-/* This implements an i2c-core-like thing for ISA hardware monitoring
- chips. Such chips are linked to the i2c subsystem for historical
- reasons (because the early ISA hardware monitoring chips such as the
- LM78 had both an I2C and an ISA interface). They used to be
- registered with the main i2c-core, but as a first step in the
- direction of a clean separation between I2C and ISA chip drivers,
- we now have this separate core for ISA ones. It is significantly
- more simple than the real one, of course, because we don't have to
- handle multiple busses: there is only one (fake) ISA adapter.
- It is worth noting that we still rely on i2c-core for some things
- at the moment - but hopefully this won't last. */
