Why do you need phandles for these things, can they not be looked up by
compatible? (e.g. multiple devices on one SoC).

ecap is another peripheral similar to IEP in ICSSM/ICSSG. We have created a
separate driver for possible reuse with ICSSG in future.

That's not an answer to my question.

We can use compatible if we have only one instance of a peripheral in the SOC. 
On the AM57x SOC we have two identical ICSS instances(ICSS1 and ICSS2). So we 
use phandles to differentiate between the two instances. Currently this patch 
series adds support for ICSS2 instance on the AM57x SOC. Support for ICSS1 instance 
will be added in subsequent patches.

Cool, that's an acceptance answer, thanks.
