Subject: [PATCH v3 02/13] arm64: dts: mediatek: mt7981b-openwrt-one: Enable software leds
Date: Wed, 05 Nov 2025 22:17:57 +0100 [thread overview]
Message-ID: <20251105-openwrt-one-network-v3-2-008e2cab38d1@collabora.com> (raw)
In-Reply-To: <20251105-openwrt-one-network-v3-0-008e2cab38d1@collabora.com>
The openwrt has 3 status leds at the front:
* red: Used as failsafe led by openwrt
* white: Used as boot led by openwrt
* green: Used as running/upgrade led by openwrt
On the back each RJ45 jack has the typical amber/green leds. For the WAN
jack this is hardware controlled by the phy, for LAN these are under
software control and enabled by this patch.
