- Subject: [PATCH] brcmfmac: use wiphy_read_of_freq_limits to respect limits
- from DT
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- 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.
