[RESEND PATCH 0/2] GEM CMA DMA-BUF support

Hello,

Upon Rob Clark's request here's a repost of two patches that implement GEM CMA objects import and export as dma-buf file handles.

The code is based on the Exynos DRM DMA-BUF implementation. The exporter role has been successfully tested with the Renesas R-Car DU driver.

Laurent Pinchart (2): drm: GEM CMA: Split object creation into object alloc and DMA memory alloc drm: GEM CMA: Add DRM PRIME support
