Series drm/msm: adreno: add support for DDR bandwidth scaling via GMU | expand

Commit Message

Neil Armstrong Nov. 28, 2024, 10:25 a.m. UTC
Now all the DDR bandwidth voting via the GPU Management Unit (GMU)
is in place, declare the Bus Control Modules (BCMs) and the
corresponding parameters in the GPU info struct and add the
GMU_BW_VOTE feature bit to enable it.
