[GIT PULL] Bulk GPIO changes for v4.17
From: Linus Walleij
Date: Wed Apr 04 2018 - 07:19:39 EST
Hi Linus,
here is the major slew of GPIO changes for v4.17.
Some things to notice:
- I merged in v4.16-rc5 to get rid of a really nasty merge
conflict that was making it hard to rebuild linux-next, and
this happened due to a big fix in the Renesas R-Car driver
collding with ongoing development.
- There is a series of ISA_BUS_API changes that ended up
getting queued in my tree. Most of them have proper ACKs
and they have been tested throughly in linux-next.
These patches finally split ISA_BUS and ISA_BUS_API
apart as I understand it, as there are devices using
port-mapped I/O but not strictly speaking using any ISA
bus. So the ISA_BUS and the ISA_BUS_API are two
things. The most notable effect of ISA_BUS_API is that
it compiles drivers/base/isa.c so that we get device driver
core infrastructure for these devices. The ISA bus was merged
in 2006 (a5117ba7da37) and was used for sound cards and
watchdog, but only recently William started
to use it for his industrial data acquisition cards and he's found
a bit of problems that are now (hopefully) finally fixed up.
Any questions: William Breathitt Gray is on the CC for this
pull request to answer them.
Any other details are in the signed tag.
Please pull it in!
Yours,
Linus Walleij

gpio: Add Spreadtrum PMIC EIC driver support (2018-03-27 15:51:22 +0200)
----------------------------------------------------------------
This is the bulk of GPIO changes for the v4.17 kernel cycle:
New drivers:
- Nintendo Wii GameCube GPIO, known as "Hollywood"
- Raspberry Pi mailbox service GPIO expander
- Spreadtrum main SC9860 SoC and IEC GPIO controllers.
Improvements:
- Implemented .get_multiple() callback for most of the
high-performance industrial GPIO cards for the ISA bus.
- ISA GPIO drivers now select the ISA_BUS_API instead of
depending on it. This is merged with the same pattern
for all the ISA drivers and some other Kconfig cleanups
related to this.
Cleanup:
- Delete the TZ1090 GPIO drivers following the deletion of
this SoC from the ARM tree.
- Move the documentation over to driver-api to conform with
the rest of the kernel documentation build.
- Continue to make the GPIO drivers include only
<linux/gpio/driver.h> and not the too broad <linux/gpio.h>
that we want to get rid of.
- Managed to remove VLA allocation from two drivers pending
more fixes in this area for the next merge window.
- Misc janitorial fixes.
