[PATCH 00/23] work in progress: SPI controller w/DMA SAM9X5

[Richard Genoud]

Nicolas,
I said that I had some work done on sam9g35-ek, here is the spi part, based
on your and Jean-Christophe work.
You have to enable CONFIG_ARCH_AT91SAM9X5 to get it work.

The goal of this patchset is to share the work I've done, it's not ready
for upstream, but it may save some time.

It's based on 3.6-rc1 + Jean-Christophe's pinctrl patchset.

Best Regards,
Richard.
