In invalidate and flush functions of eDP DRRS, if deferred downclock
work starts execution at a time window between acquiring the drrs
mutex and cancellation of the deferred work
(intel_edp_drrs_downclock_work), then deferred work will find
drrs mutex locked and wait for the same.
Meanwhile the function that acquired mutex drrs invalidate/flush will
wait for the completion of the deferred work before releasing the mutex.
Thats a deadlock.
To avoid such deadlock scenario, this change cancels the deferred work
before acquiring the mutex at invalidate and flush functions.

The current minimum vco frequency leaves us with a gap in our supported
frequencies at 233-243 MHz. Your typical 2560x1440@60 display wants a
pixel clock of 241.5 MHz, which is just withing that gap. Reduce the
allowed vco min frequency to 4.8GHz to reduce the gap to 233-240 MHz,
and thus allow such displays to work.
4.8 GHz is actually the documented (at least in some docs) limit of the
PLL, and we just picked 4.86 GHz originally because that was the lowest
value produced by the PLL spreadsheet, which obviously didn't consider
2560x1440 displays.

This reverts commit 3f678c96ab.
We've been a bit too optimistic with this one here :(
The trouble is that internally we're still using these plane
update/disable hooks. Which was totally ok pre-atomic since the drm
core did all the book-keeping updating and these just mostly updated
hw state. But with atomic there's lots more going on, and it causes
heaps of trouble with the load detect code.
This one specifically cause a deadlock since both the load detect code
and the nested plane atomic helper functions tried to grab the same
locks. It only blows up because of the evil tricks though we play with
the implicit ww acquire context.
Applying this revert unearths the NULL deref on already freed
framebuffer objects reported as a regression in 4.0 by various people.
Fixing this will be fairly invasive, hence revert even for the
4.1-next queue.

With the two-step reset counter increments which braket the actual

out of waits with -EAGAIN (or -EIO) in that case there is not risk of
lost interrupt enabling bits when the lockless wait code races against
a gpu reset.

The cursor size fields in intel_crtc just duplicate the data from
cursor->state.crtc_{w,h} so we don't need them any more. Worse, their
use in the watermark code actually introduces a subtle bug since they
don't get updated to mirror the state values until the plane commit
stage, which is *after* we've already used them to calculate new
watermark values. This happens because we had to move watermark updates
slightly earlier (outside vblank evasion) in commit

Since the beginning, sysfs/connector/status has done a heavyweight
detection of the current connector status. But no user, such as upowerd
or logind, has ever desired to initiate a probe. Move the probing into a
new attribute so that existing readers get the behaviour they desire.
v2: David Herrmann suggested using "echo detect > /sys/.../status" to
trigger the probing, which is a fine idea. This extends that to also
allow the user to apply the force detection overrides at runtime.

drm: Don't grab an fb reference for the idr
we've switched to weak references, broke that assumption but forgot to
fix it up.
Since we still force-disable planes it's only possible to hit this
when racing multiple rmfb with fbdev restoring or similar evil things.
As long as userspace is nice it's impossible to hit the BUG_ON.
But the BUG_ON would most likely be hit from fbdev code, which usually
invovles the console_lock besides all modeset locks. So very likely
we'd never get the bug reports if this was hit in the wild, hence
better be safe than sorry and backport.

drm: atmel-hlcdc: Add pinctrl PM select sleep,default state in CRTC suspend/resume
drm: atmel-hlcdc: Add PM suspend/resume support
drm: atmel-hlcdc: add discard area support
drm: atmel-hlcdc: Atomic mode-setting conversion
A number of TDA998x updates for the next merge window. Patches
included in this set are:
* adding support for finding the attached CRTCs from DT
* a fix function name mis-spelling in a dev_err()
* simplify the EDID reading by using the drm_do_get_edid() function
instead of coding this ourselves.
* 'drm-tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
drm/i2c: tda998x: use drm_do_get_edid()
drm/i2c: tda998x: fix misspelling of current function in string
drm/i2c: tda998x: add OF support for finding attached CRTCs
Fixup some fallout of the fallout of atomic dpms, few mdp5 cursor
fixes, fix a leak in error path, and some fixes for kexec
* 'msm-fixes-4.0' of git://people.freedesktop.org/~robclark/linux:
drm/msm: kexec fixes
drm/msm/mdp5: fix cursor blending
drm/msm/mdp5: fix cursor ROI
drm/msm/atomic: Don't leak atomic commit object when commit fails
drm/msm/mdp5: Avoid flushing registers when CRTC is disabled
drm/msm: update generated headers (add 6th lm.base entry)
drm/msm/mdp5: fixup "drm/msm: fix fallout of atomic dpms changes"
In kexec environment, we are more likely to encounter irq's already
enabled from previous environment. At which point we find that writes
to disable/clear pending irq's are slightly less than useless without
first enabling clocks.
TODO: full blown state read-in so kexec'd kernel can inherit the mode
already setup.

Seems like we just want BLEND_EN and not BLEND_TRANSP_EN (setting the
latter results in black pixels in the cursor image treated as
transparent).

If cursor is set near the edge of the screen, it is not valid to use the
new cursor width/height as the ROI dimensions. Split out the ROI calc
and use it both cursor_set and cursor_move.

If the atomic commit fails due to completion wait interruption the
atomic commit object is not freed and is thus leaked. Free it.

When a CRTC is disabled, no CTL is allocated to it (CRTC->ctl == NULL);
in that case we should not try to FLUSH registers and do nothing instead.
This can happen when we try to move a cursor but the CRTC's CTL
(CONTROL) has not been allocated yet (inactive CRTC).
It can also happens when we .atomic_check()/.atomic_flush() on a
disabled CRTC.
A CTL needs to be kept as long as the CRTC is alive. Releasing it
after the last VBlank is safer than in .atomic_flush().

Some target have up to 6 layer mixers (LM).
Let the header file access the last LM's base address.

Commit 0b776d457b ("drm/msm: fix fallout of atomic dpms
changes") has a typo in both mdp5_encoder_helper_funcs and
mdp5_crtc_helper_funcs definitions:
.dpms entry should be replaced by .disable and .enable
Also fixed a typo in mdp5_encoder_enable().
Note that these typos are only present for MDP5. MDP4 is fine.
