I misunderstood.  It still needs the compatible string to match the
corresponding driver.

No, it doesn't.  The MFD should be registering the platform device.

I guess I see.  It lists the mfd_cell when calling
devm_mfd_add_devices() in drivers/mfd/mt6397-core.c.  It falls back to
use driver name and device name to match.  As long as the name
provided in mfd_cell matches the platform driver name, it works.

But I found struct mfd_cell also contains member .of_compatible.  What
is the difference if we use compatible string (as is) for this device
instead of falling back to use device name to match?
