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
