      1Synaptics RMI4 F01 Device Binding
      2
      3The Synaptics RMI4 core is able to support RMI4 devices using different
      4transports and different functions. This file describes the device tree
      5bindings for devices which contain Function 1. Complete documentation
      6for transports and other functions can be found in:
      7Documentation/devicetree/bindings/input/rmi4.
      8
      9Additional documentation for F01 can be found at:
     10http://www.synaptics.com/sites/default/files/511-000136-01-Rev-E-RMI4-Interfacing-Guide.pdf

     12Optional Properties:
     13- syna,nosleep-mode: If set the device will run at full power without sleeping.
     14			nosleep has 3 modes, 0 will not change the default
     15			setting, 1 will disable nosleep (allow sleeping),
     16			and 2 will enable nosleep (disabling sleep).
     17- syna,wakeup-threshold: Defines the amplitude of the disturbance to the
     18				background capacitance that will cause the
     19				device to wake from dozing.
     20- syna,doze-holdoff-ms: The delay to wait after the last finger lift and the
     21				first doze cycle.
     22- syna,doze-interval-ms: The time period that the device sleeps between finger
     23				activity.

     26Example of a RMI4 I2C device with F01:
     27	Example:
     28	&i2c1 {
     29		rmi4-i2c-dev@2c {
     30			compatible = "syna,rmi4-i2c";
     31
     32			...
     33
     34			rmi4-f01@1 {
     35				reg = <0x1>;
     36				syna,nosleep-mode = <1>;
     37			};
     38		};
     39	};
