[RFC PATCH] drm/msm/dpu: move UBWC/memory configuration to separate struct

Dmitry Baryshkov dmitry.baryshkov at linaro.org
Mon Jan 23 07:13:04 UTC 2023


UBWC and highest bank settings differ slightly between different DPU
units of the same generation, while the dpu_caps and dpu_mdp_cfg are
much more stable. To ease configuration reuse move ubwc_swizzle and
highest_bank_bit data to separate structure.
