From: Archit Taneja Date: Fri, 15 Jun 2012 02:09:47 +0000 (+0530) Subject: OMAPFB: Map the newly added omap_video_timings fields with fb sync flags X-Git-Tag: firefly_0821_release~3680^2~1437^2^2~110^2~6 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=783babf33f47c8d42e73900575dd9beea98fca40;p=firefly-linux-kernel-4.4.55.git OMAPFB: Map the newly added omap_video_timings fields with fb sync flags Use the newly added fields in omap_video_timings(hsync, vsync and data_enable logic levels and data, hsync and vsync latching related info) to configure/retrieve corresponding sync flags in fb_var_screeninfo and fb_videomode. Out of the new fields, hsync_level and vsync_level can be mapped to the fb sync flags FB_SYNC_HOR_HIGH_ACT and FB_SYNC_VERT_HIGH_ACT. When converting fb mode to omap_video_timings, the fields which don't have an equivalent parameter in fb are kept as the original values if the panel driver has a get_timings op, else they are set to default values.
