Some ARM64 boards (such as the Khadas VIM and many other Amlogic based devices) have one of the LEDs connected through a PWM controller. This allows dimming the LED. The ARM64 defconfig does not support the leds-pwm driver yet. Enabling that also means that we have to enable the default-on LED trigger. leds-gpio has a (trigger specific) "default-state" property which can be used to set the default state, while with leds-pwm this has to be configured using the default-on trigger.
