From a8d5e41cef43bd740ca7c56ff316bdee30040a91 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Mon, 25 Jun 2012 12:26:38 +0530 Subject: OMAPDSS: Add some new fields to omap_video_timings Some panel timing related fields are contained in omap_panel_config in the form of flags. The fields are: - Hsync logic level - Vsync logic level - Data driven on rising/falling edge of pixel clock - Output enable/Data enable logic level - HSYNC/VSYNC driven on rising/falling edge of pixel clock Out of these parameters, Hsync and Vsync logic levels are a part of the timings in the Xorg modeline configuration. So it makes sense to move the to omap_video_timings. The rest aren't a part of modeline, but it still makes sense to move these since they are related to panel timings. These fields stored in omap_panel_config in dssdev are configured for LCD panels, and the corresponding LCD managers in the DISPC_POL_FREQo registers. Add the above fields in omap_video_timings. Represent their state via new enums. Add these parameters to the omap_video_timings instances in the panel drivers. Keep the corresponding IVS, IHS, IPC, IEO, RF and ONOFF flags in omap_panel_config for now. The struct will be removed later.
