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
Currently OMAP2 and 3 share the same omap_hwmod_class and
omap_hwmod_class_sysconfig for dispc. However, OMAP3 has sysconfig
bits that OMAP2 doesn't have, so we need to split those structs into
OMAP2 and OMAP3 specific versions.
This patch only splits the structs, without changing the contents.
dispc's sysc_flags is missing SYSC_HAS_ENAWAKEUP flag. This seems to
cause SYNC_LOST errors from the DSS when the power management is
enabled.
This patch adds the missing SYSC_HAS_ENAWAKEUP flag. Note that there are
other flags missing also (clock activity, DSI's sysc flags), but as they
are not
omapdss doesn't work properly on system suspend. The problem seems to be
the fact that omapdss uses pm_runtime_put() functions when turning off
the hardware, and when system suspend is in process only sync versions
are allowed.
Using non-sync versions normally and sync versions when suspending
