Subject: [PATCH 1/1] venus: Enable sufficient sequence change support for sc7180 and Fix for Decoder STOP command issue.
Date:   Tue, 15 Nov 2022 17:42:37 +0530
Message-Id: <20221115121237.28361-2-quic_vboma@quicinc.com>
In-Reply-To: <20221115121237.28361-1-quic_vboma@quicinc.com>

Precedence: bulk

From: Viswanath Boma <quic_vboma@quicinc.com>

For VP9 bitstreams, there could be a change in resolution at interframe,
for driver to get notified of such resolution change, enable the property in video firmware.
Also, EOS handling is now made same in video firmware across all V6 SOCs,
hence above a certain firmware version, the driver handling is made generic for all V6s
