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.
It is based on v3.8-rc2.
Changelog:
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.
Best Regards,
Wenyou Yang.
