However, the current Glue Code lacks support for SerDes routing and pinctrl handling, relying solely on correct settings in U-Boot. Clock settings for this SoC are managed by the ATF Firmware.
Please run scripts/checkpatch.pl and fix reported warnings. Some
warnings can be ignored, but the code here looks like it needs a fix.
Feel free to get in touch if the warning is not clear.
Read how commit msg should be wrapped.
Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):

That's totally unrelated to DTS. Do not mix independent work in one
patchset. This targets net-next, not SoC, so please send it as separate
patchset when net-next reopens, so after merge window.
