Hi Linus,

this is the bulk of the GPIO changes for the v4.11 kernel cycle.
The details are in the signed tag as usual. Here some merge mechanics:

- As expected an immutable branch with changes shared with the pin
control subsystem was pulled into the GPIO tree as well, making a slew
of changes appear in drivers/pinctrl also in this pull request. The hashes
are the same, all should be fine.

- The above leads to a conflict with the staging tree greybus GPIO
driver in drivers/staging/greybus/gpio.c where a checkpatch fix was
clashing with the changes.
Stephen has a resolution in the next tree.

- A bunch of tree-wide changes updating the illogically named fwnode_*
accessors and adding flags was merged hitting sites in
drivers/input/keyboard/gpio_keys*
drivers/leds/leds-gpio.c
drivers/video/fbdev/amba-clcd-nomadik.c
Oh well no more sites than that needed to be changed. And the changes
are ACKed.

- The above leads to a merge problem where the TTY/serial tree adds
a new user of these APIs in drivers/tty/serial/st-asc.c
Oh well, things like that cannot be totally avoided.
Depending on which tree gets merged first this leads to a build regression.
Stephen has a resolution in the next tree.
"serial: st-asc: merge fix for devm_get_gpiod_from_child rename"

I guess the above conflicts could have been avoided by being more helpful
to point out to Greg that he could pull in the immutable branches to serial and
staging, sorry about that :(

Apart from this it should be fine.

Please pull it in!

Yours,
Linus Walleij

The following changes since commit 7ce7d89f48834cefece7804d38fc5d85382edf77:

gpio: pci-idio-16: Fix PCI BAR index (2017-02-13 16:19:10 +0100)

----------------------------------------------------------------
This is the bulk of GPIO changes for the v4.11 cycle

Core changes:

- Augment fwnode_get_named_gpiod() to configure the GPIO pin
immediately after requesting it like all other APIs do.
This is a treewide change also updating all users.

- Pass a GPIO label down to gpiod_request() from
fwnode_get_named_gpiod(). This makes debugfs and the userspace
ABI correctly reflect the current in-kernel consumer of a pin
taken using this abstraction. This is a treewide change also
updating all users.

- Rename devm_get_gpiod_from_child() to
devm_fwnode_get_gpiod_from_child() to reflect the fact that this
function is operating on a fwnode object. This is a treewide
change also updating all users.

- Make it possible to take multiple GPIOs in a single hog of device
tree hogs.

- The refactorings switching GPIO chips to use the .set_config()
callback using standard pin control properties and providing
a backend into the pin control subsystem that were also merged
into the pin control tree naturally appear here too.

Testing instrumentation:

- A whole slew of cleanups and improvements to the mockup GPIO
driver. We now have an extended userspace test exercising the
subsystem, and we can inject interrupts etc from userspace
to fully test the core GPIO functionality.

New drivers:

- New driver for the Cortina Systems Gemini GPIO controller.

- New driver for the Exar XR17V352/354/358 chips.

- New driver for the ACCES PCI-IDIO-16 PCI GPIO card.

Driver changes:

- RCAR: set the irqchip parent device, add fine-grained runtime
PM support.

- pca953x: support optional RESET control line on the chip.

- DaVinci: cleanups and simplifications. Add support for multiple
instances.

- .set_multiple() and naming of lines on more or less all of the
ISA/PCI GPIO controllers.

- mcp23s08: refactored to use regmap as a first step to further
rewrites and modernizations.
