Merge tag 'omapdss-for-3.7' of git://gitorious.org/linux-omap-dss2/linux into fbdev-next
Omapdss driver changes for the 3.7 merge window. Notable changes: * Basic writeback support for DISPC level. Writeback is not yet usable, though, as we need higher level code to actually expose the writeback feature to userspace. * Rewriting the omapdss output drivers. We're trying to remove the hard links between the omapdss and the panels, and this rewrite work moves us closer to that goal. * Cleanup and restructuring patches that have been made while working on device tree support for omapdss. Device tree support is still some way ahead, but these patches are good cleanups in themselves. * Basic OMAP5 DSS support for DPI and DSI outputs. * Workaround for the problem that GFX overlay's fifo is too small for high resolution scenarios, causing underflows. * Cleanups that remove dependencies to omap platform code.
