Merge tag 'gpio-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.9 kernel cycle.

There is nothing too exciting in it, but a new macro that fixes a
build failure on a minor ARM32 platform that appeared yesterday is
part of it so we better merge it.

Core changes:

- Introduce the for_each_requested_gpio() macro to help in dependent
code all over the place. Also patch a few locations to use it while
we are at it.

- Split out the sysfs code into its own file.

- Split out the character device code into its own file, then make a
set of refactorings and improvements to this code. We are setting
the stage to revamp the userspace API a bit in the next cycle.

- Fix a whole slew of kerneldoc that was wrong or missing.

New drivers:

- The PCA953x driver now supports the PCAL9535.

Driver improvements:

- A host of incremental modernizations and improvements to the
PCA953x driver.

- Incremental improvements to the Xilinx Zynq driver.

- Some improvements to the GPIO aggregator driver.

- I ran all over the place switching all threaded and other drivers
requesting their own IRQ while using the core GPIO IRQ helpers to
pass the GPIO irq chip as a template instead of calling the
explicit set-up functions. Next merge window we may retire the old
code altogether"

gpiolib: cdev: use blocking notifier call chain instead of atomic

Replace usage of atomic_notifier_call_chain with
blocking_notifier_call_chain as the notifier function,
lineinfo_changed_notify, calls gpio_desc_to_lineinfo,
which calls pinctrl_gpio_can_use_line, which can sleep.

The chain isn't being called from an atomic context so the
the blocking notifier is a suitable substitute.

gpiolib: move gpiolib-sysfs function declarations into their own header

Move gpiolib-sysfs function declarations into their own header.

These functions are in gpiolib-sysfs.c, and are only required by gpiolib.c,
and so should be in a module header, not gpiolib.h.

This brings gpiolib-sysfs into line with gpiolib-cdev, and is another step
towards removing the sysfs inferface.

Merge tag 'gpio-v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.8 kernel cycle.

Core changes:

- A new GPIO aggregator driver has been merged: this can join a few
select GPIO lines into a new aggregated GPIO chip. This can be used
for security: a process can be granted access to only these lines,
for example for industrial control. Another way to use this is to
reexpose certain select lines to a virtual machine or container.

- Warn if the gpio-line-names is too long in he DT parser core.

- GPIO lines can now be looked up by line name in addition to being
looked up by offset.

New drivers:

- A new generic regmap GPIO driver has been merged. Too many regmap
drivers are starting to look like each other so we need to create
some common ground and try to move drivers over to using that.

- The F7188X driver now supports F81865.

Driver improvements:

- Large improvements to the PCA953x expander, get multiple lines and
several cleanups.

- Large improvements to the DesignWare DWAPB driver, and Sergey Semin
has volunteered to maintain it.

- PL061 can now be built as a module, this is part of a bigger effort
to make the ARM platforms more modular"
