Subject: [PATCH 12/14] ARM: dts: qs600: add pwrseq support to WLAN
Date: Fri, 18 Sep 2015 13:32:05 +0100 [thread overview]
Message-ID: <1442579525-20440-1-git-send-email-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <1442579371-19822-1-git-send-email-srinivas.kandagatla@linaro.org>
Add pwrseq support to sdcc4 which would enable a proper reset of WLAN
without ugly hacks in the board support file.
Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
