Here is the list of fixes that I have for drm/mali-dp. They've been on the mailing
lists for a while and merged into linux-next for a few weeks, but due to holiday and
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
cleanup of DRM_ROTATE series that is already in drm-next), but if you do that would
be great.
* 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld:
drm: mali-dp: Clear CVAL when leaving config mode
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
drm: mali-dp: Refactor plane initialisation
arm: mali-dp: Extract mode_config cleanup into malidp_fini
drm: mali-dp: Add pitch alignment check for planes
drm: mali-dp: Add pitch alignment check function
drm: mali-dp: Set the drm->irq_enabled flag to match driver's state.
drm: mali-dp: Clear the config_valid flag before using it in wait_event.
We need to explicitly disable our planes, so don't set the flag which
would otherwise skip the plane disable when the CRTC is disabled.

Split out malidp_fini as the opposite of malidp_init. This helps keep
the cleanup paths neat and easier to manage.

Mali DP driver does not use drm_irq_{un,}install() function so the
drm->irq_enabled flag does not get set automatically.
drm_wait_vblank() checks the value of the flag among other functions.

config_valid variable is used to signal the activation of the CVAL
request when the vsync interrupt has fired. malidp_set_and_wait_config_valid()
uses the variable in wait_event_interruptible_timeout without clearing it
first, so the wait is skipped.

Connectors shouldn't be registered until the rest of the whole device
is set up, so that consistent state is presented to userspace.
As such, remove the calls to drm_connector_register() and
drm_connector_unregister() from tda998x, as these are now handled by
drm_dev_(un)register() itself.
To work with this change, the mali-dp and hdlcd bind and unbind
sequences have to be reordered, to ensure that the componentised
encoder/connector is bound before drm_dev_register() registers all
connectors. Similarly, the device must be unregistered before the
component is unbound.
Altogether, this allows other drivers using tda998x to be
de-midlayered, and to have less racy initialisation of their components.
Splitting this commit into three (one per driver) isn't possible without
intermediate breakage, so it is all squashed together here.

Add support for the new family of Display Processors from ARM Ltd.
This commit adds basic support for Mali DP500, DP550 and DP650
parts, with only the display engine being supported at the moment.
