Hi Rob,

thanks for the feedback, I am fixing up the patches with some

Why do you need to describe the drives in DT for IDE? They are
discoverable, right? And unlike SATA, the power to master and slave is
shared.

It is because of a related patch set by Guenter Roeck where we
add thermal zones to the thermal sensors found in the drives.

To associate these with a thermal zone as defined in device tree,
I need a handle on the drive.

See my mail to hwmon for an example:
