Subject: [PATCH v3] arm64: dts: meson-gxbb: nanopi-k2: Enable Bluetooth
Date: Mon, 12 Jul 2021 21:59:19 +0800 [thread overview]
Message-ID: <20210712135919.32059-1-wens@kernel.org> (raw)
From: Chen-Yu Tsai <wens@csie.org>
The NanoPi K2 has a AP6212 WiFi+BT combo module. The WiFi portion is
already enabled. The BT part is connected via UART and I2S.
Enable the UART and add a device node describing the Bluetooth portion
of the module.
