Subject: [PATCH] brcmfmac: use wiphy_read_of_freq_limits to respect limits
|
|
from DT

MIME-Version: 1.0

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.
