Subject: [PATCH net-next 0/6] net: ipa: add support for IPA v3.1

This series adds support for IPA v3.1, used by the Qualcomm
Snapdragon 835 (MSM8998).

The first patch adds "qcom,msm8998-ipa" to the DT binding.

The next four patches add code to ensure correct operation on
IPA v3.1:
  - Avoid touching unsupported inter-EE interrupt mask registers
  - Set the proper flags in the clock configuration register
  - Work around the lack of an IPA FLAVOR_0 register
  - Work around the lack of a GSI PARAM_2 register

The last patch defines configuration data for this version of IPA.

Many thanks are due to AngeloGioacchino Del Regno and Jami Kettunen,
both associated with SoMainline.  Angelo first posted code to
implement most of what was required for this, and Jami has been
helpful testing these changes on his hardware.
