This patch series adds support for the GPIO interrupt controller found on
Amlogic's meson SoC families.

Unlike what the name suggests, this controller is not part of the SoC
GPIO subsystem. It is a separate controller from which can watch almost
all pads of the SoC and generate and interrupt from it. Some pins, which
are not part of the public datasheet, don't seem to have this capability
though.

Hardware wise, the controller is a 256 to 8 router with filtering block
to select edge or level input and the polarity of the signal.  As there
we can't setup the filtring to generate a signal on both the high and low
polarity, there is no easy way to support IRQ_TYPE_EDGE_BOTH at the
moment

The number of interrupt line routed to the controller depends on the SoC,
and essentially the number of GPIO available on the SoC.

This series has been tested on Amlogic S905-P200 board with the front
panel power button.

This work is derived from the previous work of Carlo Caione [1].

So we have two competing series, all based on the same stuff. I must say
this is rather disappointing that people can't manage to collaborate and
work towards a common goal.

I'm going to review the irqchip part, because I've done that on Heiner's
series as well, but that's where I'm going to stop.

Heiner, Jerome: please sort this out between yourselves *BEFORE* sending
any other patch series. This is wasting everybody's time, both yours and
mine (and frankly, this a rather rare commodity these days).

Thanks,

	M.
