You need a min/maxItems here as well. Otherwise, on the H6, you will
have a warning since you asked for an array of two items, bus and ahb,
while you only have a single one.

This must be checked using a conditional.

Something like:

if:
  properties:
    compatible:
      const: allwinner,sun8i-h3-ths

then:
  properties:
    "#thermal-sensor-cells":
      const: 0

else:
  properties:
    "#thermal-sensor-cells":
      const: 1

Same remark here, it won't compile
