From 03469e79fee9e8e908dae3bd1a80bcd9a66f2a88 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Mon, 11 Oct 2021 18:18:00 +0300 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.
