iMX51EVK backlight control

The Backlight control on the iMX51EVK is connected to pin DI1_D1_CS, the BSP just sets this up as a GPIO and turns the backlight on and off with this pin, however it seems it is possible to use this pin to provide some kind of PWM control to vary the backlight brightness. Has anyone doen this or can shed any light on it?
