Pull bulk pin control changes from Linus Walleij:
 "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

   - New driver for the Qualcomm TLMM pin controller and its msm8x74
     subdriver.

   - New driver for the Broadcom Capri BCM281xx SoC.

   - New subdriver for the imx25 pin controller.

   - New subdriver for the Tegra124 pin controller.

   - Lock GPIO lines as IRQs for select combined pin control and GPIO
     drivers for baytrail and sirf.

   - Some semi-big refactorings and extenstions to the sirf driver.

   - Lots of patching, cleanup and fixing in the Renesas "PFC" driver
     and associated subdrivers as usual.  It is settling down a little
     bit now it seems.

   - Minor fixes and incremental updates here and there as usual"

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:

per-pin mux groups:

These all support nvidia,function, nvidia,tristate, nvidia,pull,
nvidia,enable-input. Some support nvidia,lock nvidia,open-drain,
nvidia,io-reset and nvidia,rcv-sel.

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

(Note that this is not yet the complete list of functions)

msmgpio: pinctrl@fd510000 {
compatible = "qcom,msm8974-pinctrl";
reg = <0xfd510000 0x4000>;
