Synaptics RMI4 I2C 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 using the I2C transport driver. Complete documentation for other transports and functions can be found in Documentation/devicetree/bindings/input/rmi4. Required Properties: - compatible: syna,rmi4-i2c - reg: I2C address - #address-cells: Set to 1 to indicate that the function child nodes consist of only on uint32 value. - #size-cells: Set to 0 to indicate that the function child nodes do not have a size property. Optional Properties: - interrupts: interrupt which the rmi device is connected to. See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt - syna,reset-delay-ms: The number of milliseconds to wait after resetting the device. - syna,startup-delay-ms: The number of milliseconds to wait after powering on the device. - vdd-supply: VDD power supply. See ../regulator/regulator.txt - vio-supply: VIO power supply See ../regulator/regulator.txt Function Parameters: Parameters specific to RMI functions are contained in child nodes of the rmi device node. Documentation for the parameters of each function can be found in: Documentation/devicetree/bindings/input/rmi4/rmi_f*.txt. Example: &i2c1 { rmi4-i2c-dev@2c { compatible = "syna,rmi4-i2c"; reg = <0x2c>; #address-cells = <1>; #size-cells = <0>; interrupt-parent = <&gpio>; interrupts = <4 2>; rmi4-f01@1 { reg = <0x1>; syna,nosleep-mode = <1>; }; rmi4-f11@11 { reg = <0x11>; touchscreen-inverted-y; syna,sensor-type = <2>; }; }; };
