+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>;
+ };
+};

+Command DB
+---------
+
+Command DB is a database that provides a mapping between resource key and the
+resource address for a system resource managed by a remote processor. The data
+is stored in a shared memory region and is loaded by the remote processor.
+
+Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for
+controlling shared resources. Depending on the board configuration the shared
+resource properties may change. These properties are dynamically probed by the
+remote processor and made available in the shared memory.
+
+The bindings for Command DB is specified in the reserved-memory section in
+devicetree. The devicetree representation of the command DB driver should be:
+
+Properties:
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: Should be "qcom,cmd-db"
+
+- reg:
+ Usage: required
+ Value type: <prop encoded array>
+ Definition: The register address that points to the actual location of
+ the Command DB in memory.
+
+Example:
+
+ reserved-memory {
+ [...]
+ reserved-memory@85fe0000 {
+ reg = <0x0 0x85fe0000 0x0 0x20000>;
+ compatible = "qcom,cmd-db";
+ no-map;

+Qualcomm Technologies, Inc. GENI Serial Engine QUP Wrapper Controller
+
+Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) wrapper
+is a programmable module for supporting a wide range of serial interfaces
+like UART, SPI, I2C, I3C, etc. A single QUP module can provide upto 8 Serial
+Interfaces, using its internal Serial Engines. The GENI Serial Engine QUP
+Wrapper controller is modeled as a node with zero or more child nodes each
+representing a serial engine.
+
+Required properties:
+- compatible: Must be "qcom,geni-se-qup".
+- reg: Must contain QUP register address and length.
+- clock-names: Must contain "m-ahb" and "s-ahb".
+- clocks: AHB clocks needed by the device.
+
+Required properties if child node exists:
+- #address-cells: Must be <1> for Serial Engine Address
+- #size-cells: Must be <1> for Serial Engine Address Size
+- ranges: Must be present
+
+Properties for children:
+
+A GENI based QUP wrapper controller node can contain 0 or more child nodes
+representing serial devices. These serial devices can be a QCOM UART, I2C
+controller, SPI controller, or some combination of aforementioned devices.
+Please refer below the child node definitions for the supported serial
+interface protocols.
+
+Qualcomm Technologies Inc. GENI Serial Engine based I2C Controller
+
+Required properties:
+- compatible: Must be "qcom,geni-i2c".
+- reg: Must contain QUP register address and length.
+- interrupts: Must contain I2C interrupt.
+- clock-names: Must contain "se".
+- clocks: Serial engine core clock needed by the device.
+- #address-cells: Must be <1> for I2C device address.
+- #size-cells: Must be <0> as I2C addresses have no size component.
+
+Optional property:
+- clock-frequency: Desired I2C bus clock frequency in Hz.
+ When missing default to 400000Hz.
+
+Child nodes should conform to I2C bus binding as described in i2c.txt.
+
+Qualcomm Technologies Inc. GENI Serial Engine based UART Controller
+
+Required properties:
+- compatible: Must be "qcom,geni-debug-uart".
+- reg: Must contain UART register location and length.
+- interrupts: Must contain UART core interrupts.
+- clock-names: Must contain "se".
+- clocks: Serial engine core clock needed by the device.
+
+Qualcomm Technologies Inc. GENI Serial Engine based SPI Controller
+
+Required properties:
+- compatible: Must contain "qcom,geni-spi".
+- reg: Must contain SPI register location and length.
+- interrupts: Must contain SPI controller interrupts.
+- clock-names: Must contain "se".
+- clocks: Serial engine core clock needed by the device.
+- spi-max-frequency: Specifies maximum SPI clock frequency, units - Hz.
+- #address-cells: Must be <1> to define a chip select address on
+ the SPI bus.
+- #size-cells: Must be <0>.
+
+SPI slave nodes must be children of the SPI master node and conform to SPI bus
+binding as described in Documentation/devicetree/bindings/spi/spi-bus.txt.
