[PATCH 2/2] ARM: dts: hip04: add gpio pieces

Wed Apr 23 04:51:35 PDT 2014


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.
