Tegra124 introduces a number of new peripheral clocks. This patch adds those
to the common peripheral clock code.

Don't you need to add AFC[0..5] in this patch and/or patch 5?

AFC[0..5] are reset only nodes afaik. Up to now, we haven't done that.
The goal is to include them once we move to the reset framework.

Cheers,

Peter.

No, we've always added clock entries for all reset-only clocks into the
clock driver. Since the port to the reset framework is not available
yet, we need to continue to do this. Otherwise, we won't be able to
upstream audio support.

The only clock which required this up to now was 'cop' (avp). Which is not
in upstream.

Peter.
