/**
* DOC: Programming Atheros 802.11n analog front end radios
*
* AR5416 MAC based PCI devices and AR518 MAC based PCI-Express
* devices have either an external AR2133 analog front end radio for single
* band 2.4 GHz communication or an AR5133 analog front end radio for dual
* band 2.4 GHz / 5 GHz communication.
*
* All devices after the AR5416 and AR5418 family starting with the AR9280
* have their analog front radios, MAC/BB and host PCIe/USB interface embedded
* into a single-chip and require less programming.
*
* The following single-chips exist with a respective embedded radio:
*
* AR9280 - 11n dual-band 2x2 MIMO for PCIe
* AR9281 - 11n single-band 1x2 MIMO for PCIe
* AR9285 - 11n single-band 1x1 for PCIe
* AR9287 - 11n single-band 2x2 MIMO for PCIe
*
* AR9220 - 11n dual-band 2x2 MIMO for PCI
* AR9223 - 11n single-band 2x2 MIMO for PCI
*
* AR9287 - 11n single-band 1x1 MIMO for USB
