[PATCH v2 0/4] patch serie for dw_spi driver

[Feng Tang <feng.tang-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

Hi all,

Alek Du made some optimization for the dw_spi driver, the original driver
will wait for non-busy state after every work of read/write. With these
patches, driver will read/write as much as possible data from/to the HW
FIFO. The DMA mode transfer is not affected at all. There is also some
minor code cleanup.

Pls help to review, thanks!

v2 change:
	* fix a typo about bits_per_word checking 
	* re-generate the patches against v2.6.39-rc1

Thanks,
Feng
