Subject: [PATCH v4 0/6] qcom: add OCMEM support

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/.

Brian Masney (4):
  dt-bindings: soc: qcom: add On Chip MEMory (OCMEM) bindings
  dt-bindings: display: msm: gmu: add optional ocmem property
  soc: qcom: add OCMEM driver
  drm/msm/gpu: add ocmem init/cleanup functions

Rob Clark (2):
  firmware: qcom: scm: add OCMEM lock/unlock interface
  firmware: qcom: scm: add support to restore secure config to
    qcm_scm-32
