+RTL8723BS/RTL8723CS Bluetooth
|
||
|
|
+---------------------
|
||
|
|
+
|
||
|
|
+RTL8723CS/RTL8723CS is WiFi + BT chip. WiFi part is connected over SDIO, while
|
||
|
|
+BT is connected over serial. It speaks H5 protocol with few extra commands
|
||
|
|
+to upload firmware and change module speed.
|
||
|
|
+
|
||
|
|
+Required properties:
|
||
|
|
+
|
||
|
|
+ - compatible: should be one of the following:
|
||
|
|
+ * "realtek,rtl8723bs-bt"
|
||
|
|
+ * "realtek,rtl8723cs-bt"
|
||
|
|
+Optional properties:
|
||
|
|
+
|
||
|
|
+ - device-wake-gpios: GPIO specifier, used to wakeup the BT module (active high)
|
||
|
|
+ - enable-gpios: GPIO specifier, used to enable the BT module (active high)
|
||
|
|
+ - host-wake-gpios: GPIO specifier, used to wakeup the host processor (active high)
|
||
|
|
+ - firmware-postfix: firmware postfix to be used for firmware config
|
||
|
|
+ - reset-gpios: GPIO specifier, used to reset the BT module (active high)
|
||
|
|
+
|
||
|
|
+Example:
|
||
|
|
+
|
||
|
|
+&uart1 {
|
||
|
|
+ pinctrl-names = "default";
|
||
|
|
+ pinctrl-0 = <&uart1_pins>, <&uart1_rts_cts_pins>;
|
||
|
|
+ status = "okay";
|
||
|
|
+
|
||
|
|
+ bluetooth {
|
||
|
|
+ compatible = "realtek,rtl8723bs-bt";
|
||
|
|
+ reset-gpios = <&r_pio 0 4 GPIO_ACTIVE_LOW>; /* PL4 */
|
||
|
|
+ device-wake-gpios = <&r_pio 0 5 GPIO_ACTIVE_HIGH>; /* PL5 */
|
||
|
|
+ host-wakeup-gpios = <&r_pio 0 6 GPIO_ACTIVE_HIGH>; /* PL6 */
|
||
|
|
+ firmware-postfix="pine64";
|
||
|
|
+ };
|
||
|
|
+};
