Subject: [PATCH 4/5] arm64: dts: allwinner: a523: Add UART1 pins
Date: Fri, 20 Jun 2025 01:30:06 +0800	[thread overview]
Message-ID: <20250619173007.3367034-5-wens@kernel.org> (raw)
In-Reply-To: <20250619173007.3367034-1-wens@kernel.org>

From: Chen-Yu Tsai <wens@csie.org>

UART1 is normally used to connect to the Bluetooth side of a Broadcom
WiFi+BT combo chip. The connection uses 4 pins.

Add pinmux nodes for UART1, one for the RX/TX pins, and one for the
RTS/CTS pins.

Signed-off-by: Chen-Yu Tsai <wens@csie.org>
