I have included all of the recommended changes in this version of the patch.
I also combined the patches into one patch to avoid bisecting issues. This
makes the diff on davinci_spi.c very large.
If people who are using this driver could test this version of the driver
and Ack it, I would appreciate it.
** NOTE **
This patch requires the EDMA patch at:
http://linux.davincidsp.com/pipermail/davinci-linux-open-source/2010-March/018022.html
which is queued waiting on another driver fix, for DMA mode to work correctly.

Quick update.
I tested this patch on DM355 and DM365 EVMs. On DM355 all the 3 modes (DMA,
Polled and Interrupt) worked fine. But in interrupt mode, on DM355, if I set
intr_level = 1, then kernel hangs during booting after printing
spi spi0.0: DaVinci SPI driver in Interrupt mode on the console.
On DM365 only DMA and Polled mode worked fine. In interrupt mode, whether I
set intr_level to ZERO or ONE, kernel booting hangs, similar to DM355.
I'll update the status of testing on OMAP-L1x EVMs later.
I am using the Linux kernel from [1] for testing.
