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.

9Additional documentation for F01 can be found at:

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.
