I missread the original bindings document and somehow missed
warnings emitted by dtbs_check. I now think the compat property should be
described as:
compatible:
oneOf:
- items:
- enum:
- renesas,thermal-r8a73a4 # R-Mobile APE6
- renesas,thermal-r8a7779 # R-Car H1
- const: renesas,rcar-thermal # Without thermal-zone
- items:

- renesas,thermal-r8a7793 # R-Car M2-N
- const: renesas,rcar-gen2-thermal # With thermal-zone
- const: renesas,rcar-thermal # Without thermal-zone

There may be any number of register blocks present and the
"# Address range of the thermal registers." is very generic.
So I think the above should be updated to:
reg: true
# The 1st reg will be recognized as common register if it has "interrupts".
