Merge commit '70c8f01a' into dt3-base 

This is a commit from the for-next branch of Linus Walleij's pin control tre
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git

It is the oldest commit in that branch that provides the dependencies
needed for SoC changes to the usage of sh-pfc.

CONFIG can be 0 or 1, meaning Pullup disable/enable.
The iomux controller has gpio child nodes which are embedded in the iomux
control registers. They have to be defined as child nodes of the iomux device
node. If gpio subnodes are defined "#address-cells", "#size-cells" and "ranges"
properties for the iomux device node are required.

Qualcomm MSM8x74 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)
Example:
msmgpio: pinctrl@fd510000 {
compatible = "qcom,msm8x74-pinctrl";
reg = <0xfd510000 0x4000>;
gpio-controller;
#gpio-cells = <2>;
interrupt-controller;
#interrupt-cells = <2>;
interrupts = <0 208 0>;
pinctrl-names = "default";
pinctrl-0 = <&uart2_default>;
uart2_default: uart2_default {
mux {
qcom,pins = "gpio4", "gpio5";
qcom,function = "blsp_uart2";
};
tx {
qcom,pins = "gpio4";
drive-strength = <4>;
bias-disable;
};
rx {
qcom,pins = "gpio5";

*
* 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.
