description: >
Minimum and maximum values produced by the axis.
For an ABS_X axis this will be the left-most and right-most
inclination of the joystick. If min > max, it is left to userspace to
treat the axis as inverted.
This property is interpreted as two signed 32 bit values.
abs-fuzz:

Amount of noise in the input value.
Omitting this property indicates the axis is precise.
abs-flat:

Axial "deadzone", or area around the center position, where the axis
is considered to be at rest.
Omitting this property indicates the axis always returns to exactly

Device tree bindings for Zinitx BT541 touchscreen controller
Required properties:
- compatible : Should be "zinitix,bt541"
- reg : I2C address of the chip. Should be 0x20
- interrupts : Interrupt to which the chip is connected
Optional properties:
- vdd-supply : Analog power supply regulator on VCCA pin
- vddo-supply : Digital power supply regulator on VDD pin
- zinitix,mode : Mode of reporting touch points. Some modes may not work
with a particular ts firmware for unknown reasons. Available
modes are 1 and 2. Mode 2 is the default and preferred.
The touchscreen-* properties are documented in touchscreen.txt in this
directory.
Example:
i2c@00000000 {
/* ... */
bt541@20 {
compatible = "zinitix,bt541";
reg = <0x20>;
interrupt-parent = <&msmgpio>;
interrupts = <13 IRQ_TYPE_EDGE_FALLING>;
pinctrl-names = "default";
pinctrl-0 = <&tsp_default>;
vdd-supply = <&reg_vdd_tsp>;
vddo-supply = <&pm8916_l6>;
touchscreen-size-x = <540>;
touchscreen-size-y = <960>;
zinitix,mode = <2>;

* Some 2-in-1s which use the soc_button_array driver have this ugly issue in
* their DSDT where the _LID method modifies the irq-type settings of the GPIOs
* used for the power and home buttons. The intend of this AML code is to
* disable these buttons when the lid is closed.
* The AML does this by directly poking the GPIO controllers registers. This is
* problematic because when re-enabling the irq, which happens whenever _LID
* gets called with the lid open (e.g. on boot and on resume), it sets the
* irq-type to IRQ_TYPE_LEVEL_LOW. Where as the gpio-keys driver programs the
* type to, and expects it to be, IRQ_TYPE_EDGE_BOTH.
* To work around this we don't set gpio_keys_button.gpio on these 2-in-1s,
* instead we get the irq for the GPIO ourselves, configure it as
* IRQ_TYPE_LEVEL_LOW (to match how the _LID AML code configures it) and pass
* the irq in gpio_keys_button.irq. Below is a list of affected devices.
