> Hi All,
> This set of patches is to add dmaengine and device tree support for atmel spi.

You should rebase it on rc4 because __devinit macros are gone in rc4.
(cf 54b956b903607f8f8878754dd4352da6a54a1da2 )
So the patches 05 and 06 will break compilation.
> 1./ Take Joe Perches's advance, rewrite atmel_spi_is_v2(struct atmel_spi *as)
> and atmel_spi_use_dma(struct atmel_spi *as),
> and remove atmel_spi_use_pdc(struct atmel_spi *as).
> 2./ Rebase on v3.8-rc3.
> 1./ Rebase on v3.8-rc2.
> 2./ Remove some Jean-Christophe's patches which has been
> applied on v3.8-rc2.
> 3./ Remove spi property "cs-gpios" from the SoC dtsi files
> to the board dts files to avoid some useless pin conflicts.
> 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,
