* 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 */
1462 0x17059 /* MX6Q_PAD_SD4_DAT0__USDHC4_DAT0 */

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.

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:
drivers/pinctrl/spear/pinctrl-spear3*0.c
