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.

DRM: armada: fix missing DRM_KMS_FB_HELPER select Commit 92b6f89f6b8f (drm: Add separate Kconfig option for fbdev helpers) happened in parallel with the inclusion of Armada DRM into mainline, and so missed this update. Add the necessary select statement to avoid build errors. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

help
Support the "LCD" controllers found on the Marvell Armada 510
devices. There are two controllers on the device, each controller
supports graphics and video overlays.
This driver provides no built-in acceleration; acceleration is
performed by other IP found on the SoC. This driver provides
kernel mode setting and buffer management to userspace.
