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.

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 = <®_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.
