Not talking about this in specific, but I will need to add DT bindings
for ATA master/slave, in order to add a temperature zone
for each drive (one sensor in each drive) in my in-progress
hwmon-over-SCSI-emulation-ATA-sensors such that:

ata-controller {
      ata-master {
      };
      ata-slave {
      };
};

I haven't looked closer at this topology yet, but we definatelt
need nodes for each physical connector out of an ATA
master, somehow, so they can act as a sensor/temperature
zone.
