[3/3] irqchip/meson-gpio: add support for Meson-AXG SoCs

Commit Message

Yixun Lan April 8, 2018, 2:57 p.m. UTC

The Meson-AXG SoC uses the same GPIO interrupt controller IP block as the other
Meson SoCs. A total of 100 pins can be spied on, which is the sum of:
- 255:100 Undefined(no interrupt)
- 99:84, 16 pins on bank GPIOY
- 83:61, 23 pins on bank GPIOX
- 60:40, 21 pins on bank GPIOA
- 39:25, 15 pins on bank BOOT
- 24:14, 11 pins on bank GPIOZ
- 13:0 , 14 pins in the AO domain
