These interrupt names don't match the binding you've posted (GPU, MMU, JOB are upper case here, lower case in the binding). Also EVENT and PWR are not mentioned in the binding - should they be?
I know there are differences here between kbase's requirements and the existing upstream bindings (case specifically), but I haven't seen a binding containing EVENT and PWR before.

Thanks for your comment. Yes, the EVENT and PWR should be removed. And the rest of interrupt names are corrected to lower case.
Please check my updated version 4 for this. https://lore.kernel.org/patchwork/patch/1363862/
