From 8af6ff0107f0720b8fbf4feca7031d3e36c2fa11 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Mon, 5 Sep 2011 16:48:27 +0530 Subject: OMAP: DSS2: DSI Video mode support Add initial support for DSI video mode panels: - Add a new structure omap_dss_dsi_videomode_data in the member "panel" in omap_dss_device struct. This allows panel driver to configure dsi video_mode specific parameters. - Configure basic DSI video mode timing parameters: HBP, HFP, HSA, VBP, VFP, VSA, TL and VACT. - Configure DSI protocol engine registers for video_mode support. - Introduce functions dsi_video_mode_enable() and dsi_video_mode_disable() which enable/disable video mode for a given virtual channel and a given pixel format type. Things left for later - Add functions to check for errors in video mode timings provided by panel. - Configure timing registers required for command mode interleaving.
