In particular, while adding the MT8195 compatible to the mediatek,ufs binding, I noticed that it was allowing just one clock, completely ignoring the optional ones, including the crypt-xxx clocks, all of the optional regulators, and other properties. Between all the other properties, two are completely useless, as they are there just to activate features that, on SoCs that don't support these, won't anyway be activated because of missing clocks or missing regulators, or missing other properties; as for the other vendor-specific properties, like ufs-disable-ah8, ufs-broken-vcc, ufs-pmc-via-fastauto, since the current merge window is closing, I didn't do extensive research so I've left them in place but didn't add them to the devicetree binding yet. The plan is to check those later and eventually give them a removal treatment, or add them to the bindings in a part two series. For now, at least, this is already a big improvement. P.S.: The only SoC having UFSHCI upstream is MT8183, which only has just one clock, and *nothing else* uses properties, clocks, etc that were renamed in this cleanup. Cheers!
