There are three cases of power domain management on supported platforms:
1) CAMSS on MSM8916, where a single VFE power domain is operated outside
of the camss device driver,
2) CAMSS on MSM8996 and SDM630/SDM660, where two VFE power domains are
managed separately by the camss device driver, the power domains are
linked and unlinked on demand by their functions vfe_pm_domain_on()
and vfe_pm_domain_off() respectively,
3) CAMSS on SDM845 and SM8250 platforms, and there are two VFE power
domains and their parent power domain TITAN_TOP, the latter one
shall be turned on prior to turning on any of VFE power domains.
Due to a previously missing link between TITAN_TOP and VFEx power domains
in the latter case, which is now fixed by [1], it was decided always to
turn on all found VFE power domains and TITAN_TOP power domain, even if
just one particular VFE is needed to be enabled or none of VFE power
domains are required, for instance the latter case is when vfe_lite is in
use. This misusage becomes more incovenient and clumsy, if next generations
are to be supported, for instance CAMSS on SM8450 has three VFE power
domains.
The change splits the power management support for platforms with TITAN_TOP
parent power domain, and, since 'power-domain-names' property is not
present in camss device tree nodes, the assumption is that the first
N power domains from the 'power-domains' list correspond to VFE power
domains, and, if the number of power domains is greater than number of
non-lite VFEs, then the last power domain from the list is the TITAN_TOP
power domain.

The change to dynamically allocated power domains neglected a case of
CAMSS on MSM8916 platform, where a single VFE power domain is neither
attached, linked or managed in runtime in any way explicitly.
This is a special case and it shall be kept as is, because the power
domain management is done outside of the driver, and it's very different
in comparison to all other platforms supported by CAMSS.

The dvb-core tries to sync the releases of opened files at
dvb_dmxdev_release() with two refcounts: dvbdev->users and
dvr_dvbdev->users. A problem is present in those two syncs: when yet
another dvb_demux_open() is called during those sync waits,
dvb_demux_open() continues to process even if the device is being
closed. This includes the increment of the former refcount, resulting
in the leftover refcount after the sync of the latter refcount at
dvb_dmxdev_release(). It ends up with use-after-free, since the
function believes that all usages were gone and releases the
resources.
This patch addresses the problem by adding the check of dmxdev->exit
flag at dvb_demux_open(), just like dvb_dvr_open() already does. With
the exit flag check, the second call of dvb_demux_open() fails, hence
the further corruption can be avoided.
Also for avoiding the races of the dmxdev->exit flag reference, this
patch serializes the dmxdev->exit set up and the sync waits with the
dmxdev->mutex lock at dvb_dmxdev_release(). Without the mutex lock,
dvb_demux_open() (or dvb_dvr_open()) may run concurrently with
dvb_dmxdev_release(), which allows to skip the exit flag check and
continue the open process that is being closed.
CVE-2022-41218 is assigned to those bugs above.

aspeed supports differential jpeg format which only compress the parts
which are changed. In this way, it reduces both the amount of data to be
transferred by network and those to be decoded on the client side.
2 new ctrls are added:
* Aspeed HQ Mode: to control aspeed's high quality(2-pass) compression mode
This only works with yuv444 subsampling.
* Aspeed HQ Quality: to control the quality of aspeed's HQ mode
only useful if Aspeed HQ mode is enabled
Aspeed JPEG Format requires an additional buffer, called bcd, to store
the information about which macro block in the new frame is different
from the previous one.
To have bcd correctly working, we need to swap the buffers for src0/1 to
make src1 refer to previous frame and src0 to the coming new frame.

[hverkuil: fix logging dma_addr_t, use %pad for that]
This introduces support for the Aspeed JPEG format, where the new frame
can refer to previous frame to reduce the amount of compressed data.
The concept is similar to I/P frame of video compression. It will
compare the new frame with previous one to decide which macroblock's
data is changed, and only the changed macroblocks will be compressed.
This Aspeed JPEG format is used by the video engine on Aspeed platforms,
which is generally adapted for remote KVM.
