Pull staging and IIO updates from Greg KH:
"Here is the big staging and IIO driver pull request for 4.9-rc1.
There are a lot of patches in here, the majority due to the
drivers/staging/greybus/ subsystem being merged in with full
development history that went back a few years, in order to preserve
the work that those developers did over time.
Lots and lots of tiny cleanups happened in the tree as well, due to
the Outreachy application process and lots of other developers showing
up for the first time to clean code up. Along with those changes, we
deleted a wireless driver, and added a raspberrypi driver (currently
marked broken), and lots of new iio drivers.
Overall the tree still shrunk with more lines removed than added,
about 10 thousand lines removed in total. Full details are in the very
long shortlog below.
All of this has been in the linux-next tree with no issues. There will
be some merge problems with other subsystem trees, but those are all
minor problems and shouldn't be hard to work out when they happen
(MAINTAINERS and some lustre build problems with the IB tree)"
And furter from me asking for clarification about greybus:
"Right now there is a phone from Motorola shipping with this code (a
slightly older version, but the same tree), so even though Ara is not
alive in the same form, the functionality is happening. We are working
with the developers of that phone to merge the newer stuff in with
their fork so they can use the upstream version in future versions of
their phone product line.
Toshiba has at least one chip shipping in their catalog that
needs/uses this protocol over a Unipro link, and rumor has it that
there might be more in the future.
There are also other users of the greybus protocols, there is a talk
next week at ELC that shows how it is being used across a network
connection to control a device, and previous ELC talks have showed the
protocol stack being used over USB to drive embedded Linux boards.
I've also talked to some people who are starting to work to add a host
controller driver to control arduinos as the greybus PHY protocols are
very useful to control a serial/i2c/spio/whatever device across a
random physical link, as it is a way to have a self-describing device
be attached to a host without needing manual configuration.
So yes, people are using it, and there is still the chance that it
will show up in a phone/laptop/tablet/whatever from Google in the
future as well, the tech isn't dead, even if the original large phone
project happens to be"

Pull GPIO updates from Linus Walleij:
"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"

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.9 cycle.
General improvements:
- nicer debugfs output with one pin/config pair per line.
- continued efforts to strictify module vs bool.
- constification and similar from Coccinelle engineers.
- return error from pinctrl_bind_pins()
- pulling in the ability to selectively disable mapping of unusable
IRQs from the GPIO subsystem.

- new driver for the Aspeed pin controller family: AST2400 (G4) and
AST2500 (G5) are supported. These are used by OpenBMC on the IBM
Witherspoon platform.
- new subdriver for the Allwinner sunxi GR8.
Driver improvements:

dma_buf may live a long time, longer than the last direct user of the
driver. We already hold a reference to the owner module (that prevents
the object code from disappearing), but there is no reference to the
drm_dev - so the pointers to the driver backend themselves may vanish.
v2: Resist temptation to fix the bug in armada_gem.c not setting the
correct flags on the exported dma-buf (it should pass the flags through
and not be arbitrarily setting O_RDWR).
Use a common wrapper for exporting the dmabuf and acquiring the
reference to the drm_device.

dma_buf_export() adds a reference to the owning module to the dmabuf (to
prevent the driver from being unloaded whilst a third party still refers
to the dmabuf). However, drm_gem_prime_export() was passing its own
THIS_MODULE (i.e. drm.ko) rather than the driver. Extract the right
owner from the device->fops instead.
v2: Use C99 initializers to zero out unset elements of
dma_buf_export_info
v3: Extract the right module from dev->fops.

resources allocated with 'ida_simple_get()'.
This as been spotted with the following coccinelle script which tries to
detect missing 'ida_simple_remove()' call in error handling paths.

Pull clk framework updates from Stephen Boyd:
"The core clk framework changes are small again. They're mostly minor
fixes that weren't causing enough problems (or any problems when we're
just clarifying things) to warrant sending outside the merge window.
The majority of changes are in drivers for various SoCs. Full details
are in the logs, but here's the summary.
Core:
- Better support for DeviceTree overlays with the addition of the
CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver for a
device node that matched during of_clk_init(), unless the driver
uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE. This allows
overlays to work cleanly for drivers that must probe before the
device model is ready, and also after it's ready when an overlay is
loaded.
- Clarification in the code around how clk_hw pointers are returned
from of clk providers
- Proper migration of prepare/enable counts to parents when the clk
tree is constructed
New Drivers:
- Socionext's UniPhier SoCs
- Loongson1C
- ZTE ZX296718
- Qualcomm MDM9615
- Amlogic GXBB AO clocks and resets
- Broadcom BCM53573 ILP
- Maxim MAX77620

- Four Allwinner SoCs are migrated to the new style clk driver (A31,
A31s, A23 and A33)
- Exynos 5xxx audio and DRAM clks
- Loongson1B AC97, DMA and NAND clks
- Rockchip DDR clks and rk3399 driver tweaks
- Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer

If the expected number of FTS aren't received by RC when exiting from L0s,
the LTSSM will fall into recover state, which means it will need to send TS
for retraining which makes the latency of exiting from L0s a little longer
than expected. This issue is caused by an incorrect reset value of FTS
count on PLC1 register (offset 0x4). The expected value for Gen1/2 should
be more than 240 and we may leave a little margin here. Fix this before
starting Gen1 training which will make TS1 contain the correct FTS count.

Per TRM, we need to deassert the four reset pins simultaneously. Currently
the reset framework doesn't support that so we did it one by one. It seems
no side effect found but it does impact the state machine of controller, so
sometimes the change speed bit is not set when sending training sequence
from recover state. After the silicon RTL review from SoC guys, we don't
need to do the sequence recommended by TRM, and could just move the
deassert of mgmt_sticky_rst to the first place.

Increase the likelihood of link state to automatically go to L1 and save
some power.
The default credit update interval of 7.5 us results in the rootport
sending UpdateFC-P and UpdateFC-NP packets too often, thus resulting in the
link never going to L1, and always staying in L0/L0s. The value 24 us was
chosen after some experiments and peeking over the PCIe bus to see that we
do enter L1 substate when there is not enough traffic on the PCIe bus.

Pre DCE4 hw doesn't have reliable pageflip completion
interrupts, so instead polling for flip completion is
used from within the vblank irq handler to complete
page flips.
This causes a race if pageflip ioctl is called close to
vblank:
1. pageflip ioctl queues execution of radeon_flip_work_func.
2. vblank irq fires, radeon_crtc_handle_vblank checks for
flip_status == FLIP_SUBMITTED finds none, no-ops.
3. radeon_flip_work_func runs inside vblank, decides to
set flip_status == FLIP_SUBMITTED and programs the
flip into hw.
4. hw executes flip immediately (because in vblank), but
as 2 already happened, the flip completion routine only
emits the flip completion event one refresh later ->
wrong vblank count/timestamp for completion and no
performance gain, as instead of delaying the flip until
next vblank, we now delay the next flip by 1 refresh
while waiting for the delayed flip completion event.
Given we often don't gain anything due to this race, but
lose precision, prevent the programmed flip from executing
in vblank on pre DCE4 asics to avoid this race.
On pre-AVIVO hw we can't program the hw for edge-triggered
flips, they always execute anywhere in vblank. Therefore delay
the actual flip programming until after vblank on pre-AVIVO.

Pre DCE4 hardware doesn't have (reliable) pageflip completion
irqs, therefore we have to use the old polling method for flip
completion handling in vblank irq.
As vblank irqs fire a bit before start of vblank (when the
linebuffer fifo read position reaches end of scanout), we
have some fudge for flip completion handling in the last
lines of active scanout. Old code assumed the threshold to
be 99% of active scanout height, a ballpark estimate which
worked ok. Since we know since a while how to calculate the
actual threshold from linebuffer size, lets make use of it
to get a more accurate threshold.
This completion path is still prone to some races in corner
cases, especially on pre-AVIVO hardware, so document them
a bit better in the code comments.

The Arizona CODECs will generally function correctly without a reset line
although it is strongly advised to have one, as such we do allow the system
to boot if the reset gpio is missing or incorrectly specified. However
we should fail probe if we get a probe deferral request, this patch adds
handling for this case.

This function is only used in a single place and no new users will be
added as all the devices other required GPIOs are already handled. As
such just merge the code back into the calling function.

The McPDM in OMAP4/5 is using the pdmclk from twl6040 as functional clock.
The twl6040-pdmclk driver provides a clock which can be used to make sure
that the pdmclk is active when the McPDM is in use.
