Subject: [PATCH v2] arm64: dts: meson-gxbb: nanopi-k2: Enable Bluetooth
Date: Tue, 4 May 2021 12:16:59 +0800 [thread overview]
Message-ID: <20210504041659.22495-1-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.
Signed-off-by: Chen-Yu Tsai <wens@csie.org>

Changes since v1:
- added uart-has-rtscts property
- added alias for uart_A
Hi Neil, Martin,
I dropped your review-bys since I added the UART alias and I'm not sure
what the policy for those are.
