[PATCH v2 04/22] drm/msm/dpu: switch RM to use crtc_id rather than enc_id for allocation
Jessica Zhang

Tue Sep 24 22:59:20 UTC 2024
From: Dmitry Baryshkov <dmitry.baryshkov at linaro.org>
Up to now the driver has been using encoder to allocate hardware
resources. Switch it to use CRTC id in preparation for the next step.
