ARM: dts: rockchip: add rk3288 dma controllers

A patch from »ARM: rockchip: add dma support« in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Tue, 29 Jul 2014 21:12:07 +0200

Commit-Message

Add both the bus and peripheral pl330 dma controllers present in rk3288 socs. The first dma controller can change between secure and non-secure mode. Both instances are added but the non-secure variant is left disabled by default, as on the majority of boards the bootloader leaves it in secure mode. Signed-off-by: Heiko Stuebner <heiko@...>
