The DT schema used by this series got merged at: https://git.kernel.org/pub/scm/linux/kernel/git/robh/linux.git/log/?h=dt/next 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.
