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.

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.
