The common DT property can be used to limit the available channels but ath9k has to manually call wiphy_read_of_freq_limits(). Signed-off-by: Christian Lamparter <chunkeey@xxxxxxxxx> --- 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. --- drivers/net/wireless/ath/ath9k/init.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/net/wireless/ath/ath9k/init.c b/drivers/net/wireless/ath/ath9k/init.c index 1568730fc01e..0344d6f27275 100644 --- a/drivers/net/wireless/ath/ath9k/init.c +++ b/drivers/net/wireless/ath/ath9k/init.c @@ -1094,6 +1094,8 @@ int ath9k_init_device(u16 devid, struct ath_softc *sc, ARRAY_SIZE(ath9k_tpt_blink)); #endif + wiphy_read_of_freq_limits(hw->wiphy); + /* Register with mac80211 */ error = ieee80211_register_hw(hw); if (error) -- 2.33.0
