16 * PWM backlight circuit on this PinePhone revision was changed since 1.0,
17 * and the lowest PWM duty cycle that doesn't lead to backlight being off
18 * is around 10%. Duty cycle for the lowest brightness level also varries
19 * quite a bit between individual boards, so the lowest value here was
20 * chosen as a safe default.
