Add a utility function to dump HDMI core registers to
command line. This will facilitate debugging issues by
just calling this API wherever necessary.

Currently the sysfs nodes for receiving minimum
encryption level reside within the SDE HDMI driver.
Move the nodes to the misc hdcp driver so that they
are available for use for targets using DRM SDE driver.

otherwise let the client call the API to retry the number of

Currently submit ioctl getting blocked till the commands
gets added to ringbuffer incase inflight count is less
than context burst count. If the submit command happens
in GPU slumber state, it will add the GPU wakeup time to
submit IOCTL. This will add latency in preparing next frame
in CPU side. Defer commands submission to dispatcher worker,
if the GPU is in slumber state.

Currently the priority and other behavior of a command stream
is provided by the user application during submission and
the application is expected to internally maintain the settings
for each 'context' or 'rendering queue' and specify the correct
ones.
This works okay for simple cases but as applications become more
complex we will want to set context specific flags and do various
permisson checks to allow certain contexts to enable additional
privileges.
Add kernel-side submit queues to be analogous to 'contexts' or
'rendering queues' on the application side. Each file descriptor
instance will maintain its own list of queues. Queues cannot be
shared between file descriptors.
For backwards compatibility context id '0' is defined as a default
context specifying middle priority and no special flags. This is
intended to be the usual configuration for 99% of applications so
that a garden variety application can function correctly without
creating a queue. Only those applications requiring the specific
benefit of different queues need create one.
In addition to the basic infrastructure, allow the user to specify
the queue priority - this will be used in lieu of the legacy
flags to set priority during the submission. Only the master DRM
instance can set the highest priority, but all the others are open
to all processes.

When calling smmu mapping, if iova is specified directly by user, not
allocated dynamically in dma-mapping.c, smmu driver needs to provide
support for this. This is needed in early display case. In this scenario,
LK has set physical memory to display hardware for fetching, so if iova
is not explicitly specified in kernel, but instead dynamically produced
by "alloc_iova" in dma-mapping.c, display hardware has no chance to know
this new iova, then smmu fault will happen if enabling the iommu stage-1
translation.
To fix this smmu fault problem, add re-routing to the right path when
iova specified by user is not 0 in smmu map function.

commit e345da82bd6bdfa8492f80b3ce4370acfd868d95 upstream.
The builtin eDP panel in the HP zBook 17 G2 supports 10 bpc,
as advertised by the Laptops product specs and verified via
injecting a fixed edid + photometer measurements, but edid
reports unknown depth, so drivers fall back to 6 bpc.
Add a quirk to get the full 10 bpc.

commit 1b0f84380b10ee97f7d2dd191294de9017e94d1d upstream.
If the time to the next alarm is short enough, we could race with HW and
end up with an ~4 second delay until it triggers.
Fix this by checking again after we update HW.

commit 330bdf62fe6a6c5b99a647f7bf7157107c9348b3 upstream.
The idea here was to avoid having to "manually" program the HW if there's
a new earliest alarm. This was lazy and bad, as it leads to loads of fun
races between inter-related callers (ie. therm).
Turns out, it's not so difficult after all. Go figure ;)
