Subject: [PATCH v1 2/2] ARM: dts: hip04: add GPIO pieces
Date: Wed, 22 Oct 2014 19:56:00 +0800 [thread overview]
Message-ID: <1413978960-10717-3-git-send-email-wangzhou.bry@gmail.com> (raw)
In-Reply-To: <1413978960-10717-1-git-send-email-wangzhou.bry@gmail.com>
Hisilicon Soc hip04 has four GPIO controllers, each one has 32
GPIOs and can be configured to be an interrupt controller.The GPIO
controllers are compatible with the snps,dw-apb-gpio driver.
This patch add the corresponding device tree nodes.
