+Subject: [PATCH 03/22] dt-bindings: improve BCM6345 GPIO binding documentation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Convert existing BCM6345 GPIO binding documentation to YAML and add binding
+documentation for the GPIO controller found in BCM6318, BCM6328, BCM6358,
+BCM6362, BCM6368 and BCM63268 SoCs.

+-Bindings for the Broadcom's brcm,bcm6345-gpio memory-mapped GPIO controllers.
+-
+-These bindings can be used on any BCM63xx SoC. However, BCM6338 and BCM6345
+-are the only ones which don't need a pinctrl driver.
+-BCM6338 have 8-bit data and dirout registers, where GPIO state can be read
+-and/or written, and the direction changed from input to output.
+-BCM6345 have 16-bit data and dirout registers, where GPIO state can be read
+-and/or written, and the direction changed from input to output.
+-
+-Required properties:
+-	- compatible: should be "brcm,bcm6345-gpio"
+-	- reg-names: must contain
+-		"dat" - data register
+-		"dirout" - direction (output) register
+-	- reg: address + size pairs describing the GPIO register sets;
+-		order must correspond with the order of entries in reg-names
+-	- #gpio-cells: must be set to 2. The first cell is the pin number and
+-			the second cell is used to specify the gpio polarity:
+-			0 = active high
+-			1 = active low
+-	- gpio-controller: Marks the device node as a gpio controller.
+-
+-Optional properties:
+-	- native-endian: use native endian memory.
+-
+-Examples:
+-	- BCM6338:
+-	gpio: gpio-controller@fffe0407 {
+-		compatible = "brcm,bcm6345-gpio";
+-		reg-names = "dirout", "dat";
+-		reg = <0xfffe0407 1>, <0xfffe040f 1>;
+-
+-		#gpio-cells = <2>;
+-		gpio-controller;
+-	};
+-
+-	- BCM6345:
+-	gpio: gpio-controller@fffe0406 {
+-		compatible = "brcm,bcm6345-gpio";
+-		reg-names = "dirout", "dat";
+-		reg = <0xfffe0406 2>, <0xfffe040a 2>;
+-		native-endian;
+-
+-		#gpio-cells = <2>;
+-		gpio-controller;
+-	};
