hence above a certain firmware version, the driver handling is

Having "Do abc. Also do defgh." is a clear sign that this patch should
be split into two.
I agree, it could have split into patches. The patch introduces way to
store venus firmware
version and take some decision for various version. For ex. here STOP
handling and enabling
DRC event for specific firmware revision and onwards. Since both the
handling was primarily
dependent of firmware version, and since the handlings were smaller, it
was combined as single
patch. Let me know, if you have any further review comments, else, will
raise a new version with
2 patches probably.

Let me repeat my question from v3:
Is it really specific just to sc7180 or will it be applicable to any
other platform using venus-5.4 firmware?
The HFI "HFI_PROPERTY_PARAM_VDEC_ENABLE_SUFFICIENT_SEQCHANGE_EVENT" is
implemented
only for sc7180. Calling this for any other venus-5.4 would error out
the session with error as
unsupported property from firmware.
