> Hi All,
>
> This set of patches is to add dmaengine and device tree support for atmel spi.
> The work is based on Nicolas and Richard's work.
> It is tested on at91sam9x5ek, at91sam9m10g45ek, at91sam9263ek and at91sam9g20ek.

Hi,
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).

> V3:
>         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.
>
> 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.
