Patch adds SDA and SCL pin numbers to the i2c platform data structure for Davinci DM355 and DM6446. This at present is used for i2c bus recovery. TODO: Add SDA and SCL pin number information to include all Davinci platforms such as dm355-leopard, dm365, dm646x, da8xx etc. Signed-off-by: Philby John <pjohn@in.mvista.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
