Subject: [PATCH 14/17] drm/msm/a8xx: Add support for Adreno 840 GPU
Adreno 840 present in Kaanapali SoC is the second generation GPU in
A8x family. It comes in 2 variants with either 2 or 3 Slices. This is
in addition to the SKUs supported based on the GPU FMAX.
Add the necessary register configurations to the catalog and enable
support for it.
