[PATCH 0/2] Bluetooth for the RTL8852BS on BPI-F3

[Frédéric Mahé]

The BPI-F3 (SpacemiT K1) carries an RTL8852BS Wi-Fi + Bluetooth module.
Wi-Fi (SDIO) has no upstream driver, but Bluetooth on UART works with
the existing hci_h5/btrtl code and linux-firmware's rtl8852bs files.

Patch 1 documents the compatible, with rtl8822cs-bt as fallback, so no
driver change is needed. Patch 2 enables it on the BPI-F3.

GPIO usage was tested one line at a time: GPIO 63 is the power/enable
line and GPIO 64 the device wake line. The vendor DT also drives
GPIO 65 and GPIO 67; Bluetooth works without them (and RSSI is the
same with GPIO 67 high or low), so they are left out.
