- 15:14    2 pins on bank E
- 13:0    14 pins on bank B

A4 AO IRQ Number:
- 7       1 pin  on bank TESTN
- 6:0     7 pins on bank AO

A5 IRQ Number:
- 98      1 pin  on bank TESTN
- 97:82   16 pins on bank Z
- 81:62   20 pins on bank X
- 61:48   14 pins on bank T
- 47:32   16 pins on bank D
- 31:27    5 pins on bank H
- 26:25    2 pins on bank E
- 24:14   11 pins on bank C
- 13:0    14 pins on bank B

This function is a full copy of meson_s4_gpio_irq_set_type() with the
only difference of:

           s/REG_EDGE_POL_S4/REG_EDGE_POL_AO/

Can you please stick that register offset into the parameter structure
and use the function for both variants?

Thanks,
