Merge tag 'drm-msm-next-2018-12-12' of git://people.freedesktop.org/~robclark/linux into drm-next
This time around, seeing some love for some older hw: - a2xx gpu support for apq8060 (hp touchpad) and imx5 (headless gpu-only mode) - a2xx gpummu support (a2xx was pre-iommu) - mdp4 display support for apq8060/touchpad For display/dpu: - a big pile of continuing dpu fixes and cleanups On the gpu side of things: - per-submit statistics and traceevents for better profiling - a6xx crashdump support - decouple get_iova() and page pinning.. so we can unpin from physical memory inactive bo's while using softpin to lower cpu overhead - new interface to set debug names on GEM BOs and debugfs output improvements - additional submit flag to indicate buffers that are used to dump (so $debugfs/rd cmdstream dumping is useful with softpin + state-objects) Signed-off-by: Dave Airlie <airlied@redhat.com> From: Rob Clark <robdclark@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/CAF6AEGvVvLPD9_Z4kyfGe98Y--byj6HbxHivEYSgF7Rq7=bFnw@mail.gmail.com

Note that you need to list the less specific "qcom,adreno" (since this
is what the device is matched on), in addition to the more specific
with the chip-id.
+ If "amd,imageon" is used, there should be no top level msm device.
- reg: Physical base address and length of the controller's registers.
- interrupts: The interrupt signal from the gpu.
- clocks: device clocks
