I don't see any mention of it.
Nevermind, found it in mmc-controller.yaml. But I think this is to work around some problem with the clk driver picking lower speeds than requested? That has been fixed on the clk driver side (see commit like 148ddaa89d4a "clk: qcom: gcc-sc7180: Use floor ops for the correct sdcc1 clk") so ideally this property can be omitted.
