0001 Synaptics RMI4 F01 Device Binding
0002
0003 The Synaptics RMI4 core is able to support RMI4 devices using different
0004 transports and different functions. This file describes the device tree
0005 bindings for devices which contain Function 1. Complete documentation
0006 for transports and other functions can be found in:
0007 Documentation/devicetree/bindings/input/rmi4.
0008
0009 Additional documentation for F01 can be found at:

0011
0012 Optional Properties:
0013 - syna,nosleep-mode: If set the device will run at full power without sleeping.
0014                         nosleep has 3 modes, 0 will not change the default
0015                         setting, 1 will disable nosleep (allow sleeping),
0016                         and 2 will enable nosleep (disabling sleep).
0017 - syna,wakeup-threshold: Defines the amplitude of the disturbance to the
0018                                 background capacitance that will cause the
0019                                 device to wake from dozing.
0020 - syna,doze-holdoff-ms: The delay to wait after the last finger lift and the
0021                                 first doze cycle.
0022 - syna,doze-interval-ms: The time period that the device sleeps between finger
0023                                 activity.

0026 Example of a RMI4 I2C device with F01:
0027         Example:
0028         &i2c1 {
0029                 rmi4-i2c-dev@2c {
0030                         compatible = "syna,rmi4-i2c";
0031
0032                         ...
0033
0034                         rmi4-f01@1 {
0035                                 reg = <0x1>;
0036                                 syna,nosleep-mode = <1>;
0037                         };
0038                 };
0039         };
