Signed-off-by: Paul Elder --- Since the THP7312 supports multiple sensors, thine,rx-data-lanes alone might not be enough. I was consdering using sensor nodes like what the AP1302 does [1]. This way we can also move the power supplies that only concern the sensor in there as well. I was wondering what to do about the model name, though, as the thp7312 completely isolates that from the rest of the system. I'm planning to add sensor nodes in somehow in a v2.
