 * \brief Test for PWM driver (implementation)
 *
 * This is a simple test for PWM driver. This module
 * is target independent, so you can test all target that
 * BeRTOS support.
 * To use this test you should include a pwm_map.h header where
 * are defined the PWM channels for your target. Then you should add
 * or remove a test setting in pwm_test_cfg array, and edit a value for
 * your specific test.
 * Afther this, all is ready and you can test PWM driver.
 *
 * The test check first if all PWM channel starts, and then try
 * to change a PWM duty cicle for all channel.
 * The change of duty cycle is operate when a PWM channel is enable,
 * in this way you can see if a pwm signal is clean and work properly.
 * The duty value is change incrementaly, and when it arrive to 100% or 0%,
 * we reset the duty value and restart the test.
 * Further the duty test, we check also a PWM polarity, infact when we
 * reach a reset duty value, we invert a polary of PWM wavform.
 * So you can see if the hardware manage correctly this situation.
 *
 * Note: To be simple and target independently we not use a timer module,
 * and so the delay is do with a for cycle.
