Johan Hedberg says:

====================
pull request: bluetooth-next 2018-05-18

Here's the first bluetooth-next pull request for the 4.18 kernel:

 - Refactoring of the btbcm driver
 - New USB IDs for QCA_ROME and LiteOn controllers
 - Buffer overflow fix if the controller sends invalid advertising data length
 - Various cleanups & fixes for Qualcomm controllers

Please let me know if there are any issues pulling. Thanks.

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>;

	};

};
