WiFi part 15 is connected over SDIO, while BT is connected over serial. It speaks 16 H5 protocol with few extra commands to upload firmware and change 17 module speed. 18 19properties: 20 compatible: 21 oneOf: 22 - enum: 23 - realtek,rtl8723bs-bt 24 - realtek,rtl8723cs-bt 25 - realtek,rtl8723ds-bt 26 - realtek,rtl8822cs-bt 27 - items: 28 - enum: 29 - realtek,rtl8821cs-bt 30 - const: realtek,rtl8723bs-bt 31 32 device-wake-gpios: 33 maxItems: 1 34 description: GPIO specifier, used to wakeup the BT module 35 36 enable-gpios: 37 maxItems: 1 38 description: GPIO specifier, used to enable the BT module 39 40 host-wake-gpios: 41 maxItems: 1 42 description: GPIO specifier, used to wakeup the host processor 43 44 max-speed: true 45 46required: 47 - compatible 48 49additionalProperties: false 50 51examples: 52 - | 53 #include <dt-bindings/gpio/gpio.h> 54 55 uart1 { 56 pinctrl-names = "default"; 57 pinctrl-0 = <&uart1_pins>, <&uart1_rts_cts_pins>; 58 uart-has-rtscts; 59 60 bluetooth { 61 compatible = "realtek,rtl8723bs-bt"; 62 device-wake-gpios = <&r_pio 0 5 GPIO_ACTIVE_HIGH>; /* PL5 */ 63 host-wake-gpios = <&r_pio 0 6 GPIO_ACTIVE_HIGH>; /* PL6 */ 64 }; 65 }; 66
