GEN9_PIPE_PLANE_FLIP_DONE() only works for planes 1-4. Extend
it handle planes 5-7 as well. Somewhat annoyingly the bits are
spread around into two distinct clumps.
Currently this doesn't achieve anything, but if we ever extend
async flip support to more than just the first plane then we'll
need this.

This warning is triggered by a check in the function
resource_get_opp_heads_for_otg_master that validates if the request
operation is in a master OTG pipe; if not, the warning above is
displayed. In other words, another part of the code might be calling
this function in a non-OTG master pipe context, resulting in the log
message.
The reason the ASSERT was triggered is that the current state wasn't
updated after applying the context to the hardware. This means that the
update_dsc_for_odm_change might be called from a non-OTG-MASTER. To
prevent this, it's crucial to check if the current reference is pointing
to an OTG master before operate in the old OTG master reference. If it's
not, the function must set the old OTG reference to NULL and avoid
calling resource_get_opp_heads_for_otg_master before the context is
updated.

The histogram support mixes _irqsave and _irq, causing the following
smatch warning:
drivers/media/platform/renesas/vsp1/vsp1_histo.c:153 histo_stop_streaming()
warn: mixing irqsave and irq
The histo_stop_streaming() calls spin_lock_irqsave() followed by
wait_event_lock_irq(). The former hints that interrupts may be disabled
by the caller, while the latter reenables interrupts unconditionally.
This doesn't cause any real bug, as the function is always called with
interrupts enabled, but the pattern is still incorrect.
Fix the problem by using spin_lock_irq() instead of spin_lock_irqsave()
in histo_stop_streaming(). While at it, switch to spin_lock_irq() and
spin_lock() as appropriate elsewhere.

The adv748x-csi2 driver configures the CSI-2 transmitter to
automatically infer the image stream format from the connected
frontend (HDMI or AFE).
Setting a new format on the subdevice hence does not actually control
the CSI-2 output format, but it's only there for the purpose of
pipeline validation.
However, there is currently no validation that the supplied media bus
code is valid and supported by the device.
With the introduction of enum_mbus_codes a list of supported format is
now available, use it to validate that the supplied format is correct
and use the default UYVY8 one if that's not the case.
