How to change trigger in BSP for LED device
 
Hi!
I have register in BSP's driver a LED
Code:

static struct gpio_led ic_leds[] = {
        {
                .name                  = "led1:green",
                .gpio                  = USER_LED,
                .default_trigger        = "heartbeat",
                .active_low            = 1,
        },
};

static struct gpio_led_platform_data ic_led_info = {
        .num_leds      = ARRAY_SIZE(ic_leds),
        .leds          = ic_leds,
};

static struct platform_device ic_leds_device = {
        .name  = "leds-gpio",
        .id    = -1,
        .dev    = {
                .platform_data = &ic_led_info,
        },
};

static void __init ic_add_device_leds(void)
{
        platform_device_register(&ic_leds_device);
}

How can I change the trigger in run time?

I know that it's possible with sysfs, but maybe exist another way?
