This patch series adds support for Qualcomm's On Chip MEMory (OCMEM)
that is needed in order to support some a3xx and a4xx-based GPUs
upstream. This is based on Rob Clark's patch series that he submitted
in October 2015 and I am resubmitting updated patches with his
permission. See the individual p

Some A3xx and A4xx Adreno GPUs do not have GMEM inside the GPU core and
must use the On Chip MEMory (OCMEM) in order to be functional. Add the
optional ocmem property to the Adreno Graphics Management Unit bindings.

The files a3xx_gpu.c and a4xx_gpu.c have ifdefs for the OCMEM support
that was missing upstream. Add two new functions (adreno_gpu_ocmem_init
and adreno_gpu_ocmem_cleanup) that removes some duplicated code.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct msm_gem_submit {
...
struct {

For a long time drm/msm had been abusing dma_map_* or dma_sync_* to
clean pages for buffers with uncached/writecombine CPU mmap'ings.
But drm/msm is managing it's own iommu domains, and really doesn't want
the additional functionality provided by various DMA API ops.
Let's just
The macro to generate a Bus Controller Manager (BCM) TCS command is used
by the interconnect driver but might also be interesting to other
drivers that need to construct TCS commands for sub processors so move
it out of the sdm845 specific file and into the header.
