[PATCH 0/4] Add external interrupt support for Allwinner SoCs

[Maxime Ripard <maxime.ripard@free-electrons.com>]

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.

Thanks,
Maxime
