Make sure you modify the DTS file since with this patch the period is
now passed through the conventional way.
Example:
pwmleds {
compatible = "pwm-leds";
heartbeat {
pwms = <&L45 0 100000 0>;
max-brightness = <255>;
linux,default-trigger = "heartbeat";
};
};
I have tested the heartbeat trigger on HiFive Unleashed board and it's
working with this PWM patch.
