[PATCH v3 2/2] drm/tinydrm: Switch from CMA to shmem buffers

This move makes tinydrm useful for more drivers. tinydrm doesn't need continuous memory, but at the time it was convenient to use the CMA library. The spi core can do dma on is_vmalloc() addresses making this possible. Cc: David Lechner Signed-off-by: Noralf Trønnes --- drivers/gpu/drm/tinydrm/

[PATCH v3 0/2] drm: Add shmem GEM library
