1* MARVELL MMP DMA controller
2
3Marvell Peripheral DMA Controller
4Used platfroms: pxa688, pxa910, pxa3xx, etc
5
6Required properties:
7- compatible: Should be "marvell,pdma-1.0"
8- reg: Should contain DMA registers location and length.
9- interrupts: Either contain all of the per-channel DMA interrupts
10		or one irq for pdma device
11- #dma-channels: Number of DMA channels supported by the controller.
12
13"marvell,pdma-1.0"
14Used platfroms: pxa25x, pxa27x, pxa3xx, pxa93x, pxa168, pxa910, pxa688.
15
16Examples:
17
18/*
19 * Each channel has specific irq
20 * ICU parse out irq channel from ICU register,
21 * while DMA controller may not able to distinguish the irq channel
22 * Using this method, interrupt-parent is required as demuxer
23 * For example, pxa688 icu register 0x128, bit 0~15 is PDMA channel irq,
24 * 18~21 is ADMA irq
