From 5ae9eaa6dbeccab781cd9312371fad801a5ba1a2 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Thu, 21 Jun 2012 09:41:10 +0530 Subject: OMAPDSS: Remove passive matrix LCD support (part 2) Remove OMAP_DSS_LCD_TFT as a omap_panel_config flag. We don't support passive matrix displays any more. Remove this flag from all the panel drivers. Force the display_type to OMAP_DSS_LCD_DISPLAY_TFT in the interface drivers.

Remove acbi and acb fields in omap_dss_device and their configuration in panel drivers. Don't program these fields in DISP_POL_FREQo register any more. The panel driver for sharp-ls037v7dw01, and the panel config for Innolux AT070TN8 in generic dpi panel driver set acb to a non zero value. This is most likely carried over from the old omapfb driver which supported passive matrix displays.

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.
