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.

* Ingenic JZ4780 I2C Bus controller
Required properties:
- compatible: should be "ingenic,jz4780-i2c"
- reg: Should contain the address & size of the I2C controller registers.
- interrupts: Should specify the interrupt provided by parent.
- clocks: Should contain a single clock specifier for the JZ4780 I2C clock.
- clock-frequency: desired I2C bus clock frequency in Hz.
Recommended properties:
- pinctrl-names: should be "default";
- pinctrl-0: phandle to pinctrl function
Example
/ {
i2c4: i2c4@10054000 {
compatible = "ingenic,jz4780-i2c";
reg = <0x10054000 0x1000>;
interrupt-parent = <&intc>;
interrupts = <56>;
clocks = <&cgu JZ4780_CLK_SMB4>;
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pins_i2c4_data>;
};
};
