Turns out I was looking at the wrong schematics and this here is a TD24C64-C-A EEPROM which seems to be from "Shenzhen Tudi Semiconductor Co., Ltd.". There's no vendor for that in the bindings, and not sure it's worth adding one for? I'll keep the ST one unless told otherwise.

After double checking everything, we need an additional two pins driven via pinctrl to 1) guarantee the state of a bootstrapping pin to select SPI/I2C mode, 2) guarantee the state of a bootstrapping pin to select the I2C address.

The review LLM highlighted this, where I should use a dash instead of underscore in node names, will fix for v2.

I'll wait a few more days for additional feedback before sending a v2.

Cheers,
Quentin
