how modified mx53_loco.c for to have "Dual PWM"

[enaud]

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

As far as I have seen, the 1st PWM signal is not connected on the loco board.

If you derived your own board from loco, you probably have to set mux in the right configuration, add mxc_register_device(&mxc_pwm1_device, NULL) and probably to attach a driver to this pwm, like the "pwm-backlight" used here for the pwm2.

It is just a guess.
