-Broadcom BCM281xx 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,bcm11351-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 at 35004800 {
-		compatible = "brcm,bcm11351-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 arguments. Enable input (does not affect
-				output.)
-- input-disable:		No arguments. 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 resistors (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 arguments. Enable input (does not affect
-				output.)
-- input-disable:		No arguments. 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 arguments. Enable input (does not affect
-				output.)
-- input-disable:		No arguments. Disable input (does not affect
-				output.)
-
-Example:
-// pin controller node
-pinctrl at 35004800 {
-	compatible = "brcm,bcm11351-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.
