GPIO out configuration.

[Prajwal Upadhya]

Hi,
We are trying to set the GPIO135 available on the J3 expansion
header. We have deployed the android ice cream sandwich on the panda
board.

For this we have added the line "OMAP4_MUX(MCSPI1_SOMI,
OMAP_MUX_MODE3 | OMAP_PIN_OUTPUT)" in the struct omap_board_mux
board_mux[] of board-omap4panda.c.

This struct contains all the pin mux configurations. This change does
not seem to let us control the status (High/Low) of the pin. We were
wondering if anybody could point out the extra changes (if any) that
need to be done in order to configure the pin as an output pin.
