Hello,

I use the ARM AT91SAM9G35 with the linux-3.10-at91 and I would like to change the basic frequency of the backlight. But in this version of Linux, I think the backlight driver is not managed via the device tree. How do I change the base frequency of the backlight PWM ?
In advance, thank you for your answer.

Best Regards,
