Subject: [PATCH v2 2/4] arm64: dts: amlogic: meson-s4-s905y4-khadas-vim1s: enable bluetooth
Date: Sat, 28 Feb 2026 14:37:48 +0800	[thread overview]
Message-ID: <20260228063750.701887-3-nick@khadas.com> (raw)
In-Reply-To: <20260228063750.701887-1-nick@khadas.com>

The Khadas VIM1S board uses the Ampak AP6256 Wi-Fi/Bluetooth module.
The Bluetooth controller is connected via UART_A and requires the
external 32k clock (LPO).

Enable the UART_A node and add the bluetooth child node to support it.
