Instead of obtaining the width/height of the framebuffer from the CRTC

Wait for the object to be idle before changing its cache-level and
unbinding. This was dropped as supposedly superfluous from commit
8b1c78e06e61 ("drm/i915: Avoid calling i915_gem_object_unbind holding
object lock"), but it turns out to prevent some cache dirt escaping.
Smells like papering over a race...

The GMA500 driver is using the legacy GPIO API to fetch
three optional display control GPIO lines from the SFI
description used by the Medfield platform.
Switch this over to use GPIO descriptors and delete the
custom platform data.
We create three new static locals in the tc35876x bridge
code but it is hardly any worse than the I2C client static
local already there: I tried first to move it to the DRM
driver state container but there are workarounds for
probe order in the code so I just stayed off it, as the
result is unpredictable.
People wanting to do a more throrugh and proper cleanup
of the GMA500 driver can work on top of this, I can't
solve much more since I don't have access to the hardware,
I can only attempt to tidy up my GPIO corner.

Just like in commit 523e0cc89b83 ("drm/i915/tgl: allow DVI/HDMI on port
A"), the port checks when reading the VBT can easily not match what the
platform really exposes. However here we only have some additional debug
messages that are not adding much value: in the previous debug message
we already print everything we know about the VBT.
Instead of keep fixing the possible port assignments according to the
platform, just nuke the additional messages.

While not good behaviour, it is, however, established behaviour that we

v3: Drop the combo phy assertion. It was backward before, but doesn't
seem terribly necessary. I'm keeping the IS_ICELAKE assertion
though since we often copy/paste/modify the power well tables when
defining new platforms and it's too easy to cargo cult the

The TGL workaround database no longer shows Wa #1178 (or anything
similar under different workaround names/numbers) so we should be able
to drop it. In fact Swati just discovered that applying this workaround
is the root cause of some power well enable failures we've been seeing
in CI (gitlab issue 498).
Once we stop applying this WA, TGL no longer utilizes any of the special
handling provided by icl_combo_phy_aux_power_well_ops so we can just
drop back to using the standard hsw-style power well ops instead.

Outputs C and D on EHL are combo PHY outputs and thus should not be
using the same TC AUX power well handlers as ICL. And even though
icl_combo_phy_aux_power_well_ops works okay for EHL/JSL combo PHYs none
of its special handling is actually necessary for this platform:
* EHL/JSL don't actually need to program PORT_CL_DW12
* Display WA #1178 does not apply to EHL/JSL
Thus we can simply drop back to using our standard "hsw-style" power
well ops for EHL AUX power wells.

When CONFIG_XEN_BALLOON_MEMORY_HOTPLUG is not defined
reserve_additional_memory() will set balloon_stats.target_pages to a
wrong value in case there are still some ballooned pages allocated via
alloc_xenballooned_pages().
This will result in balloon_process() no longer be triggered when
ballooned pages are freed in batches.

Objects allocated by xen_blkif_alloc come from the 'blkif_cache' kmem
cache. This cache is destoyed when xen-blkif is unloaded so it is
necessary to wait for the deferred free routine used for such objects to
complete. This necessity was missed in commit 14855954f636 "xen-blkback:
allow module to be cleanly unloaded". This patch fixes the problem by
taking/releasing extra module references in xen_blkif_alloc/free()
respectively.

SMB2_tdis() checks if a root handle is valid in order to decide
whether it needs to close the handle or not. However if another
thread has reference for the handle, it may end up with putting
the reference twice. The extra reference that we want to put
during the tree disconnect is the reference that has a directory
lease. So, track the fact that we have a directory lease and
close the handle only in that case.

Commit 5e6669387e22 ("of/platform: Pause/resume sync state during init
and of_platform_populate()") paused/resumed sync state during init only
if Linux had parsed and populated a devicetree.
However, the check for that (of_have_populated_dt()) can change after
of_platform_default_populate_init() executes. One example of this is
when devicetree unittests are enabled. This causes an unmatched
pause/resume of sync state. To avoid this, just unconditionally
pause/resume sync state during init.

Fix device memory flows so that only once there will be no live mmaped
VA to a given allocation the matching object will be destroyed.
This prevents a potential scenario that existing VA that was mmaped by
one process might still be used post its deallocation despite that it's
owned now by other process.
The above is achieved by integrating with IB core APIs to manage
mmap/munmap. Only once the refcount will become 0 the DM object and its
underlay area will be freed.

Since 62240a88004b ("PCI: rockchip: Drop storing driver private outbound
resource data), the offset calculation is wrong to access the register
