+Realtek Bluetooth devices connected via a UART.
+These devices typically also have a WI-FI connected via SDIO - the
+compatible described here is used just for referencing the Bluetooth.
+
+- compatible: should be "realtek,<name>-bt"
+ except for "realtek,trl8761atv" - which only has a serial Bluetooth connection
+ "realtek,rtl8723as-bt"
+ "realtek,rtl8723bs-bt"
+ "realtek,rtl8723ds-bt"
+ "realtek,rtl8761atv"
+ "realtek,rtl8821as-bt"
+ "realtek,rtl8821cs-bt"
+ "realtek,rtl8822bs-bt"
+
+Example:
+
+&uart0 {
+ status = "okay";
+ pinctrl-0 = <&uart0_xfer>, <&uart0_cts>;
+ bluetooth {
+ compatible = "realtek,rtl8723bs-bt";
+ uart_rts_gpios = <&gpio4 19 GPIO_ACTIVE_LOW>;
+ pinctrl-names = "default","rts_gpio";
+ pinctrl-0 = <&uart0_rts>;
+ pinctrl-1 = <&uart0_gpios>;
+ BT,reset_gpio = <&gpio4 29 GPIO_ACTIVE_HIGH>;
+ BT,wake_gpio = <&gpio4 26 GPIO_ACTIVE_HIGH>;
+ BT,wake_host_irq = <&gpio4 31 GPIO_ACTIVE_HIGH>;
+ };
+};
+
+this ensures that the Bluetooth device is tied to the correct uart.
