Rob Herring 791d3ef2e1 dt-bindings: remove 'interrupt-parent' from bindings
'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.

RT5514 audio CODEC
This device supports both I2C and SPI.
Required properties:
- compatible : "realtek,rt5514".
- reg : the I2C address of the device for I2C, the chip select
number for SPI.
Optional properties:
- clocks: The phandle of the master clock to the CODEC
- clock-names: Should be "mclk"
- interrupts: The interrupt number to the cpu. The interrupt specifier format
depends on the interrupt controller.
- realtek,dmic-init-delay-ms
Set the DMIC initial delay (ms) to wait it ready for I2C.
Pins on the device (for linking into audio routes) for I2C:
* DMIC1L
* DMIC1R
* DMIC2L
* DMIC2R
* AMICL
* AMICR
Example:
rt5514: codec@57 {
compatible = "realtek,rt5514";
reg = <0x57>;
};
