The DT schema used by this series got merged at:
https://git.kernel.org/pub/scm/linux/kernel/git/robh/linu...
The series should apply cleanly on the top of v5.14-rc1.
patch1 contains a PHY for Kirin 970 PCIe.
The remaining patches add support for Kirin 970 at the pcie-kirin driver, and
add the needed logic to compile it as module and to allow to dynamically
remove the driver in runtime.
Tested on HiKey970:
