'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.

Amlogic meson GPIO interrupt controller
|
|
|
|
Meson SoCs contains an interrupt controller which is able to watch the SoC
|
|
pads and generate an interrupt on edge or level. The controller is essentially
|
|
a 256 pads to 8 GIC interrupt multiplexer, with a filter block to select edge
|
|
or level and polarity. It does not expose all 256 mux inputs because the
|
|
documentation shows that the upper part is not mapped to any pad. The actual
|
|
number of interrupt exposed depends on the SoC.
|
|
|
|
Required properties:
|
|
|
|
- compatible : must have "amlogic,meson8-gpio-intc" and either
|
|
"amlogic,meson8-gpio-intc" for meson8 SoCs (S802) or
|
|
"amlogic,meson8b-gpio-intc" for meson8b SoCs (S805) or
|
|
"amlogic,meson-gxbb-gpio-intc" for GXBB SoCs (S905) or
|
|
"amlogic,meson-gxl-gpio-intc" for GXL SoCs (S905X, S912)
|
|
"amlogic,meson-axg-gpio-intc" for AXG SoCs (A113D, A113X)
|
|
- reg : Specifies base physical address and size of the registers.
|
|
- interrupt-controller : Identifies the node as an interrupt controller.
|
|
- #interrupt-cells : Specifies the number of cells needed to encode an
|
|
interrupt source. The value must be 2.
|
|
- meson,channel-interrupts: Array with the 8 upstream hwirq numbers. These
|
|
are the hwirqs used on the parent interrupt controller.
|
|
|
|
Example:
|
|
|
|
gpio_interrupt: interrupt-controller@9880 {
|
|
compatible = "amlogic,meson-gxbb-gpio-intc",
|
|
"amlogic,meson-gpio-intc";
|
|
reg = <0x0 0x9880 0x0 0x10>;
|
|
interrupt-controller;
|
|
#interrupt-cells = <2>;
|
|
meson,channel-interrupts = <64 65 66 67 68 69 70 71>;
|
|
};
