mfd: simple-mfd-i2c: Add Delta TN48M CPLD support
Browse files Browse the repository at this point in the history
Delta TN48M switches have a Lattice CPLD that serves
multiple purposes including being a GPIO expander.

So, lets use the simple I2C MFD driver to provide the MFD core.

Also add a virtual symbol which pulls in the simple-mfd-i2c driver and
provide a common symbol on which the subdevice drivers can depend on.

Select this option to enable support for Delta Networks TN48M switch

for the SFP slots as well as power supply related information.
SFP support depends on the GPIO driver being selected.
