Actually, I believe that this is not correct (sorry I don't have the
Ralink driver at hand at the moment, nor the rt2x00 tree).
AFAIK the RF3052 needs the same initialization as for RF3020, RF3021,
RF3022, etc extended with the correct values for
5GHz band.
So, NAK for this patch.
Also, please keep in mind that for proper RT3572 support more needs to
be done, also in the register, BPP, and RFCSR initializations.
