From: maxx <[email protected]> This actually fixes region selection for BCM2048 FM receiver. To select the japanese FM-band an additional bit in FM_CTRL register needs to be set. This might not sound so important but it enables at least me to listen to some 'very interesting' radio transmission below normal FM-band.
