Cover letter [PATCH 0/2] drm: tda998x: Fix a couple of problems
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.
