[PATCH 1/2] video:omap2:dss: fix timings for VENC to match what omapdrm expects
From: H. Nikolaus Schaller <hidden>
Date: 2015-11-13 10:29:25
Also in:
dri-devel, linux-omap, lkml
Subsystem:
framebuffer layer, omap display subsystem and framebuffer support (dss2), the rest · Maintainers:
Helge Deller, Linus Torvalds
Otherwise check_timings fails and we get a "has no modes" message from xrandr. This fix makes the venc assume PAL and NTSC timings that match the timings synthetized by copy_timings_drm_to_omap() from omapdrm mode settings so that check_timings() succeeds. Tested on: BeagleBoard XM, GTA04 and OpenPandora Signed-off-by: H. Nikolaus Schaller <redacted> --- drivers/video/fbdev/omap2/dss/venc.c | 12 ++++++++++++ 1 file changed, 12 insertions(+)
