Need support SPI driver/document to support slave

[ramgopikrishna]

Hi,

I have been trying to make changes in spi-atmel in order to support slave, But there was some issues,
when doing that, If anybody done this before please share it, else at least please share document at-least how it can be done. Please do the needful.

Note: Using SAM9G25, 3.10 kernel, To support slave back ported spi framework from recent kernel. Issue facing when I am changing in spi-atmel.c.

Thanks,
Gopi Krishna
