v6:
- Remove chip specific pinctrl conf
- Move gpio and clocks into optional props section
v5:
- Rename 'bt-disable-n' gpio as 'enable'
v4:
- Move bt-disable-n-gpios to required properties section
- Add clocks and pinctrl-0 as required properties
v3: no change
v2: no change

+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 controler (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>;
+ };
+};
