But the mfd driver could support the act8865 variant as well (by only
registering the regulator mfd cell).

I still don't understand.
The MFD sub device is registered as a platform device, the existing act8865 driver is registered as an i2c_driver. How do they match? :)
Could you point out which exiting driver for me to reference. Thank you!
