Subject: [GIT PULL] GPIO bulk changes for the v4.9 cycle
Hi Linus,
here are the GPIO changes for v4.9. Most of the details are
in the signed tag but note the following about merge mechanics:
- I created an immutable branch from this tree to the pin control tree
to get the new mechanism for disabling mapping of BIOS-grabbed
IRQ lines over to that tree. So it has already come in through the
pin control tree, and the SHA1 checksums should be the same
and resolve nicely in the merge.
- Lee sent me two immutable branches from the MFD tree for these
types of drivers that add a MFD nexus and some GPIO driver.
He puts a lot of effort into doing this to make things smooth in
the merge window, the only sideffect is that you will see the MFD
(and related) commits in this shortlog as well.
- I sent an immutable branch the other way around to MFD to get
the HTC EGPIO driver littering that subsystem over here to GPIO.
- I fixed a header inclusion in arch/arm/mach-omap2/* as Paul G
was removing the <linux/module.h> include from the GPIO top
include file. However the file was deleted from the OMAP tree so
there will be a trivial conflict (delete it) there.
- I have quite a few patches in the pca953x driver, and at the same
time some lockdep issue was being fixed in the i2c subsystem
affecting this driver, so Wolfram had to patch it from their end.
It should be another trivial conflict that was solved in -next.
Please pull it in!
Yours,
Linus Walleij

gpio: add missing static inline (2016-10-03 23:38:11 +0200)
----------------------------------------------------------------
This is the bulk of GPIO changes for the v4.9 series:
Subsystem improvements:
- Do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to
me). We can now select GPIOLIB and be done with it, for all
archs. After some struggle it even work on UM. Not that it has
GPIO, but if it wants to, it can select the library.
- Continued efforts to make drivers properly either tristate or
bool.
- Introduce a warning for drivers assigning default triggers to
their irqchip lines when probed from device tree, so we find and
fix these ambigous drivers. It is agreed that in the OF config
path, the device tree defines trigger characteristics.
- The same warning, mutatis mutandis, for ACPI-probed GPIO
irqchips.
- We introduce the ability to mark certain IRQ lines as "unusable"
as they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is
put to good use in the STMPE driver and also in the Cherryview
pin control driver.
- A new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM
with allyesconfig or allmodconfig it exploded in their face.
- Move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so
now eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- New driver for the Aspeed GPIO front-end companion to the
pin controller merged through the pin control tree.
- New driver for the LP873x PMIC GPIO portions.
- New driver for Technologic Systems' I2C FPGA GPIO such as
TS4900, TS-7970, TS-7990 and TS-4100.
- New driver for the Broadcom BCM63xx series including BCM6338
and BCM6345.
- New driver for the Intel WhiskeyCove PMIC GPIO.
- New driver for the Allwinner AXP209 PMIC GPIO portions.
- New driver for Diamond Systems 48 line GPIO-MM, another of
these port-mapped I/O expansion cards.
- Support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- The STMPE driver now supports rising/falling edge detection
properly for IRQs.
- The PCA954x will now fetch and enable its VCC regulator properly.
- Major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- Switch the IOP driver to use the generic MMIO GPIO library.
- Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns.
