[PATCH v2 0/4] irqchip/meson-gpio: Add support for Meson-A1 SoC

[Qianggui Song]

This patchset adds support for GPIO interrupt controller of Meson-A1 SoC
which use new register layout, two main things are done in the patchset
1. rework current driver
2. add a1 support

changes since v1 at [0]
 - place initial macro after the definition of param structure
 - make common data as parameter of initial macro
 - add dummy init function for previous chips

I've queued the first 3 patches. The last one can go taken via arm-soc.

Thanks,
