The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.
Search and update was done with coccinelle and the invaluable help of
Julia Lawall.

Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs,
which uses the Qualcomm Technologies TLMM pinctrl/gpio device. This
driver is probed via ACPI and uses the pinctrl-msm.c backend driver.
This driver is intended to be used only an ACPI-enabled system. As such,
UEFI will handle all pin control configuration, so this driver does not
provide pin control functions. It is effectively a GPIO-only driver.

The "function" of the MPP driver was inherited from the GPIO driver, but the
differences between the two hardware blocks makes both the driver and the
device tree binding to be awkward.
Instead of overloading the "normal" function with various modes this patch
transposes the pinmux function to represent the three operating modes of the
MPP (digital, analog and current sink). The properties of pin pairing and DTEST
routing is moved to separate properties.

Assign pm_power_off() if we have the PS_HOLD functionality so
that we can properly shutdown the SoC. Otherwise, shutdown won't
do anything besides put the CPU into a tight loop. Unfortunately,
we have to use a singleton here because pm_power_off() doesn't
take any arguments. Fortunately there's only one instance of the
pinctrl device on a running system so this isn't a problem.

There's currently no way to re-enable a mpp block once you've entered a state
that disables the state, this patch makes it possible to leave the
bias-high-impedance state.
Also read the enable state from the hardware on probe.
With this in place the is_enabled variable is accurately tracking the state of
the hardware and we can use that for the debug output as well.

Pull pin control updates from Linus Walleij:
"Here is the bulk of pin control changes for the v4.2 series: Quite a
lot of new SoC subdrivers and two new main drivers this time, apart
from that business as usual.
Details:
Core functionality:
- Enable exclusive pin ownership: it is possible to flag a pin
controller so that GPIO and other functions cannot use a single pin
simultaneously.
New drivers:
- NXP LPC18xx System Control Unit pin controller
- Imagination Pistachio SoC pin controller
New subdrivers:
- Freescale i.MX7d SoC
- Intel Sunrisepoint-H PCH
- Renesas PFC R8A7793
- Renesas PFC R8A7794
- Mediatek MT6397, MT8127
- SiRF Atlas 7
- Allwinner A33
- Qualcomm MSM8660
- Marvell Armada 395
- Rockchip RK3368
Cleanups:
- A big cleanup of the Marvell MVEBU driver rectifying it to
correspond to reality
- Drop platform device probing from the SH PFC driver, we are now a
DT only shop for SuperH
- Drop obsolte multi-platform check for SH PFC
- Various janitorial: constification, grammar etc
Improvements:
- The AT91 GPIO portions now supports the set_multiple() feature
- Split out SPI pins on the Xilinx Zynq
- Support DTs without specific function nodes in the i.MX driver"

Currently, pinctrl_register() just returns NULL on error, so the
callers can not know the exact reason of the failure.
Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some
-ENOMEM on error of pinctrl_register(), although the error code
might be different from the real cause of the error.
This commit reworks pinctrl_register() to return the appropriate
error code and modifies all of the pinctrl drivers to use IS_ERR()
for the error checking and PTR_ERR() for getting the error code.

The zynq and qcom-spmi pinctrl drivers both use pin_config_item arrays
to provide extra interfaces in debugfs. This structure and the
PCONFDUMP macro are not defined if CONFIG_DEBUG_FS is turned off,
so we get build errors like:
pinctrl/qcom/pinctrl-spmi-gpio.c:139:37: error: array type has incomplete element type
static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = {

static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = {
Lacking any better idea to solve this nicely, this patch uses #ifdef
to hide the structures, just like the pinctrl core does.

Pull GPIO changes from Linus Walleij:
"This is the bulk of GPIO changes for the v3.18 development cycle:
- Increase the default ARCH_NR_GPIO from 256 to 512. This was done
to avoid having a custom <asm/gpio.h> header for the x86
architecture - GPIO is custom and complicated enough as it is
already! We want to move to a radix to store the descriptors going
forward, and finally get rid of this fixed array size altogether.
- Endgame patching of the gpio_remove() semantics initiated by
Abdoulaye Berthe. It is not accepted by the system that the
removal of a GPIO chip fails during eg reboot or shutdown, and
therefore the return value has now painfully been refactored away.
For special cases like GPIO expanders on a hot-pluggable bus like
USB, we may later add some gpiochip_try_remove() call, but for the
cases we have now, return values are moot.
- Some incremental refactoring of the gpiolib core and ACPI GPIO
library for more descriptor usage.
- Refactor the chained IRQ handler set-up method to handle also
threaded, nested interrupts and set up the parent IRQ correctly.
Switch STMPE and TC3589x drivers to use this registration method.
- Add a .irq_not_threaded flag to the struct gpio_chip, so that also
GPIO expanders that block but are still not using threaded IRQ
handlers.
- New drivers for the ARM64 X-Gene SoC GPIO controller.
- The syscon GPIO driver has been improved to handle the "DSP GPIO"
found on the TI Keystone 2 SoC:s.
- ADNP driver switched to use gpiolib irqchip helpers.
- Refactor the DWAPB driver to support being instantiated from and

case where PS_HOLD has failed to reset the chip.
Since this mechanism may be one of several mechanisms registered, change

of 10 seconds.
Choose priority 128, as according to documentation, this mechanism "is
sufficient to restart the entire system".

But the new APQ8084 SoC uses a different value. To resolve this, we make

to use the current value, and only for APQ8084 we use the new value.

This patchset adds pinctrl support for the Qualcomm APQ8084 platform.
This set of patches adds pinctrl support for the Qualcomm APQ8084 platform.
The first patch adds the pin definitions. The second patch contains the
devicetree binding documentation. The third patch adds the DT node.
The last patch makes the INTR_TARGET_PROC_APPS value configurable and
defines it for each existing SoC.
Tested on IFC6540 board.
Changes since v3:
- Fixed the sdc valid pin values in the binding documentation - sdc2
instead of sdc3. (suggested by Bjorn Andersson)
Changes since v2:
- Fixed some incorrect bits and offsets. (suggested by Bjorn Andersson)
- Updated binding documentation to follow the format of msm8960.
(suggested by Bjorn Andersson)
- Added fourth patch, which removes the hardcoded INTR_TARGET_PROC_APPS
value and makes it configurable. Also we keep the current value for
existing SoCs. (suggested by Bjorn Andersson)
Changes since v1:
- Updated the total number of pins (suggested by Bjorn Andersson)
- Added the missing pin info (provided by Andy Gross)
- Updated groups and functions to be consistent with other pinctrls.
(suggested by Andy Gross)
- Removed unused functions, qdss and test pins. (suggested by Andy Gross)
- Updated the documentation with the possible functions.

commit 2243a87d90b42eb38bc281957df3e57c712b5e56
"pinctrl: avoid duplicated calling enable_pinmux_setting for a pin"
removed the .disable callback from the struct pinmux_ops,
making the .enable() callback the only remaining callback.
However .enable() is a bad name as it seems to imply that a
muxing can also be disabled. Rename the callback to .set_mux()
and also take this opportunity to clean out any remaining
mentions of .disable() from the documentation.
