+Realtek bluetooth devices connected via a UART
+
+- compatible: should be "realtek,<name>-bluetooth"
+  except for "realtek,trl8761atv" - which only has a serial bluetooth connection
+       "realtek,rtl8723as-bluetooth"
+       "realtek,rtl8723bs-bluetooth"
+       "realtek,rtl8723ds-bluetooth"
+       "realtek,rtl8761atv"
+       "realtek,rtl8821as-bluetooth"
+       "realtek,rtl8821cs-bluetooth"
+       "realtek,rtl8822bs-bluetooth"
+- These device are bluetooth devices, that connect via a uart
+- all devices (except for rtl8761atv) are also wifi devices, this is connected
+  seperatly via sdio - and is not covered by this compatible node
+- ideally these will be referenced in a device tree serial node via serdev
+ http://events17.linuxfoundation.org/sites/events/files/slides/serdev-elce-2017-2.pdf
+
+Example:
+
+&uart0 {
+	status = "okay";
+       	pinctrl-0 = <&uart0_xfer>, <&uart0_cts>;
+       	bluetooth {
+               	  compatible = "realtek,rtl8723bs-bluetooth";
+       	};
+};
+
+this ensures that the bluetooth device is tied to the correct uart
