[PATCH v3 1/1] UPSTREAM: drm/bridge: it6505: fix hibernate to resume no display issue

From: kuro chung ITE added a FIFO reset bit for input video. When system power resume, the TTL input of it6505 may get some noise before video signal stable and the hardware function reset is required. But the input FIFO reset will also trigger error interrupts of output module rising. Thus

[PATCH v11] drm/bridge: it6505: fix hibernate to resume no display issue

From: Kuro Chung When the system power resumes, the TTL input of IT6505 may experience some noise before the video signal stabilizes, necessitating a video reset. This patch has been implemented to prevent a loop of video error interrupts, which can occur when a video reset in the video FIFO
