IRQs are properly shut down, so it almost works as race-free shutdown.
Except the irq is stopped after the vblank stuff, so boom anyway.
Proper way would be to call drm_atomic_helper_shutdown before any of
the kms things gets stopped. So no harm in removing the
drm_vblank_cleanup here really.
Same story for both hdlcd and mali.

Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.
Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.
As a result these defines are provided purely as a convenience to
userspace applications.
Changes since v3:
- Switched away from past tense in comments
- Add define name change to previously mis-spelled DRM_REFLECT_X comment
- Improved the comment for the DRM_MODE_REFLECT_<axis> comment
Changes since v2:
- Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
- Fix compilation errors
- Changed comment formatting
- Deduplicated comment lines
- Clarified DRM_MODE_PROP_REFLECT_ comment
Changes since v1:
- Moved defines from drm.h to drm_mode.h
- Changed define prefix from DRM_ to DRM_MODE_PROP_
- Updated uses of the defines to the new prefix
- Removed include from drm_rect.c
- Stopped using the BIT() macro

When downscaling, mclk needs to be sufficiently higher than pxlclk in
order to be able to fetch the higher-resolution data and produce output

Convert drivers to use the new of_graph_get_remote_node() helper
instead of parsing the endpoint node and then getting the remote device
node. Now drivers can just specify the device node and which
port/endpoint and get back the connected remote device node. The details
of the graph binding are nicely abstracted into the core OF graph code.
This changes some error messages to debug messages (in the graph core).
Graph connections are often "no connects" depending on the particular
board, so we want to avoid spurious messages. Plus the kernel is not a
DT validator.

The rate of mclk depends on the use-case. If no downscaling is required,
then mclk == pxlclk is a valid option; with downscaling however, the
rate at which mclk runs determines how much a plane can be downscaled
before composition. This is a system integration + power management
issue that is more suited to firmware rather than this driver.

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

Backmerge tag 'v4.9-rc8' into drm-next
Linux 4.9-rc8
Daniel requested this so we could apply some follow on fixes cleanly to -next.
While testing HDMI with Xorg on the Juno board, I find that when Xorg
starts up or shuts down, the display is shifted significantly to the
right and wrapped in the active region. (No sync bars are visible.)
The timings are correct, it behaves as if the start address has been
shifted many pixels _into_ the framebuffer.
This occurs whenever the display mode size is changed - using xrandr
in Xorg shows that changing the resolution triggers the problem
almost every time, but changing the refresh rate does not.
Using devmem2 to disable and re-enable the HDLCD resolves the issue,
and repeated disable/enable cycles do not make the issue re-appear.
Further debugging shows that we try to update the controller
configuration while enabled.
Alwys ensure that the HDLCD is disabled prior to updating the
controller timings, and use drm_crtc_vblank_off()/drm_crtc_vblank_on()
so that DRM knows whether it can expect vblank interrupts.

travel to Linux Plumbers I did not send the pull request earlier. I don't know if
these patches can be pulled into v4.9 still (they will conflict with Ville Syrjälä's

be great.

drm/arm: mark symbols static where possible
drm: mali-dp: Add support for setting plane's rotation property from userspace.
drm: mali-dp: Don't set DRM_PLANE_COMMIT_ACTIVE_ONLY
drm: mali-dp: Store internal format and n_planes in plane state
drm: mali-dp: Enable alpha blending

It's possible for CVAL to get set whilst we are in config mode. If this
happens, afer we leave config mode the HW will latch whatever
configuration is in the registers at the next vsync. Most likely this
will be a partial configuration, as we'll be racing against the ongoing
atomic_commit.
