'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.

* Altera Arria10 Development Kit System Resource Chip
|
|
|
|
Required parent device properties:
|
|
- compatible : "altr,a10sr"
|
|
- spi-max-frequency : Maximum SPI frequency.
|
|
- reg : The SPI Chip Select address for the Arria10
|
|
System Resource chip
|
|
- interrupts : The interrupt line the device is connected to.
|
|
- interrupt-controller : Marks the device node as an interrupt controller.
|
|
- #interrupt-cells : The number of cells to describe an IRQ, should be 2.
|
|
The first cell is the IRQ number.
|
|
The second cell is the flags, encoded as trigger
|
|
masks from ../interrupt-controller/interrupts.txt.
|
|
|
|
The A10SR consists of these sub-devices:
|
|
|
|
Device Description
|
|
------ ----------
|
|
a10sr_gpio GPIO Controller
|
|
a10sr_rst Reset Controller
|
|
|
|
Arria10 GPIO
|
|
Required Properties:
|
|
- compatible : Should be "altr,a10sr-gpio"
|
|
- gpio-controller : Marks the device node as a GPIO Controller.
|
|
- #gpio-cells : Should be two. The first cell is the pin number and
|
|
the second cell is used to specify flags.
|
|
See ../gpio/gpio.txt for more information.

|
|
Arria10 Peripheral PHY Reset
|
|
Required Properties:
|
