 While that's true, I don't see a need for IRQ bank on port A - this

Ah, of course they mention it in their -pinctrl.dtsi...

So with those numbers from their .dtsi I can offer to use the array as
Clément showed above, and adjust the indicies in the pin arrays above.
Then have the IRQ numbers as shown in the BSP in our .dtsi.
But I would not have SUNXI_FUNCTION_IRQ_BANK statements for those
unknown ports, in fact no mentions of PortD and PortE at all.

Does that sound acceptable?

[linux-sunxi] [PATCH 2/8] pinctrl: sunxi: Add support for the Allwinner H616 pin controller

2020-12-02 Thread Andre Przywara 
Port A is used for an internal connection to some analogue circuitry
which looks like an AC200 IP (as in the H6), though this is not
mentioned in the manual.
