Wondering if we shouldn't split that driver in two symbols, one for I2C 
and one for SPI such that you don't need both if you only have a device 
over I2C/SPI.

Can you update the help text to say this supports SPI-connected GPIO 
devices as well (the SPI-connected devices are listed below, outside the 
git context but if someone doesn't know better, it'll be difficult to 
figure this out)?

With that,
