Numbering also conflicts with one of my patches:

https://patchwork.kernel.org/patch/10940303/

The conflict is easy to resolve but I don't mind resending if your 
patches get accepted first. If should probably resend anyway to also add 
gic clk to 8mq.

For series:

Thanks, I did NOT notice this, feel free if want me to resend the patch set, both
the GPIO clock and SNVS clock patch series.

Thanks,
Anson.
