[PATCH v2 0/2] irqchip/meson-gpio: Add support for Meson-G12A SoC

[Xingyu Chen]

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.

Changes since v1: [1]
- share the device data with Meson-AXG

[PATCH v2 1/2] dt-bindings: interrupt-controller: New binding for Meson-G12A SoC

[Xingyu Chen]

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

[PATCH v2 2/2] irqchip/meson-gpio: Add support for Meson-G12A SoC

[Xingyu Chen]

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

Could you resent this serie rebased on v5.1-rc1 when tagged ?

Thanks,
Neil
