Recently I compiled firmware for ar9344 device , the board support 2.4g + 5g radios , the Soc ar9344 is working as 5g band radio and use Atheros driver as in the image attached , the radio 2.4g chipset is ar9382 , my question is it normal to have 2 different drivers as in the image for the 2 Atheros chipsets .
thanks
yup, the 11n radio would use a different kmod.
thanks , do you know which kmod for ar9382 , my firmware has ( kmod-ath, kmod-ath9k and kmod-ath9k-common ) .
wait, they're both N radios, or is one AC ?
The both are N radios
Your screenshot does not show any actual driver information. Just how the radio is registered with the driver. The 'generic' bit indicates the PCI ID is not known to the driver as a specific model.

Which (relevant) modules have you installed?
This is your PCI ID: 168c:abcd. What card is this? Is your 2,4 GHz radio working? Or not? That's unclear.
@frollic This is just a second radio supported by ath9k, nothing special. If the radio is working as intended the only thing missing is an entry in libiwinfo's devices.txt. There is no second driver in play; and I will amend the topic title to reflect what is actually at play here. This is a cosmetic 'issue' if the radio is working just fine.
This is what's in devices.txt from that vendor (if it is indeed a correct PCI ID):

Thanks , 2,4 GHz radio is working properly , also there is no problem with the performance of the device but this is first time I see this two different drivers for regular Atheros ath9k device.
best regards
I googled about id 168c:abcd and found this notice ( it means there is a problem recognizing the card )
No, there is no problem at all.
ar9382 is not mentioned in the devices.txt you provided
…and that doesn't matter at all, it doesn't have the slightest influence on functionality - as Borromini mentioned, this is merely a pretty label to appease the human in front of the device, without any purpose beyond that.
