Serial attached Qualcomm devices shall be a child node of the host UART device the slave device is attached to. Required properties: - compatible: should contain one of the following: * "qcom,qca6174-bt" * "qcom,qca9377-bt" * "qcom,wcn3990-bt" * "qcom,wcn3991-bt" * "qcom,wcn3998-bt" * "qcom,qca6390-bt" Optional properties for compatible string qcom,qca6174-bt: - enable-gpios: gpio specifier used to enable chip - clocks: clock provided to the controller (SUSCLK_32KHZ) - firmware-name: specify the name of nvm firmware to load Optional properties for compatible string qcom,qca9377-bt: - max-speed: see Documentation/devicetree/bindings/serial/serial.yaml Required properties for compatible string qcom,wcn399x-bt: - vddio-supply: VDD_IO supply regulator handle. - vddxo-supply: VDD_XO supply regulator handle. - vddrf-supply: VDD_RF supply regulator handle. - vddch0-supply: VDD_CH0 supply regulator handle. Optional properties for compatible string qcom,wcn399x-bt: - max-speed: see Documentation/devicetree/bindings/serial/serial.yaml - firmware-name: specify the name of nvm firmware to load - clocks: clock provided to the controller Examples: serial@7570000 { label = "BT-UART"; status = "okay"; bluetooth { compatible = "qcom,qca6174-bt"; enable-gpios = <&pm8994_gpios 19 GPIO_ACTIVE_HIGH>; clocks = <&divclk4>; firmware-name = "nvm_00440302.bin"; }; }; serial@898000 { bluetooth { compatible = "qcom,wcn3990-bt"; vddio-supply = <&vreg_s4a_1p8>; vddxo-supply = <&vreg_l7a_1p8>; vddrf-supply = <&vreg_l17a_1p3>; vddch0-supply = <&vreg_l25a_3p3>; max-speed = <3200000>; firmware-name = "crnv21.bin"; clocks = <&rpmhcc RPMH_RF_CLK2>; }; }; |
