Correct, 0x10 according to the DTS.

New debug session - I am not trusting the rate limiter anymore, but wrote my own
(printing every 100th read in the switch driver).
PLUS: Code to see which mdiobus_scan functions are actually called

Summary: Still 4 calls to mdio_bus_scan_c22, but also *2* calls to mdio_bus_scan_c45, approx. 190*100 reads by the switch driver
So, the two calls to mdio_bus_scan_c45 are *new* on the Omnia with the "bad" commit, and seem to cause quite some extra traffic (almost factor 10).
Regards, Klaus
