This series try to add 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. To avoid confusion on use, i think the
new compatible string is needed.

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

Same comment as on i2c, the g12 seems compatible with the axg.
Is this patchset patchset really necessary ?

OK for the new compatible, but you can re-use the same struct like for i2c.
