|
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.
