Yes, that's the question. The good news is below two patch series 
already got reviewed.

- gcc: 
https://lore.kernel.org/all/20251126-gcc_kaanapali-v3-v4-0-0fe73d6898e9@oss.qualcomm.com/
- ipcc: 
https://lore.kernel.org/all/20251031-knp-ipcc-v3-0-62ffb4168dff@oss.qualcomm.com/ 

Can I have your review-by tag after fix the order of the mentioned node?
Then I will send a new version with the tag after the dependency is 
being cleaned.

Thanks,
Jie
