A customer wants to use a particular SOM, and in particular the QSPI interface.
I said that the QSPI interface is busy with onboard NAND, and can't be used via the main connectors.
They replied with a ChatGPT screenshot saying "yes, we can use it, we just need to do ${pinmux}".
They replied ~1 hr later saying that they don't want to use the specific module anymore.
I took a brief look at the ChatGPT screenshot and the SOM docs, and unsurprisingly the pins ChatGPT nominated are mostly LVDS, but also a hard GND pin.
Yay, winning.
