With v6.1.72-cip13 + Zynq UltraScale+ MPSoC ZCU102, we observed that
Ethernet does not work when it's speed is 100Mbps.
This issue happens after d94c14f6fa34f2b8b33e5957f5b8dfb5aaf56b1e is
backported to the clk framework, which is not a part of linux-6.1.y
and probably is one of the dependencies of versa3 clk generator support
for Renesas SoCs. See the patch series "Add versa3 clk generator support".

In mainline, a fix for the backport commit above is provided:
be8fa5fd0a48fd2decc4de81ffe72bb3ceacecd9.
This should be applied to linux-6.1.y-cip as well.
With v6.1.72-cip13 + this patch, we confirmed the ZCU102 Ethernet
works at 100Mbps.
