Qualcomm Bluetooth Chips

This documents the binding structure and common properties for serial
attached Qualcomm devices.

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”

Optional properties:

• enable-gpios: gpio specifier used to enable chip
• clocks: clock provided to the controller (SUSCLK_32KHZ)

Example:

serial@7570000 {
label = “BT-UART”;
status = “okay”;

bluetooth {
    compatible = "qcom,qca6174-bt";

    enable-gpios = <&pm8994_gpios 19 GPIO_ACTIVE_HIGH>;
    clocks = <&divclk4>;
};

};
