You say they are chips so they are integrated circuits (ICs), they are designed to solve some specific needs, so they are application-specific ICs, i.e. ASICs, what's the problem?

Interesting what are they? Power management ICs? Power management + audio + touchscreen + ADC + USB transceiver + UART + whatever all such chips may be considered as ASICs.

That different functionality blocks will be handled by appropriate device drivers, and in general the drivers should not depend on a particular ASIC but use common ASIC API. But "common functionality" drivers are ASIC-specific.

Perhaps, so. Actually, MFD (multi functional device) doesn't imply a platform-level device but ASIC seems does.
Thanks, Dmitry
