This series includes the changes to
- add firmware version based check to enable/disable some feature.
- add support of new HFI to notify sequence change event to
driver during resolution change at interframe.
- use firmware version based check to fix EOS handling for different
firmware versions.
With this series, divided the previous version [1] into
multiple patches as suggested in review comments.
[1] https://patchwork.kernel.org/project/linux-media/list/?series=733169
changes since v3:
Improved design for reading firmware version for all supported
firmwares (Konrad)
change since v2:
added firmware version based check for all supported firmwares.
added return value check of scanf.
addressed other review comments.
change since v1:
addressed coding comments.
Dikshita Agarwal (3):
venus: add firmware version based check
venus: enable sufficient sequence change support for vp9
venus: fix EOS handling in decoder stop command

2.7.4
VP9 supports resolution change at interframe.
Currenlty, if sequence change is detected at interframe and
resources are sufficient, sequence change event is not raised
by firmware to driver until the next keyframe.
This change add the HFI to notify the sequence change in this
case to driver.
