[PATCH v2 5/6] wl12xx_sdio: declare support for NL80211_WOW_TRIGGER_ANYTHING trigger

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since wowlan requires the ability to stay awake while the host
is suspended, declare support for NL80211_WOW_TRIGGER_ANYTHING
if the MMC_PM_KEEP_POWER capability is being supported.
