* ST-Microelectronics FingerTip touchscreen controller
|
|
|
|
The ST-Microelectronics FingerTip device provides a basic touchscreen
|
|
functionality. Along with it the user can enable the touchkey which can work as
|
|
a basic HOME and BACK key for phones.
|
|
|
|
The driver supports also hovering as an absolute single touch event with x, y, z
|
|
coordinates.
|
|
|
|
Required properties:
|
|
- compatible : must be "st,stmfts" OR "st,fts" OR "st,fts2"
|
|
- reg : I2C slave address, (e.g. 0x49). Or 0 for SPI interface
|
|
- interrupts : interrupt specification
|
|
- avdd-supply : analogic power supply
|
|
- vdd-supply : power supply
|
|
- st,irq-gpio : interrupt gpio.
|
|
- st,irq-flags : irq trigger type config, , value should be:
|
|
1 - rising edge,
|
|
2 - falling edge,
|
|
4 - high level,
|
|
8 - low level.
|
|
- st,reset-gpio : reset gpio
|
|
- st,regulator_dvdd : dvdd regulator name
|
|
- st,regulator_avdd : avdd regulator name
|
|
|
|
Example:
|
|
|
|
&i2c_6 {
|
|
status = "ok";
|
|
st_fts@49 {
|
|
compatible = "st,fts";
|
|
reg = <0x49>;
|
|
|
|
interrupt-parent = <&tlmm>;
|
|
interrupts = <162 0x2008>;
|
|
vdd-supply = <&L4B>;
|
|
avdd-supply = <&L14B>;
|
|
st,irq-gpio = <&tlmm 162 0x2008>;
|
|
st,irq-flags = <8>;
|
|
st,reset-gpio = <&tlmm 161 0x00>;
|
|
st,regulator_dvdd = "vdd";
|
|
st,regulator_avdd = "avdd";
|
|
};
|
|
};
