[PATCH 1/3] drm/msm/dpu: drop SSPP's SRC subblock
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Sat Apr 22 00:08:37 UTC 2023
The src_blk declares a lame copy of main SSPP register space. It's
offset is always 0. It's length has been fixed to 0x150, while SSPP's
length is now correct. Drop the src_blk and access SSPP registers
without additional subblock lookup.
