Hi Markus,
Attachment 0003 is the proposal I make for the clamp protection issue
we last discussed and others are some dependency patch. Since smi has
have two type of protection but in different stage. So I eventually
decide to separate it. May you help test these patch on mt8365, I test
it a bit on mt8188 and it work fine. Still any advice and modification
are welcome!
SMI protection type
1. clamp
2. bus protection
For example: power on
"clamp protection enable" (smi, with clamp flag)
-> regulator enable
...
-> clamp protection disaled (smi, with clamp flag)
-> bus protection disabled (smi -> infra)
For example: power off
"clamp protection enable" (smi, with clamp flag)
-> bus protection enable (infra -> smi)
Best Regards,
