This patch brings support for the JZ4780 efuse. Currently it only exposes a read only access to the entire 8K bits efuse memory.

as Rob said: probably not needed, since it is a single clock, and the driver uses devm_clk_get(dev, NULL), so it should be prepared for that without any extra work.
+required:
- compatible
- reg
- clock-names
so it is not required here (but "- clocks" (not "- clock") as said in earlier mail).

and not required here.
