	Update "ipa_reg.h" so that register definitions support IPA hardware version 4.5, in addition to versions 3.5.1 through v4.2. Most of the register definitions are the same, but in some cases fields are added, changed, or eliminated. Updates for a few IPA v4.5 registers are more complex, and adding those definition will be deferred to separate patches. This patch only updates the register offset and field definitions, and adds informational comments. The only code change avoids accessing the backward compatibility register for IPA version 4.5 in ipa_hardware_config(). Other IPA v4.5-specific code changes will come later.

2020-03-08	soc: qcom: ipa: main code	Alex Elder
	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.
