Subject: [PATCH v7 1/3] riscv: dts: sifive: unleashed/unmatched: Remove PWM controlled LED's active-low properties
Date: Tue, 23 Jan 2024 14:17:46 +0800

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].
