This series adds GPIO interrupt controller support for Meson-G12A SoCs.
Although the total number of pins is the same as the Meson-AXG SoC, the
GPIO banks and IRQ numbers are different. Add a new compatible string
to avoid confusion when using it.
I am re-sending this update because v2 looked good in my opinion (Xingyu
Chen did good work here) but it never made it into mainline.
Changes since v1 at [1]:
- share the device data with Meson-AXG
Changes since v2 at [2]:
- dropped "Change-Id" from patch #2
- added .dts patch #3 - this should go through Kevin's linux-amlogic
tree. if required I can re-send it in a separate series

Update the dt-binding document to support new compatible string for the
GPIO interrupt controller which found in Amlogic's Meson-G12A SoC.

The Meson-G12A SoC uses the same GPIO interrupt controller IP block as the
other Meson SoCs, A totle of 100 pins can be spied on, which is the sum of:
- 223:100 undefined (no interrupt)
- 99:97 3 pins on bank GPIOE
- 96:77 20 pins on bank GPIOX
- 76:61 16 pins on bank GPIOA
- 60:53 8 pins on bank GPIOC
- 52:37 16 pins on bank BOOT
- 36:28 9 pins on bank GPIOH
- 27:12 16 pins on bank GPIOZ
- 11:0 12 pins in the AO domain

GPIO interrupts are used for the external Ethernet RGMII PHY interrupt
line.
Add the GPIO interrupt controller so we can describe that connection in
the dts files.

I've taken patches 1 and 2 into the irqchip tree. Please route patch 3
though armsoc.
Thanks,
