The +Bluetooth part is a BCM20710 IC connected to UART2 in the A20 +SoC. The IC also takes a 32.768 KHz low power clock input, a power +enable signal and a wake signal via GPIO. + +The Bluetooth module supports out-of-band interrupt signaling via +GPIO, but this is not supported in this patch. +--- + arch/arm/boot/dts/sun7i-a20-cubietruck.dts | 36 ++++++++++++++++++++++++++++++ + 1 file changed, 36 insertions(+) + +--- a/arch/arm/boot/dts/sun7i-a20-cubietruck.dts ++++ b/arch/arm/boot/dts/sun7i-a20-cubietruck.dts +@@ -88,6 +88,20 @@ + interrupts = <10 8>; /* PH10 / EINT10 */ + interrupt-names = "host-wake"; + }; ++ ++ bt_pwr_pin: bt_pwr_pin@0 { ++ allwinner,pins = "PH18"; ++ allwinner,function = "gpio_out"; ++ allwinner,drive = <0>; ++ allwinner,pull = <0>; ++ }; ++ ++ bt_wake_pin: bt_wake_pin@0 { ++ allwinner,pins = "PH24"; ++ allwinner,function = "gpio_out"; ++ allwinner,drive = <0>; ++ allwinner,pull = <0>; ++ }; + }; + + usbphy: phy@01c13400 { +@@ -171,6 +185,12 @@ + status = "okay"; + }; + ++ uart2: serial@01c28800 { ++ pinctrl-names = "default"; ++ pinctrl-0 = <&uart2_pins_a>; ++ status = "okay"; ++ }; ++ + i2c0: i2c@01c2ac00 { + pinctrl-names = "default"; + pinctrl-0 = <&i2c0_pins_a>; +@@ -264,6 +284,22 @@ + enable-active-high; + gpio = <&pio 7 9 GPIO_ACTIVE_HIGH>; + }; ++ ++ rfkill-switches { ++ compatible = "simple-bus"; ++ pinctrl-names = "default"; ++ ++ rfkill_bt { ++ compatible = "rfkill-gpio"; ++ pinctrl-0 = <&bt_pwr_pin>, <&clk_out_a_pins_a>; ++ rfkill-name = "bt"; ++ rfkill-type = <2>; ++ bt_shutdown-gpios = <0>, <&pio 7 18 0>; /* PH18 */ ++ bt_reset-gpios = <&pio 7 24 0>; /* PH24 */ ++ clocks = <&clk_out_a>; ++ clock-frequency = <32768>; ++ }; ++ }; + }; + + #include "axp209.dtsi" |
