Thanks that works great for making things work eventually
with #pinctrl-cells = <2> :)

Since it sounds like you're modifying these with a script,
just leave out any nop comments while at it where the comment
is just the pad name already there in the new register
define. Some comments might need to be preserved, but my
guess is that they're mostly just the pad name.

And I suggest you split this change to a seprate patch
for each board so in case of trouble we can revert the
changes for a single board if needed.

Tony
