Hi all i'm using a pwm output for control backlight of my screen. I need to have 2 PWM and i saw  that mx53 has two pwm output.

 

In mx53_loco.c i have:

 

MX53_PAD_GPIO_1__PWM2_PWMO,

 

static struct platform_pwm_backlight_data mxc_pwm_backlight_data = {
.pwm_id = 1,
.max_brightness = 255,
.dft_brightness = 128,
.pwm_period_ns = 50000,
};

 

mxc_register_device(&mxc_pwm2_device, NULL);
mxc_register_device(&mxc_pwm1_backlight_device, &mxc_pwm_backlight_data);

 

and i have a pwm output and it work correctly..

 

how can I to have another pwm output?

 

thanks
