+* Freescale IOMUX Controller (IOMUXC) for i.MX
+
+The IOMUX Controller (IOMUXC), together with the IOMUX, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called ALT modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the IOMUXC controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Freescale IMX pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'mux' selects the function mode(also named mux
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, open drain, drive strength, etc.
+
+Required properties for iomux controller:
+- compatible: "fsl,<soc>-iomuxc"
+  Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- fsl,pins: two integers array, represents a group of pins mux and config
+  setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
+  pin working on a specific function, CONFIG is the pad setting value like
+  pull-up on this pin. Please refer to fsl,<soc>-pinctrl.txt for the valid
+  pins and functions of each SoC.
+
+Bits used for CONFIG:
+NO_PAD_CTL(1 << 31): indicate this pin does not need config.
+
+SION(1 << 30): Software Input On Field.
+Force the selected mux mode input path no matter of MUX_MODE functionality.
+By default the input path is determined by functionality of the selected
+mux mode (regular).
+
+Other bits are used for PAD setting.
+Please refer to each fsl,<soc>-pinctrl,txt binding doc for SoC specific part
+of bits definitions.
+
+NOTE:
+Some requirements for using fsl,imx-pinctrl binding:
+1. We have pin function node defined under iomux controller node to represent
+   what pinmux functions this SoC supports.
+2. The pin configuration node intends to work on a specific function should
+   to be defined under that specific function node.
+   The function node's name should represent well about what function
+   this group of pins in this pin configuration node are working on.
+3. The driver can use the function node's name and pin configuration node's
+   name describe the pin function and group hierarchy.
+   For example, Linux IMX pinctrl driver takes the function node's name
+   as the function name and pin configuration node's name as group name to
+   create the map table.
+4. Each pin configuration node should have a phandle, devices can set pins
+   configurations by referring to the phandle of that pin configuration node.
+
+Examples:
+usdhc@0219c000 { /* uSDHC4 */
+	fsl,card-wired;
+	vmmc-supply = <&reg_3p3v>;
+	status = "okay";
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_usdhc4_1>;
+};
+
+iomuxc@020e0000 {
+	compatible = "fsl,imx6q-iomuxc";
+	reg = <0x020e0000 0x4000>;
+
+	/* shared pinctrl settings */
+	usdhc4 {
+		pinctrl_usdhc4_1: usdhc4grp-1 {
+			fsl,pins = <1386 0x17059	/* MX6Q_PAD_SD4_CMD__USDHC4_CMD */
+				    1392 0x10059	/* MX6Q_PAD_SD4_CLK__USDHC4_CLK	*/

+				    1517 0x17059>;	/* MX6Q_PAD_SD4_DAT7__USDHC4_DAT7 */
+		};
+	};
+	....
+};
+Refer to the IOMUXC controller chapter in imx6q datasheet,
+0x17059 means enable hysteresis, 47KOhm Pull Up, 50Mhz speed,
+80Ohm driver strength and Fast Slew Rate.
+User should refer to each SoC spec to set the correct value.
+
+TODO: when dtc macro support is available, we can change above raw data
+to dt macro which can get better readability in dts file.

+* Freescale MXS Pin Controller
+
+The pins controlled by mxs pin controller are organized in banks, each bank
+has 32 pins.  Each pin has 4 multiplexing functions, and generally, the 4th
+function is GPIO.  The configuration on the pins includes drive strength,
+voltage and pull-up.
+
+Required properties:
+- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
+- reg: Should contain the register physical address and length for the
+  pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+The node of mxs pin controller acts as a container for an arbitrary number of
+subnodes.  Each of these subnodes represents some desired configuration for
+a group of pins, and only affects those parameters that are explicitly listed.
+In other words, a subnode that describes a drive strength parameter implies no
+information about pull-up. For this reason, even seemingly boolean values are
+actually tristates in this binding: unspecified, off, or on. Unspecified is
+represented as an absent property, and off/on are represented as integer
+values 0 and 1.
+
+Those subnodes under mxs pin controller node will fall into two categories.
+One is to set up a group of pins for a function, both mux selection and pin
+configurations, and it's called group node in the binding document.   The other
+one is to adjust the pin configuration for some particular pins that need a
+different configuration than what is defined in group node.  The binding
+document calls this type of node config node.
+
+On mxs, there is no hardware pin group. The pin group in this binding only
+means a group of pins put together for particular peripheral to work in
+particular function, like SSP0 functioning as mmc0-8bit.  That said, the
+group node should include all the pins needed for one function rather than
+having these pins defined in several group nodes.  It also means each of
+"pinctrl-*" phandle in client device node should only have one group node
+pointed in there, while the phandle can have multiple config node referenced
+there to adjust configurations for some pins in the group.
+
+Required subnode-properties:
+- fsl,pinmux-ids: An integer array.  Each integer in the array specify a pin
+  with given mux function, with bank, pin and mux packed as below.
+
+    [15..12] : bank number
+    [11..4]  : pin number
+    [3..0]   : mux selection
+
+  This integer with mux selection packed is used as an entity by both group
+  and config nodes to identify a pin.  The mux selection in the integer takes
+  effects only on group node, and will get ignored by driver with config node,
+  since config node is only meant to set up pin configurations.
+
+  Valid values for these integers are listed below.
+
+- reg: Should be the index of the group nodes for same function.  This property
+  is required only for group nodes, and should not be present in any config
+  nodes.
+
+Optional subnode-properties:
+- fsl,drive-strength: Integer.
+    0: 4 mA
+    1: 8 mA
+    2: 12 mA
+    3: 16 mA
+- fsl,voltage: Integer.
+    0: 1.8 V
+    1: 3.3 V
+- fsl,pull-up: Integer.
+    0: Disable the internal pull-up
+    1: Enable the internal pull-up
+
+Examples:
+
+pinctrl@80018000 {
+	#address-cells = <1>;
+	#size-cells = <0>;
+	compatible = "fsl,imx28-pinctrl";
+	reg = <0x80018000 2000>;
+
+	mmc0_8bit_pins_a: mmc0-8bit@0 {
+		reg = <0>;
+		fsl,pinmux-ids = <
+			0x2000 0x2010 0x2020 0x2030
+			0x2040 0x2050 0x2060 0x2070
+			0x2080 0x2090 0x20a0>;
+		fsl,drive-strength = <1>;
+		fsl,voltage = <1>;
+		fsl,pull-up = <1>;
+	};
+
+	mmc_cd_cfg: mmc-cd-cfg {
+		fsl,pinmux-ids = <0x2090>;
+		fsl,pull-up = <0>;
+	};
+
+	mmc_sck_cfg: mmc-sck-cfg {
+		fsl,pinmux-ids = <0x20a0>;
+		fsl,drive-strength = <2>;
+		fsl,pull-up = <0>;
+	};
+};
+
+In this example, group node mmc0-8bit defines a group of pins for mxs SSP0
+to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations
+applied on all these pins.  And config nodes mmc-cd-cfg and mmc-sck-cfg are
+adjusting the configuration for pins card-detection and clock from what group
+node mmc0-8bit defines.  Only the configuration properties to be adjusted need
+to be listed in the config nodes.

+NVIDIA Tegra20 pinmux controller
+
+Required properties:
+- compatible: "nvidia,tegra20-pinmux"
+- reg: Should contain the register physical address and length for each of
+  the tri-state, mux, pull-up/down, and pad control register sets.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Tegra's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, tristate, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function or tristate parameter. For this
+reason, even seemingly boolean values are actually tristates in this binding:
+unspecified, off, or on. Unspecified is represented as an absent property,
+and off/on are represented as integer values 0 and 1.
+
+Required subnode-properties:
+- nvidia,pins : An array of strings. Each string contains the name of a pin or
+    group. Valid values for these names are listed below.
+
+Optional subnode-properties:
+- nvidia,function: A string containing the name of the function to mux to the
+  pin or group. Valid values for function names are listed below. See the Tegra
+  TRM to determine which are valid for each pin or group.
+- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
+    0: none, 1: down, 2: up.
+- nvidia,tristate: Integer.
+    0: drive, 1: tristate.
+- nvidia,high-speed-mode: Integer. Enable high speed mode the pins.
+    0: no, 1: yes.
+- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
+    0: no, 1: yes.
+- nvidia,low-power-mode: Integer. Valid values 0-3. 0 is least power, 3 is
+    most power. Controls the drive power or current. See "Low Power Mode"
+    or "LPMD1" and "LPMD0" in the Tegra TRM.
+- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
+    The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
+    Tegra TRM.
+- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
+    The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
+    Tegra TRM.
+- nvidia,slew-rate-rising: Integer. Controls rising signal slew rate. 0 is
+    fastest. The range of valid values depends on the pingroup. See
+    "DRVDN_SLWR" in the Tegra TRM.
+- nvidia,slew-rate-falling: Integer. Controls falling signal slew rate. 0 is
+    fastest. The range of valid values depends on the pingroup. See
+    "DRVUP_SLWF" in the Tegra TRM.
+
+Note that many of these properties are only valid for certain specific pins
+or groups. See the Tegra TRM and various pinmux spreadsheets for complete
+details regarding which groups support which functionality. The Linux pinctrl
+driver may also be a useful reference, since it consolidates, disambiguates,
+and corrects data from all those sources.
+
+Valid values for pin and group names are:
+
+  mux groups:
+
+    These all support nvidia,function, nvidia,tristate, and many support
+    nvidia,pull.

+NVIDIA Tegra30 pinmux controller
+
+The Tegra30 pinctrl binding is very similar to the Tegra20 pinctrl binding,
+as described in nvidia,tegra20-pinmux.txt. In fact, this document assumes
+that binding as a baseline, and only documents the differences between the
+two bindings.
+
+Required properties:
+- compatible: "nvidia,tegra30-pinmux"
+- reg: Should contain the register physical address and length for each of
+  the pad control and mux registers.
+
+Tegra30 adds the following optional properties for pin configuration subnodes:
+- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
+- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
+- nvidia,lock: Integer. Lock the pin configuration against further changes
+    until reset. 0: no, 1: yes.
+- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
+
+As with Tegra20, see the Tegra TRM for complete details regarding which groups
+support which functionality.
+
+Valid values for pin and group names are:
+
+  per-pin mux groups:
+
+    These all support nvidia,function, nvidia,tristate, nvidia,pull,
+    nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
+    nvidia,io-reset.

+== Introduction ==
+
+Hardware modules that control pin multiplexing or configuration parameters
+such as pull-up/down, tri-state, drive-strength etc are designated as pin
+controllers. Each pin controller must be represented as a node in device tree,
+just like any other hardware module.
+
+Hardware modules whose signals are affected by pin configuration are
+designated client devices. Again, each client device must be represented as a
+node in device tree, just like any other hardware module.
+
+For a client device to operate correctly, certain pin controllers must
+set up certain specific pin configurations. Some client devices need a
+single static pin configuration, e.g. set up during initialization. Others
+need to reconfigure pins at run-time, for example to tri-state pins when the
+device is inactive. Hence, each client device can define a set of named
+states. The number and names of those states is defined by the client device's
+own binding.
+
+The common pinctrl bindings defined in this file provide an infrastructure
+for client device device tree nodes to map those state names to the pin
+configuration used by those states.
+
+Note that pin controllers themselves may also be client devices of themselves.
+For example, a pin controller may set up its own "active" state when the
+driver loads. This would allow representing a board's static pin configuration
+in a single place, rather than splitting it across multiple client device
+nodes. The decision to do this or not somewhat rests with the author of
+individual board device tree files, and any requirements imposed by the
+bindings for the individual client devices in use by that board, i.e. whether
+they require certain specific named states for dynamic pin configuration.
+
+== Pinctrl client devices ==
+
+For each client device individually, every pin state is assigned an integer
+ID. These numbers start at 0, and are contiguous. For each state ID, a unique
+property exists to define the pin configuration. Each state may also be
+assigned a name. When names are used, another property exists to map from
+those names to the integer IDs.
+
+Each client device's own binding determines the set of states the must be
+defined in its device tree node, and whether to define the set of state
+IDs that must be provided, or whether to define the set of state names that
+must be provided.
+
+Required properties:
+pinctrl-0:	List of phandles, each pointing at a pin configuration
+		node. These referenced pin configuration nodes must be child
+		nodes of the pin controller that they configure. Multiple
+		entries may exist in this list so that multiple pin
+		controllers may be configured, or so that a state may be built
+		from multiple nodes for a single pin controller, each
+		contributing part of the overall configuration. See the next
+		section of this document for details of the format of these
+		pin configuration nodes.
+
+		In some cases, it may be useful to define a state, but for it
+		to be empty. This may be required when a common IP block is
+		used in an SoC either without a pin controller, or where the
+		pin controller does not affect the HW module in question. If
+		the binding for that IP block requires certain pin states to
+		exist, they must still be defined, but may be left empty.
+
+Optional properties:
+pinctrl-1:	List of phandles, each pointing at a pin configuration
+		node within a pin controller.
+...
+pinctrl-n:	List of phandles, each pointing at a pin configuration
+		node within a pin controller.
+pinctrl-names:	The list of names to assign states. List entry 0 defines the
+		name for integer state ID 0, list entry 1 for state ID 1, and
+		so on.
+
+For example:
+
+	/* For a client device requiring named states */
+	device {
+		pinctrl-names = "active", "idle";
+		pinctrl-0 = <&state_0_node_a>;
+		pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+	};
+
+	/* For the same device if using state IDs */
+	device {
+		pinctrl-0 = <&state_0_node_a>;
+		pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+	};
+
+	/*
+	 * For an IP block whose binding supports pin configuration,
+	 * but in use on an SoC that doesn't have any pin control hardware
+	 */
+	device {
+		pinctrl-names = "active", "idle";
+		pinctrl-0 = <>;
+		pinctrl-1 = <>;
+	};
+
+== Pin controller devices ==
+
+Pin controller devices should contain the pin configuration nodes that client
+devices reference.
+
+For example:
+
+	pincontroller {
+		... /* Standard DT properties for the device itself elided */
+
+		state_0_node_a {
+			...
+		};
+		state_1_node_a {
+			...
+		};
+		state_1_node_b {
+			...
+		};
+	}
+
+The contents of each of those pin configuration child nodes is defined
+entirely by the binding for the individual pin controller device. There
+exists no common standard for this content.
+
+The pin configuration nodes need not be direct children of the pin controller
+device; they may be grandchildren, for example. Whether this is legal, and
+whether there is any interaction between the child and intermediate parent
+nodes, is again defined entirely by the binding for the individual pin
+controller device.

+SPEAr's pinmux nodes act as a container for an abitrary number of subnodes. Each
+of these subnodes represents muxing for a pin, a group, or a list of pins or
+groups.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Required subnode-properties:
+- st,pins : An array of strings. Each string contains the name of a pin or
+  group.
+- st,function: A string containing the name of the function to mux to the pin or
+  group. See the SPEAr's TRM to determine which are valid for each pin or group.
+
+  Valid values for group and function names can be found from looking at the
+  group and function arrays in driver files:
