This patch includes three source files that represent some basic "main
program" code for the IPA driver. They are:
- "ipa.h" defines the top-level IPA structure which represents an IPA
device throughout the code.
- "ipa_main.c" contains the platform driver probe function, along with
some general code used during initialization.
- "ipa_reg.h" defines the offsets of the 32-bit registers used for the
IPA device, along with masks that define the position and width of
fields within these registers.
- "version.h" defines some symbolic IPA version numbers.
Each file includes some documentation that provides a little more
overview of how the code is organized and used.
