Subject: [PATCH 0/3] OMAP: DSS PM fixes
Date: Mon, 23 Jan 2012 12:15:27 +0000	[thread overview]
Message-ID: <1327320930-14550-1-git-send-email-tomi.valkeinen@ti.com> (raw)

Here are two fixes to get DSS work better with PM on OMAP3.

The first two patches fix the missing SYSC_HAS_ENAWAKEUP flag, which removes
the SYNC_LOST problem.

The third patch changes omapdss to use pm_runtime_put_sync functions, which
fixes the system suspend.

I've tested both only on v3.3-rc1, OMAP3 Overo. I get problems on system
suspend from TWL and MTD drivers (also without my patches =), but disabling MTD
and ignoring TWL errors shows that the warning from omapdss has disappeared,
and I get an image on the screen on resume.

The two fixes are independent, so either I can take them through dss tree (with
appropriate Acks), or the hwmod patches can go through some other tree.

The fixes should also work directly on v3.2, even though I haven't tested them
yet.
