Is the difference really a matter of SoCs, or is it because the FSD SoC
uses a different version of the IP ?
I also suspect that the "phy" clock was added by mistake, and isn't
needed in NXP SoCs. Could you please check and confirm if the v3.3 and
v3.6.3 versions of the IP have an input PHY clock ?
