Subject: [GIT PULL] GPIO bulk changes for the v4.15 kernel cycle
Hi Linus,
here is the bulk of GPIO changes for the v4.15 kernel cycle.
Conflicts ahoy!
There will be a conflict in drivers/pinctrl/bcm/pinctrl-bcm2835.c.
This one is a bit silly really, as Thierry developed the patches
on top of linux-next where his patches applied cleanly and then
I applied them on my v4.14-rc1-based tree and solved the
conflict. So since the conflicty thing was already upstream, maybe
I should have just merged in another -rc...
Anyway it looks like this:
++<<<<<<< HEAD
+ generic_handle_irq(irq_linear_revmap(pc->gpio_chip.irqdomain,
++=======
+ /* FIXME: no clue why the code looks up the type here */
+ type = pc->irq_type[gpio];
+
+ generic_handle_irq(irq_linear_revmap(pc->gpio_chip.irq.domain,
++>>>>>>> 24f0966c3e3f52a96e888504d60810d9df5b2d42
The end result should simply be: no comment, delete the type = business,
and keep that oneline:
generic_handle_irq(irq_linear_revmap(pc->gpio_chip.irq.domain,
Then Stepgen R reports a build-time conflict with changes from
the IRQchip core from the tip tree, requireing the following
fixup patch:

This patch should be available in linux-next.
The patch submitter has sent a similar patch.
I guess it's simple enough for you to either edit in or pick from
linux-next, or propose a line of fixing that fits better with your flow.
Those two should be all! I hope I didn't break anything else.
There is a patch hitting <linux/bitops.h> and it is ACKed by Andrew
Morton.
This also hits this file:
drivers/md/dm-mpath.c | 22 +-
Which is the siter where we factored out the nice little assign_bit()
function. It's nice to have this available globally.
Please pull this in and fix the above smallish things! (Or tell me what
else to do.)
Yours,
Linus Walleij

gpio: tegra186: Remove tegra186_gpio_lock_class (2017-11-13 11:43:10 +0100)
----------------------------------------------------------------
This is the bulk of GPIO changes for the v4.15 kernel cycle:
CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal
of dead code etc.
- Explicit comments on fall-through switch() statements.
