SYS_CTRL register. E.g. IPP_RST_N shouldn't be touched accidently.

What's the status of this? I can't find it e.g. in linux-next?

Does anybody like to help to apply this?

Looks like you didn't answer Shawn's question yet, could you please?

I'm wondering if it fixes any issue in real life?

I wasn't aware that this questions blocks applying that patch. I think I've answered Shawn's question in a private mail: Using RST_N doesn't work if the controller's IPP_RST_N bit is touched accidentally, i.e. if a reset is asserted if it shouldn't.

Many thanks and best regards

Dirk
