21 | * ar9003_hw_set_channel - set channel on single-chip device | |
22 | * @ah: atheros hardware structure | |

24 | * | |
25 | * This is the function to change channel on single-chip devices, that is | |
26 | * all devices after ar9280. | |
27 | * | |
28 | * This function takes the channel value in MHz and sets | |
29 | * hardware channel value. Assumes writes have been enabled to analog bus. | |
30 | * | |
31 | * Actual Expression, | |
32 | * | |
33 | * For 2GHz channel, | |
34 | * Channel Frequency = (3/4) * freq_ref * (chansel[8:0] + chanfrac[16:0]/2^17) | |
35 | * (freq_ref = 40MHz) | |
36 | * | |
37 | * For 5GHz channel, | |
38 | * Channel Frequency = (3/2) * freq_ref * (chansel[8:0] + chanfrac[16:0]/2^10) | |
39 | * (freq_ref = 40MHz/(24>>amodeRefSel)) | |
40 | * | |
41 | * For 5GHz channels which are 5MHz spaced, | |
42 | * Channel Frequency = (3/2) * freq_ref * (chansel[8:0] + chanfrac[16:0]/2^17) | |
43 | * (freq_ref = 40MHz) | |
