[v2 PATCH 00/14] atmel SPI controller with dmaengine and device tree support

[Wenyou Yang]

Hi All, 

This set of patches is to add dmaengine and device tree support for atmel spi.
The work is based on Jean-Christophe, Nicolas and Richard's work.
I tested it on at91sam9x5ek, at91sam9m10g45ek.

It is based on v3.7-rc8.

Changelog:
v2: 
   1./ Remove the patch :PATCH]mtd: m25p80: change the m25p80_read to reading page to page
	which purpose to fix the BUG: when run "flashcp /bin/busybox /dev/mtdX" in 
	the at91sam9g25ek with DMA mode, it arises a OOPS. 
	Now fix it in this patch:
	[PATHC] spi/atmel_spi: add dmaengine support changing to fix the [BUG].

   2./ Remove two patches:
   	which purpose to read dts property to select SPI IP version and DMA mode
	Now they will be gat from device tree different compatile.

   3./ Fix DMA: when enable both spi0 AND spi1, the spi0 doesn't work BUG.

   4./ Rebase v3.7-rc8.

Best Regards,
Wenyou Yang.
