[PATCH 04/21] drm/msm/dpu: get DSPP blocks directly rather than through RM
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Wed Mar 24 15:00:07 UTC 2021
Each DSPP block is tied to a single LM. No LMs can share single DSPP
block. So there is no need to handle DSPP blocks through all resource
allocation/deallocation/assignment, just receive DSPP block as a part of
LM hardware instance.
