Could you recheck with your hardware guys which input clocks
this device really has. On earlier i.MX there are up to three
clocks this module needs. Sooner or later we want to use this driver on
the other i.MX aswell, and then we'll need support for the other clocks
here, no matter if they are software controllable on i.MX6 or not.
