Subject: [PATCH 0/2] OMAPDSS: DISPC: Improvements to DIGIT sync signal selection
Date: Fri, 27 Jul 2012 19:21:35 -0500	[thread overview]
Message-ID: <1343434897-8444-1-git-send-email-ricardo.neri@ti.com> (raw)

Hello,

DSS code wrongly assumes that VENC is always available as source for the external
sync signal for the display controller DIGIT channel. One cannot blindly
rely only on the value of DSS_CONTROL register as certain processors may not
have VENC (e.g., OMAP5).

These patches add logic to correctly set/get the sync signal based on the
available displays in the DIGIT channel.

For the HDMI driver, handle the error in the selection of the source.

BR,

Ricardo
