Subject: [PATCH 1/2] dt-bindings: net: bluetooth: realtek: Add RTL8852BS
Date: Tue, 10 Nov 2026 08:46:06 +0100 [thread overview]
Message-ID: <20261110074607.363918-2-frederic.mahe@cirad.fr> (raw)
In-Reply-To: <20261110074607.363918-1-frederic.mahe@cirad.fr>
The RTL8852BS is a Wi-Fi 6 + Bluetooth 5.2 chip with Wi-Fi on SDIO
and Bluetooth on UART (H5). Its Bluetooth part works with the
RTL8822CS driver data, so use realtek,rtl8822cs-bt as fallback.
This patch was prepared with the help of an AI assistant (Claude),
which also ran the tests.
