The same string is used for 2 muxes.
I think we should drop one for the moment or introduce a new string.

The BSP driver seems to have more than 5 IRQ Banks.
static const unsigned sun50iw9p1_irq_bank_base[] = {
SUNXI_PIO_BANK_BASE(PA_BASE, 0),
SUNXI_PIO_BANK_BASE(PC_BASE, 1),
SUNXI_PIO_BANK_BASE(PD_BASE, 2),
SUNXI_PIO_BANK_BASE(PE_BASE, 3),
SUNXI_PIO_BANK_BASE(PF_BASE, 4),
SUNXI_PIO_BANK_BASE(PG_BASE, 5),
SUNXI_PIO_BANK_BASE(PH_BASE, 6),
SUNXI_PIO_BANK_BASE(PI_BASE, 7),
};
So maybe it should be somethings like this:
static const unsigned int h616_irq_bank_map[] = { 0, 2, 3, 4, 5, 6, 7, 8 };

This is a new compatible and should be documented.
