'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.

Texas Instruments Palmas family power button module
|
|
|
|
This module is part of the Palmas family of PMICs. For more details
|
|
about the whole chip see:
|
|
Documentation/devicetree/bindings/mfd/palmas.txt.
|
|
|
|
This module provides a simple power button event via an Interrupt.
|
|
|
|
Required properties:
|
|
- compatible: should be one of the following
|
|
- "ti,palmas-pwrbutton": For Palmas compatible power on button
|
|
- interrupts: Interrupt number of power button submodule on device.
|
|
|
|
Optional Properties:
|
|
|
|
- ti,palmas-long-press-seconds: Duration in seconds which the power
|
|
button should be kept pressed for Palmas to power off automatically.
|
|
NOTE: This depends on OTP support and POWERHOLD signal configuration
|
|
on platform. Valid values are 6, 8, 10 and 12.
|
|
- ti,palmas-pwron-debounce-milli-seconds: Duration in milliseconds
|
|
which the power button should be kept pressed for Palmas to register
|
|
a press for debouncing purposes. NOTE: This depends on specific
|
|
Palmas variation capability. Valid values are 15, 100, 500 and 1000.
|
|
|
|
Example:
|
|
|
|
&palmas {
|
|
palmas_pwr_button: pwrbutton {
|
|
compatible = "ti,palmas-pwrbutton";
|
|
interrupt-parent = <&tps659038>;
|
|
interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
|
|
ti,palmas-long-press-seconds = <12>;
|
|
ti,palmas-pwron-debounce-milli-seconds = <15>;
|
|
};
|
|
};
