The driver does register thermal zones. Since #thermal-sensor-cells is
mandatory for using it, I would think that the property is needed.

However, not all chips supported by the driver (and this bindings file)
have more than one channel, so I suspect that the value range might
need to be "enum: [0, 1]".
