From: Rafał Miłecki <rafal@xxxxxxxxxx> There are some devices (e.g. Netgear R8000 home router) with one chipset model used for different radios, some of them limited to subbands. NVRAM entries don't contain any extra info on such limitations and firmware reports full list of channels to us. We need to store extra limitation info on DT to support such devices properly. Signed-off-by: Rafał Miłecki <rafal@xxxxxxxxxx> --- This patch should probably go through wireless-driver-next, I'm sending it just as a proof of concept. It was succesfully tested on SmartRG SR400ac with BCM43602. --- drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c index ccae3bb..dab4082 100644 --- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c +++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c @@ -6825,6 +6825,7 @@ struct brcmf_cfg80211_info *brcmf_cfg80211_attach(struct brcmf_pub *drvr, goto priv_out; brcmf_dbg(INFO, "Registering custom regulatory\n"); + wiphy_read_of_freq_limits(wiphy); wiphy->reg_notifier = brcmf_cfg80211_reg_notifier; wiphy->regulatory_flags |= REGULATORY_CUSTOM_REG; wiphy_apply_custom_regulatory(wiphy, &brcmf_regdom); -- 2.10.1
