Message-ID: <1649769311-22622-3-git-send-email-quic_vgarodia@quicinc.com> Date: Tue, 12 Apr 2022 18:45:11 +0530 From: Vikash Garodia <quic_vgarodia@...cinc.com> To: <linux-media@...r.kernel.org>, <stanimir.varbanov@...aro.org> CC: <linux-kernel@...r.kernel.org>, <quic_vgarodia@...cinc.com> Subject: [PATCH v2 2/2] media: venus: vdec: ensure venus is powered on during stream off Video decoder driver auto-suspends the hardware if there is no exchange of command or response for certain amount of time. In auto suspended state, it becomes mandatory to power on the hardware before requesting it to process a command. The fix ensures the hardware is powered on during stop streaming.
