- * 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
