-/* 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. */
