Subject: [PATCH v1 4/4] riscv: dts: sifive unmatched: Add PWM controlled LEDs
Date: Tue, 5 Jul 2022 23:01:43 +0200 [thread overview]
Message-ID: <20220705210143.315151-5-emil.renner.berthing@canonical.com> (raw)
In-Reply-To: <20220705210143.315151-1-emil.renner.berthing@canonical.com>
This adds the two PWM controlled LEDs to the HiFive Unmatched device
tree. D12 is just a regular green diode, but D2 is an RGB diode with 3
PWM inputs controlling the three different colours.
