What was the visible effect of this bug, if any? Do you know why the minimum has that particular value? The Fixes tag is wrong; it should be: Fixes: 433f9a57298f ("arm64: dts: sdm845: add Inline Crypto Engine registers and clock") - Eric

Minimum frequency of the "ice_core_clk" should be 75MHz as specified in the downstream vendor devicetree.
