Hi Marc,
Here is the link to the whole series:
https://lore.kernel.org/linux-mips/20220519185125.11686-1-Dragan.Mladjenovic@syrmia.com/
but yes, having a full patchset in the inbox would be much better.

@Dragan, if you are still willing to get the series reviewed, please
add both Marc and me to the lists of the recipients of each patch and
resend. Of course make sure Thomas Bogendoerfer gets the whole series too.

@Dragan, as Marc already noted the sender's SoB must be added.
Who is Chao-ying and why do you need to add his SoB to each patch?
For instance you have the patch
"[PATCH 05/12] irqchip: mips-gic: Setup defaults in each cluster"
in this series which is stated being authored by Chao-ying but
you've also added Paul' SoB there. What did Paul do for that patch
development?
