Subject: [PATCH net-next v2 0/3] net: ipa: fully support IPA v5.0

At long last, add the IPA and GSI register definitions, and the
configuration data required to support IPA v5.0. This enables IPA
support for the Qualcomm SDX65 SoC.

The first version of this series had build errors due to a
non-existent source file being required. This version addresses
that by changing how required files are specified in the Makefile.

Note that the second patch has some warnings about lines starting
with spaces; those spaces align text with the open parenthesis on
the previous line.

Subject: [PATCH net-next v2 1/3] net: ipa: add IPA v5.0 register definitions

Add the definitions of IPA register offsets and fields for IPA v5.0.
These are used for the SDX65 SoC.

In the Makefile, split IPA_VERSIONS to use IPA_REG_VERSIONS and
IPA_DATA_VERSIONS instead, to allow IPA register definitions for a
new version to be added separate from the IPA data.

Rename GSI_IPA_VERSIONS to be GSI_REG_VERSIONS for consistency.

Subject: [PATCH net-next v2 2/3] net: ipa: add IPA v5.0 GSI register definitions

Add the definitions of GSI register offsets and fields for IPA v5.0.
These are used for the SDX65 SoC. Increase the maximum channel and
event ring counts supported by the driver, so those implemented by
the SDX65 are supported.

Here is the summary with links:
- [net-next,v2,1/3] net: ipa: add IPA v5.0 register definitions
https://git.kernel.org/netdev/net-next/c/ed4c7d616289
- [net-next,v2,2/3] net: ipa: add IPA v5.0 GSI register definitions
https://git.kernel.org/netdev/net-next/c/faf0678ec8a0
- [net-next,v2,3/3] net: ipa: add IPA v5.0 configuration data
https://git.kernel.org/netdev/net-next/c/cb7550b44383

You are awesome, thank you!
