Subject: [PATCH] media: aspeed: fix mode-detect always timeout at 2nd run
Date: Tue, 2 Nov 2021 15:13:37 +0800 [thread overview]
Message-ID: <20211102071337.5983-1-jammy_huang@aspeedtech.com> (raw)
aspeed_video_get_resolution() will try to do res-detect again if the
timing got in last try is invalid. But it will always timeout because
VE_SEQ_CTRL_TRIG_MODE_DET only cleared after 1st mode-detect.
To fix the problem, just clear VE_SEQ_CTRL_TRIG_MODE_DET before set in
aspeed_video_enable_mode_detect().
