For examples of already existing generic drivers that will also be good
examples for any other kernel drivers you want to author, refer to

For any kind of mass produced system you want to support, such as servers,
laptops, phones, tablets, routers, and any consumer or office or business goods
using appropriate kernel drivers is paramount. Submit your code for inclusion
in the upstream Linux kernel when you feel it is mature enough and you will get

In Linux GPIO lines also have a userspace ABI.
