|
+* Freescale 83xx DMA Controller
|
|
|
+
|
|
|
+Freescale PowerPC 83xx have on chip general purpose DMA controllers.
|
|
|
+
|
|
|
+Required properties:
|
|
|
+
|
|
|
+- compatible : compatible list, contains 2 entries, first is
|
|
|
+ "fsl,CHIP-dma", where CHIP is the processor
|
|
|
+ (mpc8349, mpc8360, etc.) and the second is
|
|
|
+ "fsl,elo-dma"
|
|
|
+- reg : <registers mapping for DMA general status reg>
|
|
|
+- ranges : Should be defined as specified in 1) to describe the
|
|
|
+ DMA controller channels.
|
|
|
+- cell-index : controller index. 0 for controller @ 0x8100
|
|
|
+- interrupts : <interrupt mapping for DMA IRQ>
|
|
|
+- interrupt-parent : optional, if needed for interrupt mapping
|
|
|
+
|
|
|
+
|
|
|
+- DMA channel nodes:
|
|
|
+ - compatible : compatible list, contains 2 entries, first is
|
|
|
+ "fsl,CHIP-dma-channel", where CHIP is the processor
|
|
|
+ (mpc8349, mpc8350, etc.) and the second is
|
|
|
+ "fsl,elo-dma-channel"
|
|
|
+ - reg : <registers mapping for channel>
|
|
|
+ - cell-index : dma channel index starts at 0.
|
|
|
+
|
|
|
+Optional properties:
|
|
|
+ - interrupts : <interrupt mapping for DMA channel IRQ>
|
|
|
+ (on 83xx this is expected to be identical to
|
|
|
+ the interrupts property of the parent node)
|
|
|
+ - interrupt-parent : optional, if needed for interrupt mapping
|
|
|
+
|

|
