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.
