[Intel-gfx] [PATCH 4/4 V2] drm/i915: Enable PAL and SECAM format for SDVO-TV
ling.ma at intel.com

Mon Jul 13 11:57:57 CEST 2009
Currently SDVO TV only support NTSC-M format. In this patch
we introduce PAL and SECAM formats available and create seting-format
property at init time. When user dynamically chose preferred
format by xrandr command, it will refine all modelines
provided by SDVO device, then instruct SDVO device to execute.
