The Rockchip LVDS driver fails to build after commit 23c35f48f5
("pinctrl: remove include file from <linux/device.h>") because it relies
on the pinctrl/consumer.h and pinctrl/devinfo.h being pulled in by the
device.h header implicitly.
Include these headers explicitly to avoid the build failure.

Pull drm updates from Dave Airlie:
"This seems to have been a comparatively quieter merge window, I assume
due to holidays etc. The "biggest" change is AMD header cleanups, which
merge/remove a bunch of them. The AMD gpu scheduler is now being made generic
with the etnaviv driver wanting to reuse the code, hopefully other drivers
can go in the same direction.
Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff
elsewhere.
Core:
- Add .last_close and .output_poll_changed helpers to reduce driver footprints
- Fix plane clipping
- Improved debug printing support
- Add panel orientation property
- Update edid derived properties at edid setting
- Reduction in fbdev driver footprint
- Move amdgpu scheduler into core for other drivers to use.
i915:

- Coffeelake stolen memory improvements
- GPU reset robustness work
- Cannonlake horizontal plane flipping
- GVT work
amdgpu/radeon:
- RV and Vega header file cleanups (lots of lines gone!)
- TTM operation context support
- 48-bit GPUVM support for Vega/RV
- ECC support for Vega
- Resizeable BAR support
- Multi-display sync support
- Enable swapout for reserved BOs during allocation
- S3 fixes on Raven
- GPU reset cleanup and fixes
- 2+1 level GPU page table
amdkfd:
- GFX7/8 SDMA user queues support
- Hardware scheduling for multiple processes
- dGPU prep work
rcar:
- Added R8A7743/5 support
- System suspend/resume support
sun4i:
- Multi-plane support for YUV formats
- A83T and LVDS support
msm:
- Devfreq support for GPU
tegra:

imx:
- Format modifier support

to the clk rate protection support added by Jerome Brunet. This feature
will allow consumers to lock in a certain rate on the output of a clk so
that things like audio playback don't hear pops when the clk frequency
changes due to shared parent clks changing rates. Currently the clk
API doesn't guarantee the rate of a clk stays at the rate you request
after clk_set_rate() is called, so this new API will allow drivers
to express that requirement. Beyond this, the core got some debugfs
pretty printing patches and a couple minor non-critical fixes.
Looking outside of the core framework diff we have some new driver
additions and the removal of a legacy TI clk driver. Both of these hit
high in the dirstat. Also, the removal of the asm-generic/clkdev.h file
causes small one-liners in all the architecture Kbuild files. Overall, the
driver diff seems to be the normal stuff that comes all the time to
fix little problems here and there and to support new hardware.
Core:
- Clk rate protection
- Symbolic clk flags in debugfs output
- Clk registration enabled clks while doing bookkeeping updates
New Drivers:
- Spreadtrum SC9860
- HiSilicon hi3660 stub
- Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
- Amlogic Meson-AXG
- ASPEED BMC
Removed Drivers:
- TI OMAP 3xxx legacy clk (non-DT) support
- asm*/clkdev.h got removed (not really a driver)
Updates:
- Renesas FDP1-0 module clock on R-Car M3-W
- Renesas LVDS module clock on R-Car V3M
- Misc fixes to pr_err() prints
- Qualcomm MSM8916 audio fixes
- Qualcomm IPQ8074 rounded out support for more peripherals

Pull poll annotations from Al Viro:
"This introduces a __bitwise type for POLL### bitmap, and propagates
the annotations through the tree. Most of that stuff is as simple as
'make ->poll() instances return __poll_t and do the same to local
variables used to hold the future return value'.
Some of the obvious brainos found in process are fixed (e.g. POLLIN
misspelled as POLL_IN). At that point the amount of sparse warnings is
low and most of them are for genuine bugs - e.g. ->poll() instance
deciding to return -EINVAL instead of a bitmap. I hadn't touched those
in this series - it's large enough as it is.
Another problem it has caught was eventpoll() ABI mess; select.c and
eventpoll.c assumed that corresponding POLL### and EPOLL### were
equal. That's true for some, but not all of them - EPOLL### are
arch-independent, but POLL### are not.
The last commit in this series separates userland POLL### values from
the (now arch-independent) kernel-side ones, converting between them
in the few places where they are copied to/from userland. AFAICS, this
is the least disruptive fix preserving poll(2) ABI and making epoll()
work on all architectures.
As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
it will trigger only on what would've triggered EPOLLWRBAND on other
architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
at all on sparc. With this patch they should work consistently on all
architectures"

For a while we've been having issues with seemingly random interrupts
coming from nvidia cards when resuming them. Originally the fix for this
was thought to be just re-arming the MSI interrupt registers right after
re-allocating our IRQs, however it seems a lot of what we do is both
wrong and not even nessecary.
This was made apparent by what appeared to be a regression in the
mainline kernel that started introducing suspend/resume issues for
nouveau:
a0c9259dc4 (irq/matrix: Spread interrupts on allocation)
After this commit was introduced, we started getting interrupts from the
GPU before we actually re-allocated our own IRQ (see references below)
and assigned the IRQ handler. Investigating this turned out that the
problem was not with the commit, but the fact that nouveau even
free/allocates it's irqs before and after suspend/resume.
For starters: drivers in the linux kernel haven't had to handle
freeing/re-allocating their IRQs during suspend/resume cycles for quite
a while now. Nouveau seems to be one of the few drivers left that still
does this, despite the fact there's no reason we actually need to since
disabling interrupts from the device side should be enough, as the
kernel is already smart enough to know to disable host-side interrupts
for us before going into suspend. Since we were tearing down our IRQs by
hand however, that means there was a short period during resume where
interrupts could be received before we re-allocated our IRQ which would
lead to us getting an unhandled IRQ. Since we never handle said IRQ and
re-arm the interrupt registers, this would cause us to miss all of the
interrupts from the GPU and cause our init process to start timing out
on anything requiring interrupts.
So, since this whole setup/teardown every suspend/resume cycle is
useless anyway, move irq setup/teardown into the pci subdev's ctor/dtor
functions instead so they're only called at driver load and driver
unload. This should fix most of the issues with pending interrupts on
resume, along with getting suspend/resume for nouveau to work again.
As well, this probably means we can also just remove the msi rearm call
inside nvkm_pci_init(). But since our main focus here is to fix
suspend/resume before 4.15, we'll save that for a later patch.

Commit bbb163e189 ("drm/nouveau/bar: implement bar1 teardown")
introduced add a teardown helper function for BAR1. During
initialisation of the Nouveau, initially all the teardown helpers are
called once, before calling their init counterparts. For gk20a, after
the BAR1 teardown function is called, the device is hanging during the
initialisation of the FB sub-device. At this point it is unclear why
this is happening and this is still under investigation. However, this
change is preventing Tegra124 devices from booting when Nouveau is
enabled. To allow Tegra124 to boot, remove the teardown helper for
gk20a.
This is based upon a previous patch by Guillaume Tucker but limits
the workaround to only gk20a GPUs.

menu stops after the first Kconfig entry without this depends on.
Since the PANEL_ORIENTATION_QUIRKS option is also used outside of DRM,
it deliberately does not have a depends on DRM, but this causes all
items after it to show as separate items rather then under the DRM
menuconfig.
This commit moves PANEL_ORIENTATION_QUIRKS to the end of the drm Kconfig
file, grouping it with DRM_LIB_RANDOM which also does not depend on DRM,
fixing the DRM menuconfig.

The 4.15 vmwgfx driver shows a warning during boot.
It is caused by a mismatch between the result of vmw_enable_vblank()
and what the drm_atomic_helper expects.

i830_disable_pipe() gets called from the power well code, and thus
we're already holding the power domain mutex. That means we can't
call plane->get_hw_state() as it will also try to grab the
same mutex and will thus deadlock.
Replace the assert_plane() calls (which calls ->get_hw_state()) with
just raw register reads in i830_disable_pipe(). As a bonus we can
now get a warning if plane C is enabled even though we don't even
expose it as a drm plane.
v2: Do a separate WARN_ON() for each plane (Chris)
