+Broadcom Capri Pin Controller
+
+This is a pin controller for the Broadcom BCM281xx SoC family, which includes
+BCM11130, BCM11140, BCM11351, BCM28145, and BCM28155 SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible:	Must be "brcm,capri-pinctrl".
+- reg:		Base address of the PAD Controller register block and the size
+		of the block.
+
+For example, the following is the bare minimum node:
+
+	pinctrl@35004800 {
+		compatible = "brcm,capri-pinctrl";
+		reg = <0x35004800 0x430>;
+	};
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux and/or pin configuration for an
+arbitrary number of pins.  The name of the pin group node is optional and not
+used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Each pin controlled by this pin controller belong to one of three types:
+Standard, I2C, and HDMI.  Each type accepts a different set of pin config
+properties.  A list of pins and their types is provided below.
+
+Required Properties (applicable to all pins):
+
+- pins:		Multiple strings.  Specifies the name(s) of one or more pins to
+		be configured by this node.
+
+Optional Properties (for standard pins):
+
+- function:			String. Specifies the pin mux selection. Values
+				must be one of: "alt1", "alt2", "alt3", "alt4"
+- input-schmitt-enable:		No arguments. Enable schmitt-trigger mode.
+- input-schmitt-disable:	No arguments. Disable schmitt-trigger mode.
+- bias-pull-up:			No arguments. Pull up on pin.
+- bias-pull-down:		No arguments. Pull down on pin.
+- bias-disable:			No arguments. Disable pin bias.
+- slew-rate:			Integer. Meaning depends on configured pin mux:
+				*_SCL or *_SDA:
+					0: Standard(100kbps)& Fast(400kbps) mode
+					1: Highspeed (3.4Mbps) mode
+				IC_DM or IC_DP:
+					0: normal slew rate
+					1: fast slew rate
+				Otherwise:
+					0: fast slew rate
+					1: normal slew rate
+- input-enable:			No arguements. Enable input (does not affect
+				output.)
+- input-disable:		No arguements. Disable input (does not affect
+				output.)
+- drive-strength:		Integer. Drive strength in mA.  Valid values are
+				2, 4, 6, 8, 10, 12, 14, 16 mA.
+
+Optional Properties (for I2C pins):
+
+- function:			String. Specifies the pin mux selection. Values
+				must be one of: "alt1", "alt2", "alt3", "alt4"
+- bias-pull-up:			Integer. Pull up strength in Ohm. There are 3
+				pull-up resisitors (1.2k, 1.8k, 2.7k) available
+				in parallel for I2C pins, so the valid values
+				are: 568, 720, 831, 1080, 1200, 1800, 2700 Ohm.
+- bias-disable:			No arguments. Disable pin bias.
+- slew-rate:			Integer. Meaning depends on configured pin mux:
+				*_SCL or *_SDA:
+					0: Standard(100kbps)& Fast(400kbps) mode
+					1: Highspeed (3.4Mbps) mode
+				IC_DM or IC_DP:
+					0: normal slew rate
+					1: fast slew rate
+				Otherwise:
+					0: fast slew rate
+					1: normal slew rate
+- input-enable:			No arguements. Enable input (does not affect
+				output.)
+- input-disable:		No arguements. Disable input (does not affect
+				output.)
+
+Optional Properties (for HDMI pins):
+
+- function:			String. Specifies the pin mux selection. Values
+				must be one of: "alt1", "alt2", "alt3", "alt4"
+- slew-rate:			Integer. Controls slew rate.
+					0: Standard(100kbps)& Fast(400kbps) mode
+					1: Highspeed (3.4Mbps) mode
+- input-enable:			No arguements. Enable input (does not affect
+				output.)
+- input-disable:		No arguements. Disable input (does not affect
+				output.)
+
+Example:
+// pin controller node
+pinctrl@35004800 {
+	compatible = "brcm,capri-pinctrl";
+	reg = <0x35004800 0x430>;
+
+	// pin configuration node
+	dev_a_default: dev_a_active {
+		//group node defining 1 standard pin
+		grp_1 {
+			pins		= "std_pin1";
+			function	= "alt1";
+			input-schmitt-enable;
+			bias-disable;
+			slew-rate	= <1>;
+			drive-strength	= <4>;
+		};
+
+		// group node defining 2 I2C pins
+		grp_2 {
+			pins		= "i2c_pin1", "i2c_pin2";
+			function	= "alt2";
+			bias-pull-up	= <720>;
+			input-enable;
+		};
+
+		// group node defining 2 HDMI pins
+		grp_3 {
+			pins		= "hdmi_pin1", "hdmi_pin2";
+			function	= "alt3";
+			slew-rate	= <1>;
+		};
+
+		// other pin group nodes
+		...
+	};
+
+	// other pin configuration nodes
+	...
+};
+
+In the example above, "dev_a_active" is a pin configuration node with a number
+of sub-nodes.  In the pin group node "grp_1", one pin, "std_pin1", is defined in
+the "pins" property.  Thus, the remaining properties in the "grp_1" node applies
+only to this pin, including the following settings:
+ - setting pinmux to "alt1"
+ - enabling schmitt-trigger (hystersis) mode
+ - disabling pin bias
+ - setting the slew-rate to 1
+ - setting the drive strength to 4 mA
+Note that neither "input-enable" nor "input-disable" was specified - the pinctrl
+subsystem will therefore leave this property unchanged from whatever state it
+was in before applying these changes.
+
+The "pins" property in the pin group node "grp_2" specifies two pins -
+"i2c_pin1" and "i2c_pin2"; the remaining properties in this pin group node,
+therefore, applies to both of these pins.  The properties include:
+ - setting pinmux to "alt2"
+ - setting pull-up resistance to 720 Ohm (ie. enabling 1.2k and 1.8k resistors
+   in parallel)
+ - enabling both pins' input
+"slew-rate" is not specified in this pin group node, so the slew-rate for these
+pins are left as-is.
+
+Finally, "grp_3" defines two HDMI pins.  The following properties are applied to
+both pins:
+ - setting pinmux to "alt3"
+ - setting slew-rate to 1; for HDMI pins, this corresponds to the 3.4 Mbps
+   Highspeed mode
+The input is neither enabled or disabled, and is left untouched.
