2dc8f81e4f drm/amdgpu: SR-IOV data exchange between PF&VF
SR-IOV need to exchange some data between PF&VF through shared VRAM

PF will copy some necessary firmware and information to the shared
VRAM. It also requires some information from VF. PF will send a
key through mailbox2 to help guest calculate checksum so that it can
verify whether the data is correct.

So check the data on the specified offset of the shared VRAM, if the
checksum is right, read values from it and write some VF information
next to the data from PF.

bfddd14697 drm/sun4i: hdmi: Move PAD_CTRL1 setting to mode_set function
Initially we configured the PAD_CTRL1 register at probe/bind time.
However it seems the HDMI controller will modify some of the bits
in this register by itself. On the A10 it is particularly annoying
as it toggles the output invert bits, which inverts the colors on
the display output.

The U-boot driver this driver is based on sets this register twice,
though it seems it's only needed for actual display output. Hence
we move it to the mode_set function.

While debugging inverted color from the HDMI output on the A10, I
found that the lowest 3 bits were set. These were cleared on A20
boards that had normal display output. By manually toggling these
bits the mapping of the color components to these bits was found.

While these are not used anywhere, it would be nice to document
them somewhere.

936598d16e drm/sun4i: backend: Add comment explaining why registers are cleared
Many of the backend's layer configuration registers have undefined
default values. This poses a risk as we use regmap_update_bits in
some places, and don't overwrite the whole register.

At probe/bind time we explicitly clear all the control registers
by writing 0 to them. This patch adds a more detailed explanation
on why we're doing this.

e8afb7b67f drm/sun4i: don't add components that are already in the queue
Even though the components framework can handle duplicate entries,
the extra entries cause a lot more debug messages to be generated,
which would be confusing to developers not familiar with our driver
and the framework in general.

Instead, we can scan the relatively small queue and check if the
component to be added is already queued up. Since the display
pipelines are symmetrical (not considering the third display
pipeline on the A80), and we add components level by level, when
we get to the second instance at the same level, any shared downstream
components would already be in the queue.

The documentation said to use src_w here, and I didn't consider that
we actually needed to be using pitch somewhere in our setup.  Fixes
scanout on my DSI panel when X11 does initial setup with 1920x1080
HDMI and 800x480 DSI both at 0,0 of the same framebuffer.

v2: Add some comments requested by Boris

787e1b74b7 Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next
Most notable addition this time is the support for the GPU performance
counters by Christian. This has been in the making for some time and it
has matured a lot. Since this is adding UAPI, the corresponding WIP
userspace can be found at [1] mesa/libdrm repos. I expect that
Christian sends out the final userspace patches for this once you have
pulled the kernel bits.

Philipp optimized the probe path, so etnaviv gets out of the way for
systems that want to boot real quick.

I've done mostly cleanups, disentangling etnaviv from the IOMMU API,
with some MMUv1 optimizations on the way.

* 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux: (36 commits)
  drm/etnaviv: remove unnecessary clock stabilization delay
  drm/etnaviv: reduce reset delay

d409eeafa9 drm/vc4: Move the DSI clock divider workaround closer to the clock call.
We want the adjusted_mode->clock to be the actual clock we're
expecting to program, so that consumers see the right values for clock
and vrefresh.

512721a14a drm/drm_of: Move drm_of_panel_bridge_remove_function into header.
Core drm shouldn't depend on anything in drm-kms-helper, or the drm
module will fail to load.

insmod drm fails with
[ 6087.674390] drm: Unknown symbol drm_panel_bridge_remove (err 0)

which is defined in drm_kms_helper.ko

This call was added by commit c70087e8f1 ("drm/drm_of: add
drm_of_panel_bridge_remove function"), and the fix is defining it in the
drm_of.h header, to break the circular dependency.
