Hi everyone, This patch adds the support for the external interrupt sources found in the PIO IP of the Allwinner SoCs.
This IP handles up to 32 external interrupt source, that are exposed through a particular pin function on some pins handled by the PIO. We thus need to change the muxing to enable these interrupts, which leads to some additional logic.
