[PATCH v6 0/7] qcom: add OCMEM support

[Brian Masney]

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 patches for the changelog.

This was tested with the GPU on a LG Nexus 5 (hammerhead) phone and
this will work on other msm8974-based systems. For a summary of what
currently works upstream on the Nexus 5, see my status page at
https://masneyb.github.io/nexus-5-upstream/.

Changes since v5:
- Rename ocmem device tree property to sram

See individual patches for changelogs for previous versions.
