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.
