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.
- I have added an API preserving fix to keep the new ST serial driver
compiling and will iron out the API change in -rc2 or so. All should be
fine, Greg suggested this fix and test merges+builds confirm
it works smooth.
- Changes to other subsystems have been ACKed and a test merge
confirmed all is merging cleanly this morning to your tree.
Please pull it in!
Yours,
Linus Walleij

gpio: reintroduce devm_get_gpiod_from_child() (2017-02-21 14:19:45 +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.
