Steven Royer had previously attempted to upstream this
driver two years ago, but never got the chance to address
the concerns from Greg Kroah-Hartman.

The thread with the initial upstream is:
https://lkml.org/lkml/2016/2/16/918

I have addressed the following:
- Documentation
- Use of dev_dbg instead of pr_dbg
- Change to misc class
- Fixed memory barrier usages
- Addressed styling, checkpatch, renaming of functions
- General fixes to the driver to make it more inline with
  existing upstream drivers.
