From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx> Add the Bluetooth node for RB5 as well as its dependencies in the form of the uart6 -> serial1 alias and the pin function for the Bluetooth enable GPIO. Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx> --- v1 -> v2: - squash the three device-tree patches into one - as we're only using a single pin for the BT enable GPIOs, there's no need for a separate named node - change the naming convention for regulators to follow the bindings arch/arm64/boot/dts/qcom/qrb5165-rb5.dts | 29 ++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/qrb5165-rb5.dts b/arch/arm64/boot/dts/qcom/qrb5165-rb5.dts index c8cd40a462a3..dfda57568dc5 100644 --- a/arch/arm64/boot/dts/qcom/qrb5165-rb5.dts +++ b/arch/arm64/boot/dts/qcom/qrb5165-rb5.dts @@ -23,6 +23,7 @@ / { aliases { serial0 = &uart12; + serial1 = &uart6; sdhc2 = &sdhc_2; }; @@ -1263,6 +1264,14 @@ &tlmm { "HST_WLAN_UART_TX", "HST_WLAN_UART_RX"; + bt_en_state: bt-default-state { + pins = "gpio21"; + function = "gpio"; + drive-strength = <16>; + output-low; + bias-pull-up; + }; + lt9611_irq_pin: lt9611-irq-state { pins = "gpio63"; function = "gpio"; @@ -1296,6 +1305,26 @@ sdc2_card_det_n: sd-card-det-n-state { }; }; +&uart6 { + status = "okay"; + + bluetooth { + compatible = "qcom,qca6390-bt"; + + pinctrl-names = "default"; + pinctrl-0 = <&bt_en_state>; + + enable-gpios = <&tlmm 21 GPIO_ACTIVE_HIGH>; + + vddio-supply = <&vreg_s4a_1p8>; + vddpmu-supply = <&vreg_s2f_0p95>; + vddaon-supply = <&vreg_s6a_0p95>; + vddrfa0p9-supply = <&vreg_s2f_0p95>; + vddrfa1p3-supply = <&vreg_s8c_1p3>; + vddrfa1p9-supply = <&vreg_s5a_1p9>; + }; +}; + &uart12 { status = "okay"; }; -- 2.40.1
