From 9b4a5716ef54bbf2f57c75f790b12fc63a4be640 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Wed, 8 Aug 2012 16:56:06 +0530 Subject: [PATCH] OMAPDSS: SDI: Maintain our own timings field in driver data The SDI driver currently relies on the timings in omap_dss_device struct to configure the DISPC accordingly. This makes the SDI interface driver dependent on the omap_dss_device struct. Make the SDI driver data maintain it's own timings field. The panel driver is expected to call omapdss_sdi_set_timings() to set these timings before the panel is enabled. Make the SDI panel driver configure the new timings is the omap_dss_device struct(dssdev->panel.timings). The SDI driver is responsible for maintaining only it's own copy of timings.
