Subject: [PATCH v2 01/15] arm64: dts: mediatek: mt7981b: Configure UART0 pinmux
Date: Sat, 01 Nov 2025 14:32:46 +0100 [thread overview]
Message-ID: <20251101-openwrt-one-network-v2-1-2a162b9eea91@collabora.com> (raw)
In-Reply-To: <20251101-openwrt-one-network-v2-0-2a162b9eea91@collabora.com>
Add explicit pinctrl configuration for UART0
Signed-off-by: Sjoerd Simons <sjoerd@collabora.com>
---
V1 -> V2: Move pinctrl to the soc dtsi as it's the only available
pinmux for the uart. And very rare for the pins to be used for
anything else.
