Thomas Zimmermann requested a fixes backmerge, specifically also for
96c5f82ef0 ("drm/vc4: fix error code in vc4_create_object()")
Just a bunch of adjacent changes conflicts, even the big pile of them
in vc4.

I am seeing some crash logs which imply that we are trying to use
crashdumper hw to read back GPU state when the GPU isn't initialized.
This doesn't go well (for example, GPU could be in 32b address mode
and ignoring the upper bits of buffer that it is trying to dump state
to).
I'm not *quite* sure how we get into this state in the first place,
but lets not make a bad situation worse by triggering iova fault
crashes.
While we're at it, also add the information about whether the GPU is
initialized to the devcore dump to make this easier to see in the
logs (which makes the WARN_ON() redundant and even harmful because
it fills up the small bit of dmesg we get with the crash report).

Commit 739b4e7756 ("drm/msm/dsi: Fix an error code in
msm_dsi_modeset_init()") changed msm_dsi_modeset_init() to return an
error code in case msm_dsi_manager_validate_current_config() returns
false. However this is not an error case, but a slave DSI of the bonded
DSI link. In this case msm_dsi_modeset_init() should return 0, but just
skip connector and bridge initialization.
To reduce possible confusion, drop the
msm_dsi_manager_validate_current_config() function, and specif 'bonded
&& !master' condition directly in the msm_dsi_modeset_init().

Currently the msm_dp_*** functions implement the same sequence which would
happen when drm_bridge is used. hence get rid of this intermediate layer
and align with the drm_bridge usage to avoid customized implementation.

Since commit 8f59ee9a57 ("drm/msm/dsi: Adjust probe order"), the
DSI host gets initialized earlier, but this caused unability to probe
the entire stack of components because they all depend on interrupts
coming from the main `mdss` node (mdp5, or dpu1).
To fix this issue, move mdss device initialization (which include irq
domain setup) to msm_mdev_probe() time, as to make sure that the
interrupt controller is available before dsi and/or other components try
to initialize, finally satisfying the dependency.

In preparation for registering the mdss interrupt controller earlier,
move the allocation of msm_drm_private from component bind time to
msm_drv probe; this also allows us to use the devm variant of kzalloc.
Since it is not right to allocate the drm_device at probe time (as
it should exist only when all components are bound, and taken down
when components get cleaned up), the only way to make this happen is
to pass a pointer to msm_drm_private as driver data (like done in
many other DRM drivers), instead of one to drm_device like it's
currently done in this driver.
This is also simplifying some bind/unbind functions around drm/msm,
as some of them are using drm_device just to grab a pointer to the
msm_drm_private structure, which we now retrieve in one call.

Re-work the boost and idle clamping to use PM QoS requests instead, so
they get aggreggated with other requests (such as cooling device).
This does have the minor side-effect that devfreq sysfs min_freq/
max_freq files now reflect the boost and idle clamping, as they show
(despite what they are documented to show) the aggregated min/max freq.
Fixing that in devfreq does not look straightforward after considering
that OPPs can be dynamically added/removed. However writes to the
sysfs files still behave as expected.
