/* MEC172x EVB
 * BBLED controller 0 uses GPIO156/LED1 connected to JP71-11
 * BBLED controller 1 uses GPIO157/LED2 connected to JP71-13
 * BBLED controller 2 uses GPIO153/LED3 connected to JP71-5
 * BBLED controller 3 uses GPIO035/PWM8 connected to JP67-19
 * NOTE: Data sheet indicates BBLED3 uses GPIO035.
 * Schematic Rev A1p0 shows LED3 on GPIO226 (incorrect).
 * BBLED hardware divides input clock (32KHz or 48MHz) by (256 * (prescalar+1)
 * and implements duty cycle for blink mode as an 8-bit value where 0 is off and
 * 255 full on. BBLED PWM is 8-bit.
 * BBLED-PWM driver get cycles API reports 32KHz/256 or 48M/256.
 * Due to all the above we use 50 ms for DT PWM period.
