 "This has been queued and tested for a while.  Lots of action here,
  like in the GPIO tree, embedded stuff like this is really hot now it
  seems.  Details in the signed tag.  I'm especially happy about the
  Qualcomm driver as it is used in such a huge subset of mobile handsets
  out there, and these platforms in general need better upstream support

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.

NVIDIA Tegra124 pinmux controller
The Tegra124 pinctrl binding is very similar to the Tegra20 and Tegra30
pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
nvidia,tegra30-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,tegra124-pinmux"
- reg: Should contain a list of base address and size pairs for:
-- first entry - the drive strength and pad control registers.
-- second entry - the pinmux registers
Tegra124 adds the following optional properties for pin configuration subnodes.
The macros for options are defined in the
include/dt-binding/pinctrl/pinctrl-tegra.h.
- nvidia,enable-input: Integer. Enable the pin's input path.
enable :TEGRA_PIN_ENABLE0 and
disable or output only: TEGRA_PIN_DISABLE.
- nvidia,open-drain: Integer.
enable: TEGRA_PIN_ENABLE.
disable: TEGRA_PIN_DISABLE.
- nvidia,lock: Integer. Lock the pin configuration against further changes
until reset.
enable: TEGRA_PIN_ENABLE.
disable: TEGRA_PIN_DISABLE.
- nvidia,io-reset: Integer. Reset the IO path.
enable: TEGRA_PIN_ENABLE.
disable: TEGRA_PIN_DISABLE.
- nvidia,rcv-sel: Integer. Select VIL/VIH receivers.
normal: TEGRA_PIN_DISABLE
high: TEGRA_PIN_ENABLE
Please refer the Tegra TRM for complete details regarding which groups
support which functionality.
Valid values for pin and group names are:

Qualcomm MSM8974 TLMM block
Required properties:
- compatible: "qcom,msm8x74-pinctrl"
- reg: Should be the base address and length of the TLMM block.
- interrupts: Should be the parent IRQ of the TLMM block.
- interrupt-controller: Marks the device node as an interrupt controller.
- #interrupt-cells: Should be two.
- gpio-controller: Marks the device node as a GPIO controller.
- #gpio-cells : Should be two.
The first cell is the gpio pin number and the
second cell is used for optional parameters.
Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
a general description of GPIO and interrupt bindings.
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".
Qualcomm'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, 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.
The following generic properties as defined in pinctrl-bindings.txt are valid
to specify in a pin configuration subnode:
pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength.
Non-empty subnodes must specify the 'pins' property.
Note that not all properties are valid for all pins.
Valid values for qcom,pins are:
gpio0-gpio145
Supports mux, bias and drive-strength
sdc1_clk, sdc1_cmd, sdc1_data, sdc2_clk, sdc2_cmd, sdc2_data
Supports bias and drive-strength
Valid values for qcom,function are:
blsp_i2c2, blsp_i2c6, blsp_i2c11, blsp_spi1, blsp_uart2, blsp_uart8, slimbus

/* For dual-edge interrupts in software, since some hardware has no
* such support:
*
* At appropriate moments, this function may be called to flip the polarity
* settings of both-edge irq lines to try and catch the next edge.
*
* The attempt is considered successful if:
* - the status bit goes high, indicating that an edge was caught, or
* - the input value of the gpio doesn't change during the attempt.
* If the value changes twice during the process, that would cause the first
* test to fail but would force the second, as two opposite
* transitions would cause a detection no matter the polarity setting.
*
* The do-loop tries to sledge-hammer closed the timing hole between
* the initial value-read and the polarity-write - if the line value changes
* during that window, an interrupt is lost, the new polarity setting is
* incorrect, and the first success test will fail, causing a retry.
*
* Algorithm comes from Google's msmgpio driver.
