Don't see any GPIOs for i2c?

I need a package to see them right? RN I'm cherry-picking my packages so there's a high probability that if this needs a package I don't have it installed (I'm saying that because I've seen the i2c section in menuconfig)

No, essentially you just look which GPIOs you have used above and then put the corresponding groups here.
I've once compiled an Excel document for that.
You more or less have to extract the information from this file: https://github.com/torvalds/linux/blob/745ec436de7223fbe086be5123fe3014c4220611/drivers/pinctrl/ralink/pinctrl-mt7621.c or from the documentation on the board.

I'll look into it soon, meanwhile the manufacturer let you download this
idk if it's useful or not, just sharing my documentation.
