-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 100000Hz.
-
-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" or "qcom,geni-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
-node binding is described in
-Documentation/devicetree/bindings/spi/qcom,spi-geni-qcom.txt.

- pinctrl-1 = <&qup_1_i2c_5_sleep>;
- #address-cells = <1>;
- #size-cells = <0>;
- };
