Subject: [PATCH edk2-platforms v4 3/6] Platform/HiKey960: enable virtual keyboard
Date: Mon, 14 May 2018 12:34:30 +0800 [thread overview]
Message-ID: <1526272473-25565-4-git-send-email-haojian.zhuang@linaro.org> (raw)
In-Reply-To: <1526272473-25565-1-git-send-email-haojian.zhuang@linaro.org>
Enable virtual keyboard on HiKey960 platform. It checks two
conditions, such as pattern in memory and GPIO pin setting.
