Ricardo, I modified this and the other dts patch to add new .dts files
for the board revisions with external pull on the SCL/SDA lines. Can you
verify that these are correct?
I verified the pinmux values to make sure that the OMAP internal pull is
not enabled in Pandaboard A4/4430 ES2.3+. It looks correct to me.
I also tested it on 4430 ES2.1 and 4430 ES2.3 SDPs and works fine.
BR,
Ricardo
