Ditto.

Hmm. I'm not sure I like putting "SPI" or "I²C" or whatever (UART?
1Wire?) in the module name. There are genuinely some chips that are
available with a variety of interface types, or some even support a
selection of them by different hardware configurations or whatever. So
I think that the interface type should be an implementation detail, and
not really part of the name.

What do you think to simply

  Device::Chip::*

as the namespace for individual chips. E.g

  Device::Chip::INA219
  Device::Chip::MAX7221

I'm not sure if driver adapters (Bus Pirate, FT232H, Raspberry Pi
GPIO, etc...) would necessarily warrant a dedicated space too; they
become the consumers of these chips, much like my existing
Device::BusPirate currently consumes chips within its space.
