Daniel Vetter	0b8ebeacf5	drm/armada: use a private mutex to protect priv->linear ... 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).

Duan Jiong	a276d6ce8a	DRM: Armada: convert to use simple_open() ... This removes an open coded simple_open() function and replaces file operations references to the function with simple_open() instead.

Russell King	96f60e37dc	DRM: Armada: Add Armada DRM driver ... 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.
