[PATCH v2 11/14] drm/msm/a6xx: Enable optional icc voting from OPP tables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On GMU-equipped GPUs, the GMU requests appropriate bandwidth votes
for us. This is however not the case for the other GPUs. Add the
dev_pm_opp_of_find_icc_paths() call to let the OPP framework handle
bus voting as part of power level setting.
