[PATCH v2 0/7] USB31DRD phy support for Google Tensor gs101 (HS & SS)

[André Draszik]

This patch series adds support for the Exynos USB 3.1 DRD combo phy, as
found in Exynos 9 SoCs like Google GS101. It supports USB SS, HS and
DisplayPort, but DisplayPort is out of scope for this series.

In terms of UTMI+, this is very similar to the existing Exynos850
support in this driver. The difference is that it supports both UTMI+
(HS) and PIPE3 (SS). Firstly, there are some preparatory patches to simplify
addition, while the bulk of the changes is around the SS part.

This version doesn't change anything around Krzysztof's comments regarding
syscon- vs Exynos-specific PMU APIs, but I wanted to post a version with at
least the simple fixes that are necessary as well applied.
