[PATCH 1/2] dt-bindings: net: bluetooth: realtek: Add RTL8852BS

[Frédéric Mahé]

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.
