Driver implementer's API guide
==============================
The kernel offers a wide variety of interfaces to support the development
of device drivers. This document is an only somewhat organized collection
of some of those interfaces — it will hopefully get better over time! The
available subsections can be seen below.
General information for driver authors
======================================
This section contains documentation that should, at some point or other, be
of interest to most developers working on device drivers.
