This removes the active-low properties of the PWM-controlled LEDs in
the HiFive Unmatched device tree.

Otherwise looks fine to me. Best regards Uwe -- Pengutronix e.K. | Uwe Kleine-König | Industrial Linux Solutions | https://www.pengutronix.de/ |

What did Vincent contribute to this patch? Are you missing a
co-developed-by tag, perhaps?

I expect this to go via the pwm tree since this is going to "break" (in
the loosest possible sense) existing systems if merged separately.
Cheers,
Conor.

Yes, Vincent was the first person to find the PWM driver problem, and
Zong Li helped me with the relevant review internally.
so in the next version, I will add the correct tags for these two developers.
Thank you again for your time.
