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.
