Reusing the Big DRM Lock just leaks, and the few things left that
dev->struct_mutex protected are very well contained - it's just the
linear drm_mm manager.

With this armada is completely struct_mutex free!

v2: Convert things properly and also take the lock in
armada_gem_free_object, and remove the stale comment (Russell).

DRM: Armada: convert to use simple_open() 2013-11-06T02:02:36+00:00 Duan Jiong duanj.fnst@cn.fujitsu.com 2013-11-01T05:45:05+00:00 a276d6ce8a9b146831f3f14b327f74df446a794a This removes an open coded simple_open() function and replaces file operations references to the function with simple_open() instead.

DRM: Armada: Add Armada DRM driver 2013-10-12T09:13:40+00:00 Russell King rmk+kernel@arm.linux.org.uk 2012-08-15T12:59:49+00:00 96f60e37dc66091bde8d5de136ff6fda09f2d799 This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent.
