I think it's UBWC encoder version, see 
https://git.codelinaro.org/clo/la/platform/vendor/opensource/display-drivers/-/blob/display-kernel.lnx.5.15.1.r17-rel/msm/sde/sde_hw_top.c?ref_type=heads#L357

This is a part of 
https://patchwork.freedesktop.org/patch/538279/?series=118074&rev=1

(no, you don't have to rebase on that patchset, it is not reviewed yet).
