Two fixups
- It fixes wrong return value by returing proper error value instead of
fixed one.
- It fixes ref count leak in mic_pre_enable.
One cleanup
- It removes dev_err() call on platform_get_irq() failure because
platform_get_irq() call dev_err() itself on failure.

[Why]
Changes that are fast don't require updating DLG parameters making
this call unnecessary. Considering this is an expensive call it should
not be done on every flip.
DML touches clocks, p-state support, DLG params and a few other DC
internal flags and these aren't expected during fast. A hang has been
reported with this change when called on every flip which suggests that
modifying these fields is not recommended behavior on fast updates.
[How]
Guard the validation to only happen if update type isn't FAST.

Rearrange the allocation of the mm_struct registration to avoid
allocating underneath the i915->mm_lock, so that we avoid tainting the
lock (and in turn many other locks that may be held as i915->mm_lock is
taken, and those locks we may want on the free [shrinker] paths). In
doing so, we convert the lookup to be RCU protected by courtesy of
converting the free-worker to be an rcu_work.
v2: Remember to use hash_rcu variants to protect the list iteration from
concurrent add/del.

The default fbc1 compression interval we use is 500 frames. That
translates to over 8 seconds typically. That's rather excessive
so let's drop it to 1 second.
The hardware will not attempt recompression unless at least one
line has been modified, so a shorter compression interval should
not cause extra bandwidth use in the purely idle scenario. Of
course in the mostly idle case we are possibly going to recompress
a bit more.
Should really try to find some kind of sweet spot to minimize
the energy usage...

The current fence_y_offset calculation is broken. I think it more or
less used to do the right thing, but then I changed the plane code
to put the final x/y source offsets back into the src rectangle so
now it's just subtraacting the same value from itself. The code would
never have worked if we allowed the framebuffer to have a non-zero
offset.
Let's do this in a better way by just calculating the fence_y_offset
from the final plane surface offset. Note that we don't align the
plane surface address to fence rows so with horizontal panning there's
often a horizontal offset from the fence start to the surface address
as well. We have no way to tell the hardware about that so we just
ignore it. Based on some quick tests the invlidation still happens
correctly. I presume due to the invalidation nuking at least the full
line (or a segment of multiple lines).

As we close a handle GEM object, we update the drm_file's idr with an
error^W NULL pointer to indicate the in-progress closure, and finally
removing it. If we read the idr directly, we may then see an invalid
object pointer, and in our debugfs per_file_stats() we therefore need
to protect against the entry being invalid.

The HPD sense mechanism in Allwinner's old HDMI encoder hardware is more
or less an input-only GPIO. Other GPIO-based HPD implementations
directly return the current state, instead of polling for a specific
state and returning the other if that times out.
Remove the I/O polling from sun4i_hdmi_connector_detect() and directly
return a known state based on the current reading. This also gets rid
of excessive CPU usage by kworker as reported on Stack Exchange [1] and
Armbian forums [2].

A single Ri mismatch doesn't automatically mean that the link integrity
is broken. Update and check of Ri and Ri' are done asynchronously. In
case an update happens just between the read of Ri' and the check against
Ri there will be a mismatch even if the link integrity is fine otherwise.

The PL111 DRM driver is now the sole user of the external
CLCD registers header file, so let's absorb that into the
pl111_drm.h file and save the external include.

This moves over some of the credit for the development of this
driver from the old fbdev driver that I used as reference when
getting this in place.

The linetime watermark is a 9 bit value, which gives us
a maximum linetime of just below 64 usec. If the linetime
exceeds that value we currently just discard the high bits
and program the rest into the register, which angers the
state checker.
To avoid that let's just clamp the value to the max. I believe
it should be perfectly fine to program a smaller linetime wm
than strictly required, just means the hardware may fetch data
sooner than strictly needed. We are further reassured by the
fact that with DRRS the spec tells us to program the smaller
of the two linetimes corresponding to the two refresh rates.

We only need the page array when the BO is about to be accessed.
So not only populate, but also create it on demand.
v2: move NULL check into ttm_tt_create()
v3: fix the occurrence in ttm_bo_kmap_ttm as well
