In linux kernel since version 5.2 (release Date: 2019-07-07)  
This enables support for the GPIOs found on the Delta
Networks TN48M switch Lattice CPLD. It provides 12 pins in total,
they are input-only or output-only type.

This driver can also be built as a module. If so, the
module will be called gpio-tn48m.
