+description:
+  The AST2600 and later contain two identical FSI masters. They share a
+  clock and have a separate interrupt line and output pins.

+  compatible:
+    enum:
+      - "aspeed,ast2600-fsi-master"
+      - "aspeed,ast2700-fsi-master"
This wasn't tested. No quotes. Do you see any other example like this?


Strangely this passes make dt_binding_check for me... And Rob's bot didn't seem to catch it either. Just an oversight, I'll fix it.

This goes after required:


Ack.

No children?


Ack, I'll add one.
