Is this function used by omapdrm? I can't see it being used in the later patches.

Yes, it will be used by omapdrm (or, at least, it can be used). I guess some of these patches don't quite make sense without the final compat-layer work, and modifications to omapdrm. But mostly the "doesn't make sense" parts are probably just exposing functions that aren't used yet. Tomi

Add new dispc function, dispc_ovl_enabled(). This returns if the overlay enable bit is set in the registers. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> --- drivers/video/omap2/dss/dispc.c | 5 +++++ drivers/video/omap2/dss/dss.h | 1 + 2 files changed, 6 insertions(+)
