From a269950405ab17ce3a604ddcd939709a4a7a747c Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Mon, 11 Jan 2010 14:33:40 +0200 Subject: [PATCH] OMAP: DSS2: move get_recommended_bpp() Move get_recommended_bpp() from omap_dss_device to omap_dss_driver. This is part of a larger patch-set, which moves the control from omapdss driver to the display driver.
