I think if you chose the ordering in the r8a7795, then you only have to
adjust/correct the ordering in the r8a7796 and r8a77965 ...
Especially as you haven't changed the ordering of r8a77970, and r8a77980
which have the status after the vsps entry.

I'm not sure the vsps should be below the status = disabled line.
I'd have this as:
clock-names...
vsps...
renesas,cmms...
<blank line>
status...
<blank line>
ports...

I think these should be separated by comma's to show they are separate
references, or references to separate phandles or such.
The only precedence I could find was in pmu_a53:
interrupt-affinity = <&a53_0>, <&a53_1>, <&a53_2>, <&a53_3>;

Aha, yes, I'd move this vsps rather than the one at r8a7795, which I'd
consider to be more 'correct'.

Again, I'd consider this the wrong sort order, due to the status'
importance. I wouldn't hide it in the middle.
