# This is the description of the GPIO lines used in this boot script:
#
# GPIO #105 is GPIO3_B1, or RK3399 ball C27, which controls the vibrator motor
# GPIO #154 is GPIO4_D2, or RK3399 ball AH3, which controls the red part of the multicolor LED
# GPIO #157 is GPIO4_D5, or RK3399 ball AJ3, which controls the green part of the multicolor LED
# GPIO #158 is GPIO4_D6, or RK3399 ball AG4, which controls the blue part of the multicolor LED
