'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

* HiDeep Finger and Stylus touchscreen controller
|
|
|
|
Required properties:
|
|
- compatible : must be "hideep,hideep-ts"
|
|
- reg : I2C slave address, (e.g. 0x6C).
|
|
- interrupts : Interrupt to which the chip is connected.
|
|
|
|
Optional properties:
|
|
- vdd-supply : It is the controller supply for controlling
|
|
main voltage(3.3V) through the regulator.
|
|
- vid-supply : It is the controller supply for controlling
|
|
IO voltage(1.8V) through the regulator.
|
|
- reset-gpios : Define for reset gpio pin.
|
|
It is to use for reset IC.
|
|
- touchscreen-size-x : X axis size of touchscreen
|
|
- touchscreen-size-y : Y axis size of touchscreen
|
|
- linux,keycodes : Specifies an array of numeric keycode values to
|
|
be used for reporting button presses. The array can
|
|
contain up to 3 entries.
|
|
|
|
Example:
|
|
|
|
#include "dt-bindings/input/input.h"
|
|
|
|

|
|
interrupts = <2 IRQ_TYPE_LEVEL_LOW>;
|
|
vdd-supply = <&ldo15_reg>";
