ARM: dts: rockchip: add rk3188 dma controllers
From: Heiko Stuebner <heiko@...> Date: Tue, 29 Jul 2014 19:34:23 +0200
Commit-Message
Add both the cpu and peripheral pl330 dma controllers present in rk3188 socs. The first dma controller can change between secure and non-secure mode and is left by the bootloader in secure mode, which gets added here. Signed-off-by: Heiko Stuebner <heiko@...>
