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. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.
