You're so close!

Your subject line should be "[PATCH] ARM: Kirkwood: Iomega ix2-200 DT
support"

Also, please add a short description of the device and a link to iomega
page describing it to the commit message (should start on the third line
of the commit message, above the Signed-off-by:).

Please remove 'coherent_pool=1M' that's a diagnosis tool, we still need
to get to the bottom of what that fixed.

Did Fabio's patch fix gpio-keys?  If so, please list that as a
dependency below the '---', ie 3 lines below the Signed-off-by:.
Include the link he supplied with that comment.

This is the wrong place for the Signed-off-by:, please see my comments,
above.  If anyone tries to apply this patch it will fail because git or
patch will think the sob is a line of context.  There won't be a match,
so it will fail.

hth,

Jason.
