Subject: [PATCH 0/4] patch serie for dw_spi driver
Date: Fri, 18 Mar 2011 15:50:52 +0800 [thread overview]
Message-ID: <1300434656-16870-1-git-send-email-feng.tang@intel.com> (raw)
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.
The patch serie is generated against 2.6.38 kernel.
Pls help to review, thanks!
