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.
The question is if a specific driver implementation should determine what the DT requires or the other way round. I don't know...
I did interpret Rob's comment differently: there was
- "clock-names" Must be "bus_clk"
and he did say:
'clk' is redundant. How about 'ahb'?
So I thought he refers to the _clk suffix?
and he said to my first try: ---
- clock-names:
- items:
- const: bus_clk
My prior comment still applies.
Also, for a single clock, you don't really need a name. ---
