Hi Amit,

Thanks for fixing this.

In fact, I assumed I fixed things with commit 978fa436231a ("drivers:
firmware: psci: unify enable-method binding on ARM {64,32}-bit systems"),
but I was wrong. I left quite a few instances including juno dtbs.

For all the above files,

How do you plan to merge ? I prefer if you can send it via arm-soc as
fixes for this cycle with all the necessary acks. Otherwise you may have
to split this to send via platform maintainers which is bit mundane.
