but here is it: https://github.com/apache/nuttx/blob/master/drivers/ioexpander/mcp23x08.h @paolovolpi

But it's not the required header, as an example take a look to mcp23x17, there is an header under drivers/ioexpander and another under include/nuttx/ioexpander.

@paolovolpi good finding, actually it was missing in my PR: 4b67e23

Could you please use mcp23x17.h as base and create the mcp23x08.h? If you need help, please ping me or we can discuss it at Discord: https://discord.gg/YaqhJjHF95
