Hi Rob, It follows the patchset adding a DT schema needed to power on and to use the integrated USB HUB found on HiKey 960 and Hikey 970 boards. The entire series which contains the remaining patches to support PCI and USB on HiKey970, and USB on HiKey960 was updated at: https://github.com/mchehab/linux/commits/linux-next Those patches are based on linux-next tree (next-20210831), as they depend on some patches that will likely be merged up to v5.15-rc1.
