Subject[GIT PULL] bulk GPIO changes for v4.13
Hi Linus,

here is the big GPIO pull request for v4.13. The details
are in the signed tag as usual.

Some administrativa:

I have a slew of 8250 serial patches and the new IOT2040
serial+GPIO driver coming in through this tree, along with a
whole bunch of Exar 8250 fixes. These are ACKed by Greg
and also hit drivers/platform/* where they are ACKed by
Andy Shevchenko.

Speaking about drivers/platform/* there is also a bunch of
ACPI stuff coming through that route, again ACKed by Andy.

The MCP23S08 changes are coming in here as well. You already
have the commits in your tree, so this is just a result of sharing
an immutable branch between pin control and GPIO.

Then there is one merge conflict. I resisted pulling in a
release candidate to resolve it because I think that was
messy for no major reason. The conflict is in:

drivers/gpio/gpio-mvebu.c

<<<<<<< HEAD
writel_relaxed(set, mvebu_gpioreg_blink_counter_select(mvchip));
=======
regmap_write(mvchip->regs,
GPIO_BLINK_CNT_SELECT_OFF + mvchip->offset, 0);
>>>>>>> 65b69a94f4130143bfb8d4e995b875ae35d993f3

It should be resolved like this:

regmap_write(mvchip->regs,
GPIO_BLINK_CNT_SELECT_OFF + mvchip->offset, set);

So the second line with the "0" argument switched to "set".

It is a result of fixes on the rc's followed by a conversion to regmap
on the main development branch.

Apart from this it should all be fine.

Please pull it in!

Yours,
Linus Walleij

serial: exar: Add support for IOT2040 device (2017-07-03 08:33:20 +0200)

----------------------------------------------------------------
This is the bulk of GPIO changes for the v4.13 series:

Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO line
may loose its state during suspend/resume of the system to save
power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.

New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this
changeset.

Substantial driver changes:
- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.
- Serious cleanup and improvement of the mockup driver, giving us a
better test coverage.

Misc:
- Lots of janitorial clean up.
- A bunch of documentation fixes.
