I am not aware of bindings required for l2switch as we are not working 
on the driver.
Earlier I thought of putting a place holder. but as you suggested to put 
bindings in documentation.
it will require proper discussion this may delay the base patch acceptance.
so It will be good if it is put by actual driver owner.

do we have any scripts which check for whitespace as checkpatch never 
give any warning/error.
it is a very silly mistake which I am doing continuously :(

yes. Ideally it should be.
but if i put a comment then I believe this patch will not be completed. 
it will think as a RFC.
as I believe putting of TODO is generally for RFC patches.

should I put comment without TODO?
