-Pinctrl-based I2C Bus DeMux
-
-This binding describes an I2C bus demultiplexer that uses pin multiplexing to
-route the I2C signals, and represents the pin multiplexing configuration using
-the pinctrl device tree bindings. This may be used to select one I2C IP core at
-runtime which may have a better feature set for a given task than another I2C
-IP core on the SoC. The most simple example is to fall back to GPIO bitbanging
-if your current runtime configuration hits an errata of the internal IP core.

-Required properties:
-- compatible: "i2c-demux-pinctrl"
-- i2c-parent: List of phandles of I2C masters available for selection. The first
-	      one will be used as default.
-- i2c-bus-name: The name of this bus. Also needed as pinctrl-name for the I2C
-		parents.
-
-Furthermore, I2C mux properties and child nodes. See i2c-mux.yaml in this
-directory.
-
-Example:
-
-Here is a snipplet for a bus to be demuxed. It contains various i2c clients for
-HDMI, so the bus is named "i2c-hdmi":
-
-	i2chdmi: i2c@8 {
-
-		compatible = "i2c-demux-pinctrl";
-		i2c-parent = <&gpioi2c>, <&iic2>, <&i2c2>;
-		i2c-bus-name = "i2c-hdmi";
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		ak4643: sound-codec@12 {
-			compatible = "asahi-kasei,ak4643";
-
-			#sound-dai-cells = <0>;
-			reg = <0x12>;
-		};
-
-		composite-in@20 {
-			compatible = "adi,adv7180";
-			reg = <0x20>;
-			remote = <&vin1>;
-
-			port {
-				adv7180: endpoint {
-					bus-width = <8>;
-					remote-endpoint = <&vin1ep0>;
-				};
-			};
-		};
-
-		hdmi@39 {
-			compatible = "adi,adv7511w";
-			reg = <0x39>;
-			interrupt-parent = <&gpio1>;
-			interrupts = <15 IRQ_TYPE_LEVEL_LOW>;
-
-			adi,input-depth = <8>;
-			adi,input-colorspace = "rgb";
-			adi,input-clock = "1x";
-			adi,input-style = <1>;
-			adi,input-justification = "evenly";
-
-			ports {
-				#address-cells = <1>;
-				#size-cells = <0>;
-
-				port@0 {
-					reg = <0>;
-					adv7511_in: endpoint {
-						remote-endpoint = <&du_out_lvds0>;
-					};
-				};
-
-				port@1 {
-					reg = <1>;
-					adv7511_out: endpoint {
-						remote-endpoint = <&hdmi_con>;
-					};
-				};
-			};
-		};
-	};
-
-And for clarification, here are the snipplets for the i2c-parents:
-
-	gpioi2c: i2c@9 {
-		#address-cells = <1>;
-		#size-cells = <0>;
-		compatible = "i2c-gpio";
-		gpios = <&gpio5 6 GPIO_ACTIVE_HIGH /* sda */
-			 &gpio5 5 GPIO_ACTIVE_HIGH /* scl */
-			>;
-		i2c-gpio,delay-us = <5>;
-	};
-
-...
-
-&i2c2	{
-	pinctrl-0 = <&i2c2_pins>;
-	pinctrl-names = "i2c-hdmi";
-
-	clock-frequency = <100000>;
-};
-
-...
-
-&iic2	{
-	pinctrl-0 = <&iic2_pins>;
-	pinctrl-names = "i2c-hdmi";
-
-	clock-frequency = <100000>;
-};
-
-Please note:
-
-- pinctrl properties for the parent I2C controllers need a pinctrl state
-  with the same name as i2c-bus-name, not "default"!
-
-- the i2c masters must have their status "disabled". This driver will
-  enable them at runtime when needed.
