From 0f83ff69735651cc7a3d150466a5257ff829b62b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Tue, 17 Jan 2017 23:35:50 +0100 Subject: [PATCH] brcmfmac: use wiphy_read_of_freq_limits to respect limits from DT MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This new helper reads extra frequency limits specified in DT and disables unavailable chanels. This is useful for devices (like home routers) with chipsets limited e.g. by board design. In order to respect info read from DT we simply need to check for IEEE80211_CHAN_DISABLED bit when constructing channel info.
