Pratham, can you reply to this please? I don't really understand what
your issue is for me to be able to help.
I apologize for not replying. Somehow, I did not notice the reply from
Dragan. :(
No worries, I saw the serial console log file in one of your messages,
which actually provided the answer to my question. :)
Since this patch was applied, an issue in the Rock 5B's DT has been
unearthed which now results in the kernel being unable to boot
properly.
Following is the relevant call trace from the UART capture:

Also, can you give the output of <debugfs>/devices_deferred for the
good vs bad case?
I can't provide you with requested output from the bad case, since the
kernel never moves past this to an initramfs rescue shell, but
following
is the output from v6.8.1 (**with aforementioned patch reverted**).
# cat /sys/kernel/debug/devices_deferred
fc400000.usb platform: wait for supplier /phy@fed90000/usb3-port
1-0022 typec_fusb302: cannot register tcpm port
fc000000.usb platform: wait for supplier /phy@fed80000/usb3-port
It seems that v6.8.2 works _without needing to revert the patch_. I
will
have to look into this sometime this week but it seems like
a8037ceb8964 (arm64: dts: rockchip: drop rockchip,trcm-sync-tx-only
from rk3588 i2s)
seems to be the one that fixed the root issue. I will have to test it
sometime later this week.
