[RFC PATCH v2 02/16] ARM: davinci: move private EDMA API to arm/common

[Matt Porter <mporter-l0cyMroinI0@public.gmane.org>]

Move mach-davinci/dma.c to common/edma.c so it can be used
by OMAP (specifically AM33xx) as well. This just moves the
private EDMA API but does not support OMAP.

-/*
- * This EDMA3 programming framework exposes two basic kinds of resource:
- *
- *  Channel	Triggers transfers, usually from a hardware event but
- *		also manually or by "chaining" from DMA completions.
- *		Each channel is coupled to a Parameter RAM (PaRAM) slot.
- *
- *  Slot	Each PaRAM slot holds a DMA transfer descriptor (PaRAM
- *		"set"), source and destination addresses, a link to a
- *		next PaRAM slot (if any), options for the transfer, and
- *		instructions for updating those addresses.  There are
- *		more than twice as many slots as event channels.
- *
- * Each PaRAM set describes a sequence of transfers, either for one large
- * buffer or for several discontiguous smaller buffers.  An EDMA transfer
- * is driven only from a channel, which performs the transfers specified
- * in its PaRAM slot until there are no more transfers.  When that last
- * transfer completes, the "link" field may be used to reload the channel's
- * PaRAM slot with a new transfer descriptor.
- *
- * The EDMA Channel Controller (CC) maps requests from channels into physical
- * Transfer Controller (TC) requests when the channel triggers (by hardware
- * or software events, or by chaining).  The two physical DMA channels provided
- * by the TCs are thus shared by many logical channels.
- *
- * DaVinci hardware also has a "QDMA" mechanism which is not currently
- * supported through this interface.  (DSP firmware uses it though.)

+/*
+ * This EDMA3 programming framework exposes two basic kinds of resource:
+ *
+ *  Channel	Triggers transfers, usually from a hardware event but
+ *		also manually or by "chaining" from DMA completions.
+ *		Each channel is coupled to a Parameter RAM (PaRAM) slot.
+ *
+ *  Slot	Each PaRAM slot holds a DMA transfer descriptor (PaRAM
+ *		"set"), source and destination addresses, a link to a
+ *		next PaRAM slot (if any), options for the transfer, and
+ *		instructions for updating those addresses.  There are
+ *		more than twice as many slots as event channels.
+ *
+ * Each PaRAM set describes a sequence of transfers, either for one large
+ * buffer or for several discontiguous smaller buffers.  An EDMA transfer
+ * is driven only from a channel, which performs the transfers specified
+ * in its PaRAM slot until there are no more transfers.  When that last
+ * transfer completes, the "link" field may be used to reload the channel's
+ * PaRAM slot with a new transfer descriptor.
+ *
+ * The EDMA Channel Controller (CC) maps requests from channels into physical
+ * Transfer Controller (TC) requests when the channel triggers (by hardware
+ * or software events, or by chaining).  The two physical DMA channels provided
+ * by the TCs are thus shared by many logical channels.
+ *
+ * DaVinci hardware also has a "QDMA" mechanism which is not currently
+ * supported through this interface.  (DSP firmware uses it though.)
