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";
|
||||||
|
};
|
||||||
|
};
