|  | * @pwm_compare_max: value to use in the PWM channel compare register. | 
|  | * @pwm_duty_max: maximum duty cycle value, must be less than or equal to | 
|  | *	pwm_compare_max. | 
|  | * @pwm_duty_min: minimum duty cycle value, must be less than pwm_duty_max. | 
|  | * @pwm_active_low: set to one if the low part of the PWM signal increases the |

|  | * @gpio_on: GPIO line to control the backlight on/off, set to -1 if not used. |
