    Subject[PATCH v3 11/12] davinci: add tnetv107x evm backlight device
    Date
    The tnetv107x evm board has a backlight device that is connected on one of the
    SSP ports. This patch adds the board definitions necessary to plug the
    backlight driver to the GPIO corresponding to this SSP pin.
