github.com:bbrezillon/linux-at91 into drm-fixes
Two trivial bugfixes for the atmel-hlcdc driver.
The first one is making use of __drm_atomic_helper_crtc_destroy_state()
instead of duplicating its logic in atmel_hlcdc_crtc_reset() and
risking memory leaks if other objects are added to the common CRTC
state.
The second one is fixing a possible NULL pointer dereference.

"I have accumulated some cleanup patches for HDLCD, partly triggered by
Daniel Vetter's work on non-blocking atomic operations, that I would like
to integrate into v4.7. My first patch is important for the newly enabled
hibernate option for AArch64 on Juno, the others are fixing behaviour in
HDLCD and adding a debugfs entry to help track the underlying framebuffer
usage. I'm also taking one of Daniel's patches from his non-blocking series
to help with the integration of his patches later."

drm_fb_cma code has a nice helper function to display in the debugfs
information about the underlying framebuffers used by HDLCD:
$ cat /sys/kernel/debug/dri/0/fb
fb: 1920x1200@XR24
0: offset=0 pitch=7680, obj: 0 ( 2) 001011ba 0x00000000fc300000 ffffff800a27c000 9338880

Add the entry in HDLCD's debugfs node.

Harden the plane_check() code to drop attempts at scaling because
that is not supported. Make hdlcd_plane_atomic_update() set the pitch
and line length registers that correctly reflect the plane's values.
And make hdlcd_crtc_mode_set_nofb() a helper function for
hdlcd_crtc_enable() rather than an exposed hook.

event_list just reimplemented what drm_crtc_arm_vblank_event does. And
we also need to send out drm events when shutting down a pipe.
With this it's possible to use the new nonblocking commit support in
the helpers.

Because the HDLCD driver acts as a component master it can end
up enabling the runtime PM functionality before the encoders
are initialised. This can cause crashes if the component slave
never probes (missing module) or if the PM operations kick in
before the probe finishes.
Move the enabling of the runtime PM after the component master
has finished collecting the slave components and use the DRM
atomic helpers to suspend and resume the device.

more lockless gem BO patches acked/reviewed by driver maintainers.

afee4d8707ab1f21b7668de995be3a5961e83582 Revert "drm/i915: Avoid stalling on pending flips for legacy cursor updates"
"drm/i915: Allow nonblocking update of pageflips" should have been
split up, misses a proper commit message and seems to cause issues in
the legacy page_flip path as demonstrated by kms_flip.
"drm/i915: Make unpin async" doesn't handle the unthrottled cursor
updates correctly, leading to an apparent pin count leak. This is
caught by the WARN_ON in i915_gem_object_do_pin which screams if we
have more than DRM_I915_GEM_OBJECT_MAX_PIN_COUNT pins.
Unfortuantely we can't just revert these two because this patch series
came with a built-in bisect breakage in the form of temporarily
removing the unthrottled cursor update hack for legacy cursor ioctl.
Therefore there's no other option than to revert the entire pile :(
There's one tiny conflict in intel_drv.h due to other patches, nothing
serious.
Normally I'd wait a bit longer with doing a maintainer revert, but
since the minimal set of patches we need to revert (due to the bisect
breakage) is so big, time is running out fast. And very soon
(especially after a few attempts at fixing issues) it'll be really
hard to revert things cleanly.
Lessons learned:
- Not a good idea to rush the review (done by someone fairly new to
the area) and not make sure domain experts had a chance to read it.
- Patches should be properly split up. I only looked at the two
patches that should be reverted in detail, but both look like the
mix up different things in one patch.
- Patches really should have proper commit messages. Especially when
doing more than one thing, and especially when touching critical and
tricky core code.
- Building a patch series and r-b stamping it when it has a built-in
bisect breakage is not a good idea.
- I also think we need to stop building up technical debt by
postponing atomic igt testcases even longer. I think it's clear that
there's enough corner cases in this beast that we really need to
have the testcases _before_ the next step lands.

Since the introduction of (struct_mutex) lockless GEM bo freeing, there
are a pair of driver vfuncs for freeing the GEM bo, of which the driver
may choose to only implement driver->gem_object_free_unlocked (and so
avoid taking the struct_mutex along the free path). However, the CMA GEM
helpers were still calling driver->gem_free_object directly, now NULL,
and promptly dying on the fancy new lockless drivers. Oops.
Robert Foss bisected this to b82caafcf2303 (drm/vc4: Use lockless gem BO
free callback) on his vc4 device, but that just serves as an enabler for
9f0ba539d13ae (drm/gem: support BO freeing without dev->struct_mutex).

After commit 027b3f8ba9277410c3191d72d1ed2c6146d8a668 ("drm/modes: stop
handling framebuffer special") extra fb refs are left around when doing
atomic modesetting.
The problem is that the new drm_property_change_valid_get() does not
return anything in the '**ref' parameter, which causes
drm_property_change_valid_put() to do nothing.
For some reason this doesn't cause problems with legacy API.
Also, previously the code only set the 'ref' variable for fbs, with this
patch the 'ref' is set for all objects.

drm_atomic_set_mode_prop_for_crtc() does not clear the state->mode, so
old data may be left there when a new mode is set, possibly causing odd
issues.
This patch improves the situation by always clearing the state->mode
first.

Commit 652353e6e561c2aeeac62df183f721f6f9b5b45f ("drm/sti: set CRTC
modesetting parameters") added a hack to avoid warnings related to
setting mode with atomic API. With the previous patch, the hack should
no longer be necessary.

When setting mode via MODE_ID property,
drm_atomic_set_mode_prop_for_crtc() does not call
drm_mode_set_crtcinfo() which possibly causes:
"[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 32: Can't
calculate constants, dotclock = 0!"
Whether the error is seen depends on the previous data in state->mode,
as state->mode is not cleared when setting new mode.
This patch adds drm_mode_set_crtcinfo() call to
drm_mode_convert_umode(), which is called in both legacy and atomic
paths. This should be fine as there's no reason to call
drm_mode_convert_umode() without also setting the crtc related fields.
drm_mode_set_crtcinfo() is removed from the legacy drm_mode_setcrtc() as
that is no longer needed.

Since my last struct_mutex crusade someone escaped!
This already has the advantage that for the common case when someone
else holds a ref the unref won't even acquire dev->struct_mutex. And
I'm working on code to allow drivers to completely opt-out of any and
all dev->struct_mutex usage, but that only works if they use the
_unlocked variants everywhere.

Code stolen from gma500.
This is just a minor bit of safety code that I spotted and figured it
might be useful if we put it into the core. This is to make the
get_gamma ioctl reflect likely reality even before the first set_gamma
ioctl call.
