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)
"amlogic,meson-g12a-gpio-intc" for G12A SoCs (S905D2, S905X2, S905Y2)
"amlogic,meson-sm1-gpio-intc" for SM1 SoCs (S905D3, S905X3, S905Y3)
"amlogic,meson-a1-gpio-intc" for A1 SoCs (A113L)
"amlogic,meson-s4-gpio-intc" for S4 SoCs (S802X2, S905Y4, S805X2G, S905W2)
- 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>;
};
