| description: | |
| 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 or 12 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 interrupts exposed depends on the SoC. |
