Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Highlights
----------
Re-factoring works over the exynos drm framework.
- drm_crtc, drm_encoder/drm_connector are implemented by sub drivers
directly.
- Removing pm interfaces from each sub driver, and implementing them
at top level of exynos drm.
Add DisplayPort Transmitter driver.
- Just moving existing driver from drivers/vides/exynos into
drivers/gpu/drm/exynos.
Add new LVDS bridge driver, PTN3460.
- Placed in drivers/gpu/drm/bridge, and this device is used to transfer
image signal from DP(DisplayPort) to LVDS Panel.
So this driver will be used with DP driver moved into exynos drm.
Add parallel panel support
- With the re-factoring patch series, existing parallel panel support was
broken by moving exynos_drm_display ops into each real connector driver,
DP. So this patch series adds a new parallel panel module,
exynos_drm_dpi, for supporting parallel panel, and also adds relevant
bindings.
Some fixups and cleanups.

The locking in drm_fb_helper_initial_config is a bit troublesome for a
few reasons:
- We can't just wrap the entire function up into modeset locks since
the fbdev registration might call down into fbcon code, which then
through our ->set_par implementation needs to be able to grab all
modeset locks. So we'd have a neat deadlock.
- This implies though that all current callers don't hold any modeset
locks by necessity, so we have free reign to grab any modeset locks
we need to grab.
- The private state of the fbdev helper doesn't need any protection
through locks, since once we have the fbdev registered it is mostly
invariant or protected through the modeset locking in ->set_par and
other callbacks. We can fully rely on driver having non-racy setup
sequences here. For the initial config computation we actually may
not grab locks since drivers which provide their own magic sauce
(like i915) might need to grab locks themselves.
- We should grab locks though when we probe outputs. Currently there's
not much risk, but already now userspace could start poking at sysfs
files and so probe concurrently. I expect that in the future driver
init will be much more async, and since probing is really
time-consuming this is a prime candidate.
- We must not hold any crtc->mutex locks while calling probe functions
since those might need to lock a crtc for e.g. load detection. i915
is such a driver.
Also it's the probing calls which hit upon piles of new locking
asserts I've recently added in

drm/crtc-helper: fix locking for drm_helper_disable_unused_functions
We have two calling contexts for thise function:
- In the crtc helper code itself as part of the ->set_config
implementation. In this calling context all modeset locks are
already held, as they should.
- In drivers not implementing fastboot before the fbdev/fbcon setup
and initialization. This has been added for all drivers in
drm/fb-helper: don't disable everything in initial_config
In this calling context we do not hold any modeset locks since the
immediately following call to initialize the fbev emulation grabs
all these locks themselves.
- There are two exceptions to the above rule: shmob doesn't have fbdev
emulation support. I've manually checked the callchain up to the
driver load function and no kms locks are held.
The right fix therefore is to split this helper into an internal and
external version and add the required locking to the function exported
to drivers.
This remedies locking inconsistencies exposed by me adding locking
WARNs as part of the recent kerneldoc abi polishing done in
drm/doc: Repleace LOCKING kerneldoc sections in drm_modes.c

drm/gma500: Move asle interrupt work into a work task
Previously the backlight code was called from IRQ context which isn't
allowed. This patch moves all the asle work into a work task which takes
care of the locking bug reported by users.

drm/fb-helper: Do the 'max_conn_count' zero check
Since we cannot make sure the 'max_conn_count' will always be none
zero from the users, and then if max_conn_count equals to zero, the
kcalloc() will return ZERO_SIZE_PTR, which equals to ((void *)16).
So this patch fix this with just doing the 'max_conn_count' zero check
in the front of drm_fb_helper_init().

drm/fb-helper: Use drm_fb_helper_restore_fbdev_mode() in drm_fb_helper_set_par()
Use drm_fb_helper_restore_fbdev_mode() in drm_fb_helper_set_par() to
make sure extra planes get disabled whenever fbcon takes over.
Otherwise the code in drm_fb_helper_set_par() was already doing the
exact same thing as drm_fb_helper_restore_fbdev_mode(), so this doesn't
change the behaviour in any other way.

Merge branch 'drm-minor' of git://people.freedesktop.org/~dvdhrm/linux into drm-next
This series contains several cleanups for the DRM-minor handling. All but the
last one reviewed by Daniel and tested by Thierry. Initially, the series
included patches to convert minor-handling to a common base-ID, but have
been NACKed by Daniel so I dropped them and only included the main part in the
last patch. With this in place, drm_global_mutex is no longer needed for
minor-handling (but still for device unregistration..).
There are some pending patches that try to remove the global mutex entirely, but
they need some more reviews and thus are not included.
* 'drm-minor' of git://people.freedesktop.org/~dvdhrm/linux:
drm: make minors independent of global lock
drm: inline drm_minor_get_id()
drm: coding-style fixes in minor handling
drm: remove redundant minor->device field
drm: remove unneeded #ifdef CONFIG_DEBUGFS
drm: rename drm_unplug/get_minor() to drm_minor_register/unregister()
