How fast is OMAP GPIO latching?

with the following code I am getting 2.4MHz-2.5MHz PWM pulse on the GPIO, for each interval. Is that the fastest? Anyway I can configure it to be faster to 50MHz?

I am using omap3430. This pieces of code is running on linux kernel.

while(!kthread_should_stop())
    {
        //printk( "my thread CurrTime: (%li)\n", (ktime_t)ktime_get());
        //gpio_set_value( GPIO_130_CLK, !gpio_get_value(GPIO_130_CLK) );
    
        set_current_state(TASK_RUNNING);

        for(i = 0; i <= 960; i++)
        {
            gpio_set_value( GPIO_130_CLK,HIGH);
            gpio_set_value( GPIO_130_CLK,LOW);
        }
        gpio_set_value( GPIO_130_CLK, LOW );

        set_current_state(TASK_INTERRUPTIBLE);

        //if(!kthread_should_stop())
        //schedule();

        schedule_timeout(1L);
        //schedule_hrtimeout();

        set_current_state(TASK_RUNNING);
        
    }
    __set_current_state(TASK_RUNNING);
