Subject: [PATCH 0/3 V3] Bluetooth: Add support for RTL8821CS

From: Chris Morgan <[email protected]>

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 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.

Now you added items which were never here... You have only one item, so
no need for items.
