Subject: [PATCH 0/2] drm: tda998x: Fix a couple of problems
Date: Sat, 29 Nov 2014 09:12:51 +0100 [thread overview]
Message-ID: <cover.1417248771.git.moinejf@free.fr> (raw)
1)
The HDMI registers of the tda998x chips are accessed by pages.
As these HDMI registers may be accessed from different tasks
(video, irq/workqueue, and soon audio), the page register setting
must be protected.
2)
On HDMI reconnect (cable plug-in), the EDID is read too early and
this raises a EDID read timeout. Delaying a bit the connect event
fixes the problem.
