From 4c8dd973ef8e76f9fc622f0baab981769c89b601 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 9 Oct 2021 20:51:21 +0200 Subject: [PATCH] ath9k: OF: qca,disable-(2|5)ghz => ieee80211-freq-limit OpenWrt maintains two special out-of-tree DT properties: "qca,disable-5ghz" and "qca,disable-2ghz". These are implemented in a mac80211 ath9k patch "550-ath9k-disable-bands-via-dt.patch". With the things being what they are, now might be a good point to switch the devices to the generic and upstream "ieee80211-freq-limit" property. This property is much broader and works differently. Instead of disabling the drivers logic which would add the affected band and channels. It now disables all channels which are not within the specified frequency range.
