[PATCH 0/3] i2c: atr: allow usage of nested ATRs

Posted by Cosmin Tanislav 1 year ago

For upcoming GMSL drivers, we need to be able to use nested ATRs.
The deserializer changes the address of the serializers, and can only
do that for the serializers, while the serializers have proper address
translation hardware, and can translate the address of its children.

This series depends on:
