Subject: [PATCH v2 1/2] riscv: dts: sifive: unleashed/unmatched: Remove PWM controlled LED's active-low properties
Date: Mon, 30 Jan 2023 17:32:28 +0800 [thread overview]
Message-ID: <20230130093229.27489-2-nylon.chen@sifive.com> (raw)
In-Reply-To: <20230130093229.27489-1-nylon.chen@sifive.com>
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].
