This patch series is to add support for the RTL8821CS Bluetooth
controller found on the RTL8821CS WiFi/Bluetooth combo chip.
This has been tested with firmware version 0x75b8f098 which has been
submitted by Realtek for inclusion in linux-firmware.
https://lore.kernel.org/linux-firmware/[email protected]/
Changes from V4:
- After extensive testing it was found that there are problems with
using the bluetooth that were not caught with the initial testing.
This can be mitigated by setting the "H5_INFO_WAKEUP_DISABLE" flag.
The easiest way to accomplish that is to change the fallback
compatible string to "realtek,rtl8723bs-bt". Updated the binding
documentation and binding to reflect this. No change to the driver
from V4 was necessary. Removed "reviewed-by" from documentation due
to this change.
Changes from V3:
- Corrected bindings so that all but the 8821 use enum, and 8821 uses
items.
Changes from V2:
- Corrected devicetree documentation to change compatible from const
back to enum.
- Removed "reviewed-by" from Alistair Francis as binding documentation
updated with changes.
Changes from V1:
- Switched to use a fallback string for the rtl8822cs so as to not add
an extra entry to the of_device_id table. The driver is capable of
selecting the correct firmware blob to load.
- Updated the messages to note a new version of the firmware was
tested and that Realtek has submitted this firmware upstream.
- Updated the devicetree node on the Anbernic RGxx3 series to use the
fallback string of realtek,rtl8822cs-bt.

RTL8821CS is a WiFi + Bluetooth combo chip from Realtek that provides
WiFi A/B/G/N/AC over an SDIO interface and Bluetooth 4.2 over a UART
interface.
Note that the firmware this was tested with was firmware version
0x75b8f098.
