     Synaptics RMI4 F01 Device Binding
     
     The Synaptics RMI4 core is able to support RMI4 devices using different
     transports and different functions. This file describes the device tree
     bindings for devices which contain Function 1. Complete documentation
     for transports and other functions can be found in:
     Documentation/devicetree/bindings/input/rmi4.
     
     Additional documentation for F01 can be found at:
    http://www.synaptics.com/sites/default/files/511-000136-01-Rev-E-RMI4-Interfacing-Guide.pdf
    
    Optional Properties:
    - syna,nosleep-mode: If set the device will run at full power without sleeping.
                            nosleep has 3 modes, 0 will not change the default
                            setting, 1 will disable nosleep (allow sleeping),
                            and 2 will enable nosleep (disabling sleep).
    - syna,wakeup-threshold: Defines the amplitude of the disturbance to the
                                    background capacitance that will cause the
                                    device to wake from dozing.
    - syna,doze-holdoff-ms: The delay to wait after the last finger lift and the
                                    first doze cycle.
    - syna,doze-interval-ms: The time period that the device sleeps between finger
                                    activity.
    
    
    Example of a RMI4 I2C device with F01:
            Example:
            &i2c1 {
                    rmi4-i2c-dev@2c {
                            compatible = "syna,rmi4-i2c";
    
                            ...
    
                            rmi4-f01@1 {
                                    reg = <0x1>;
                                    syna,nosleep-mode = <1>;
                            };
                    };
            };
