[PATCH v2 1/2] riscv: dts: sifive: unleashed/unmatched: Remove PWM controlled LED's active-low properties

Nylon Chen posted 2 patches 3 years ago
There is a newer version of this series
[PATCH v2 1/2] riscv: dts: sifive: unleashed/unmatched: Remove PWM controlled LED's active-low properties
Posted by Nylon Chen 3 years ago 
This removes the active-low properties of the PWM-controlled LEDs in
the HiFive Unmatched device tree.

The reference is hifive-unleashed-a00.pdf[0] and hifive-unmatched-schematics-v3.pdf[1].

Ideally these would be:

so that they integrate nice with the git trailers mechanism.
If you resend, please update them to regular link tags.

I checked out the circuits last time around and agreed that they should
not be active-low.

I expect that both patches will go through the PWM tree together, so:
