- 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.
