| 15 | * struct atmel_pwm_bl_platform_data | |
| 16 | * @pwm_channel: which PWM channel in the PWM module to use. | |
| 17 | * @pwm_frequency: PWM frequency to generate, the driver will try to be as | |
| 18 | * close as the prescaler allows. | |
| 19 | * @pwm_compare_max: value to use in the PWM channel compare register. | |
| 20 | * @pwm_duty_max: maximum duty cycle value, must be less than or equal to | |
| 21 | * pwm_compare_max. | |
| 22 | * @pwm_duty_min: minimum duty cycle value, must be less than pwm_duty_max. | |
| 23 | * @pwm_active_low: set to one if the low part of the PWM signal increases the | |
| 24 | * brightness of the backlight. | |
| 25 | * @gpio_on: GPIO line to control the backlight on/off, set to -1 if not used. | |
| 26 | * @on_active_low: set to one if the on/off signal is on when GPIO is low. | |
| 27 | * | |
| 28 | * This struct must be added to the platform device in the board code. It is | |
| 29 | * used by the atmel-pwm-bl driver to setup the GPIO to control on/off and the | |
| 30 | * PWM device. | |
