The HREFv60 variant of the MOP500 family of boards remove the external GPIO expander and route these pins back to some of the readily available internal GPIO pins instead. Based on a patch by Bibek Basu <bibek.basu@stericsson.com> for an internal kernel version. Cc: Bibek Basu <bibek.basu@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
