ARM: dts: add generic DMA device tree binding for mxs-dma
Add generic DMA device tree binding for mxs-dma. The changes include: * Add channel interrupts into DMA controller nodes * Add properties '#dma-cells' and 'dma-channels' for DMA controller nodes * And properties 'dmas' and 'dma-names' for DMA client nodes * Update mxs-dma device tree binding doc Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Reviewed-by: Arnd Bergmann <arnd@arndb.de>
