Hmm looking at things, we really should not set status = "disabled"
for any of the internal devices. Setting "disabled" makes the kernel
completely ignore the device and we're better off from PM point of
view to probe and idle the device. The devices are there for sure, and
typically just the pins are not configured for them.

How about just remove the status = "disabled" from am33xx.dtsi
instead?

Regards,

Tony
