2015-07-15drm/armada: fix gem object free after failed prime importRussell King1-2/+3
Fix the gem object freeing after a partial import of a dma buffer, eg, one which has been imported, but not mapped. This was provoking a warning from the dma_buf code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2015-04-21dma-buf: cleanup dma_buf_export() to make it easily extensibleSumit Semwal1-2/+8
At present, dma_buf_export() takes a series of parameters, which makes it difficult to add any new parameters for exporters, if required. Make it simpler by moving all these parameters into a struct, and pass the struct * as parameter to dma_buf_export(). While at it, unite dma_buf_export_named() with dma_buf_export(), and change all callers accordingly.

2014-07-09dma-buf: use reservation objectsMaarten Lankhorst1-1/+1
This allows reservation objects to be used in dma-buf. it's required for implementing polling support on the fences that belong to a dma-buf.

2014-05-27drm/armada: use shmem helpers if possibleDavid Herrmann1-3/+1
shmem_read_mapping_page() uses mapping_gfp_mask(mapping) as default gfp mask. No reason to use shmem_read_mapping_page_gfp() directly if we want the default behavior.

2013-12-11DRM: Armada: prime refcounting bug fixRussell King1-1/+1
Commit 011c2282c74d changed the way refcounting on imported dma_bufs works, and this hadn't been spotted while forward-porting Armada. Reflect the changes in that commit into the Armada driver.

2013-10-12DRM: Armada: Add Armada DRM driverRussell King1-0/+611
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.
