This initial device-tree provides the necessary configuration for basic BMC functionality such as host power control, serial console and KVM support, and POST code snooping.

It will *happen* to work as expected because ADC is the default mux state for the pins, but by not requesting the lines you're leaving the pins available for a conflicting request, which can be annoying to debug.
Ack, thanks -- will fix & resend.

Sure, I'll try to give that a shot and report back in the next day or two.
