Hi Linus,
here is the bulk of GPIO changes for v4.20. Lots of changes
this time, all good stuff, the details are in the signed tag
as usual. They have all boiled in linux-next as is custom.
Some merge mechanics:
- The Ingenic driver was moved over to pin control as mentioned
in my pin control pull request and these commits naturally
appear here as well.
- Some single patches affecting arch/arm, drivers/mmc,
drivers/bus and drivers/auxdisplay
are here because of dependencies, and those have been ACKed
by respective subsystem maintainer.
- One patch hits arch/x86/platform/ts5500/ts5500.c
was augmented and I have requested comments from the
maintainers. They seem to be unresponsive for close to 2
months (patch sent august 29) so the patch is applied anyway.
It's no big change anyway.
Please pull it in!
Yours,
Linus Walleij

gpio: Clarify kerneldoc on gpiochip_set_chained_irqchip()
(2018-10-16 09:30:22 +0200)
----------------------------------------------------------------
This is the bulk of GPIO changes for the v4.20 series:
Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO
lines as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can
use only the fastpatch callbacks to enable/disable irqs
like any normal irqchip, especially the gpiod_lock_as_irq()
has been improved to be callable in fastpath context.
A bunch of rework had to be done to achieve this but it is
a big win since I never liked to restrict this to slowpath.
The only call requireing slowpath was try_module_get() and
this is kept at the .request_resources() slowpath callback.
In the GPIO CEC driver this is a big win sine a single
line is used for both outgoing and incoming traffic, and
this needs to use IRQs for incoming traffic while actively
driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a
"cookie" (struct gpio_array) and a bitmap for setting or
getting multiple GPIO lines at once. This improvement
orginated in a specific need to speed up an OMAP1 driver and
has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot
of checks and code when we want things to go really fast.
The previous code would minimize the number of calls
down to the driver callbacks assuming the CPU speed was
orders of magnitude faster than the I/O latency, but this
assumption was wrong on several platforms: what we needed
to do was to profile and improve the speed on the hot
path of the array functions and this change is now
completed.
- Clean out the painful and hard to grasp BNF experiments
from the device tree bindings. Future approaches are looking
into using JSON schema for this purpose. (Rob Herring
is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and
other contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin
control driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver.
