With "getting WIFI MAC from NVMEM" working on ath79 on 5.10, the next logical step I think is to utilize nvmem subsystem to also get the calibration data from there. This will tremendously speed up the wifi bring-up, since we no longer need the userspace helper for the simple devices that can just load them from there. included with this patch is a package/mac80211/refresh. Tested on: WNDR3700v2, TP-Link Archer C7v2 Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

Subject: ath9k: support DT ieee80211-freq-limit property to limit channels
 | 
						|
 | 
						|
The common DT property can be used to limit the available channels
 | 
						|
but ath9k has to manually call wiphy_read_of_freq_limits().
 | 
						|
 | 
						|
I would have put this into ath9k_of_init(). But it didn't work there.
 | 
						|
The reason is that in ath9k_of_init() the channels and bands are not yet
 | 
						|
registered in the wiphy struct. So there isn't any channel to flag as
 | 
						|
disabled.
