Hi Baruch and lists,
Here're various improvements / bug-fixing patches for DW I2C driver.
I'm working with v2.6.27-based kernel, but they must work fine with the
latest mainline kernel.
It's stil in RFC, and I'm working with it for some time. Any comments
or suggestions are highly appreciated. Then I'll respin and give it a
test, thanks.
Baruch, I'd say the base driver is in good shape enogh, so I'm having
a fun with modifing the driver. Thanks for the initial work.
P.S. ARM and MIPS lists are Cc:ed as I believe there must be potential
users of this driver.
