPIO.
+
+Required properties:
+- compatible : should be "video-multiplexer"
+- reg: should be register base of the register containing the control bitfield
+- bit-mask: bitmask of the control bitfield in the control register
+- bit-shift: bit offset of the control bitfield in the control register
+- gpios: alternatively to reg, bit-mask, and bit-shift, a single GPIO phandle
+ may be given to switch between two inputs
+- #address-cells: should be <1>
+- #size-cells: should be <0>
+- port@*: at least three port nodes containing endpoints connecting to the
+ source and sink devices according to of_graph bindings. The last port is
+ the output port, all others are inputs.
+
+Example:
+
+syscon {
+ compatible = "syscon", "simple-mfd";
+
+ mux {
+ compatible = "video-multiplexer";
+ /* Single bit (1 << 19) in syscon register 0x04: */
+ reg = <0x04>;
+ bit-mask = <1>;
+ bit-shift = <19>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ mux_in0: endpoint {
+ remote-endpoint = <&video_source0_out>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ mux_in1: endpoint {
+ remote-endpoint = <&video_source1_out>;
+ };
+ };
+
+ port@2 {
+ reg = <2>;
+
+ mux_out: endpoint {
+ remote-endpoint = <&capture_interface_in>;
+ };
+ };
+ };
+};
