13:20 <jbrunet> There has been several PLL reliability issues with g12/sm1 SoC. HiFi, sys (dvfs) and now PCIe. There was no such problem with earlier generations.

13:20 <jbrunet> My guess is something is missing in the init sequence to help with the lock. I would not be surprised if was something like the self-adaption current module, like the a1

14:40 <rockosov> jbrunet: Per my understanding, self-adaption current module is new PLL feature starting from A1. But I suppose we can ask Amlogic about it directly or check vendor reference driver. We have production devices based on sm1/g12, I can try to confirm it internally.
