From 59685fdfac6d7343c4047f2acfbc5bce8971b0f9 Mon Sep 17 00:00:00 2001 From: Vikash Garodia Date: Tue, 12 Apr 2022 14:15:11 +0100 Subject: [PATCH] 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.
