Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next
This time mostly cleanups around the runtime power management handling
and slightly improved GPU hang handling. Also some additions to the
HWDB to get the driver working properly on more NXP i.MX8MP IP cores.

drm/mediatek: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert the mediatek drm drivers from always returning zero in
the remove callback to the void returning variant.

drm/i915/guc: Fix potential null pointer deref in GuC 'steal id' test
It was noticed that if the very first 'stealing' request failed to
create for some reason then the 'steal all ids' loop would immediately
exit with 'last' still being NULL. The test would attempt to continue
but using a null pointer. Fix that by aborting the test if it fails to
create any requests at all.

WA_22016122933 was recently applied to all MeteorLake engines, which is
simultaneously too broad (should only apply to Media engines) and too
specific (should apply to all platforms that use the same media engine
as MeteorLake). Correct this in cases where coherency settings are
modified.
There were also two additional places where the workaround was applied
unconditionally. The change was confirmed as necessary for all
platforms, so the workaround label was removed.

drm/i915: fix display probe for IVB Q and IVB D GT2 server
The current display probe is unable to differentiate between IVB Q and
IVB D GT2 server, as they both have the same device id, but different
subvendor and subdevice. This leads to the latter being misidentified as
the former, and should just end up not having a display. However, the no
display case returns a NULL as the display device info, and promptly
oopses.
As the IVB Q case is rare, and we're anyway moving towards GMD ID,
handle the identification requiring subvendor and subdevice as a special
case first, instead of unnecessarily growing the intel_display_ids[]
array with subvendor and subdevice.

drm/mediatek: dp: Don't register HPD interrupt handler for eDP case
The interrupt handler for HPD is useful only if a display is actually
supposed to be hotpluggable, as that manages the machinery to perform
cable (un)plug detection, debouncing and setup for re-training.
Since eDP panels are not supposed to be hotpluggable we can avoid
using the HPD interrupts altogether and rely on HPD polling only
for the suspend/resume case, saving us some spinlocking action and
the overhead of interrupts firing at every suspend/resume cycle,
achieving a faster (even if just slightly) display resume.

drm/mediatek: dp: Add .wait_hpd_asserted() for AUX bus
In order to support usecases in which the panel regulator can be
switched on and off to save power, and usecases in which the panel
regulator is off at boot, add a .wait_hpd_asserted() callback for
the AUX bus: this will make sure to wait until the panel is fully
ready after power-on before trying to communicate with it.
Also, parse the eDP display capabilities in that callback, so that
we can also avoid using the .get_edid() callback from this bridge.
Since at this point the hpd machinery is performed in the new hpd
callback and the detection and edid reading are done outside of
this driver, assign the DRM_BRIDGE_OP_{DETECT, EDID, HPD} ops and
register the bridge unconditionally at probe time only if we are
probing full DisplayPort and not eDP while, for the latter, we
register the bridge in the .done_probing() callback and only if
the panel was found and triggered HPD.

drm/mediatek: dp: Add support for embedded DisplayPort aux-bus
For the eDP case we can support using aux-bus on MediaTek DP: this
gives us the possibility to declare our panel as generic "panel-edp"
which will automatically configure the timings and available modes
via the EDID that we read from it.
To do this, move the panel parsing at the end of the probe function
so that the hardware is initialized beforehand and also initialize
the DPTX AUX block and power both on as, when we populate the
aux-bus, the panel driver will trigger an EDID read to perform
panel detection.
Last but not least, since now the AUX transfers can happen in the
separated aux-bus, it was necessary to add an exclusion for the
cable_plugged_in check in `mtk_dp_aux_transfer()` and the easiest
way to do this is to simply ignore checking that when the bridge
type is eDP.

It is useless and error-prone to enable the DisplayPort event interrupt
before finishing to probe and install the driver, as the DP training
cannot happen before the entire pipeline is correctly set up, as the
interrupt handler also requires the full hardware to be initialized by
mtk_dp_bridge_attach().
Anyway, depending in which state the controller is left from the
bootloader, this may cause an interrupt storm and consequently hang
the kernel during boot, so, avoid enabling the interrupt until we
reach a clean state by adding the IRQ_NOAUTOEN flag before requesting
it at probe time and manage the enablement of the ISR in the .attach()
and .detach() handlers for the DP bridge.
