Hi Lorenzo, That's basically the same patches sent on v12, with the acked-by from the driver's maintainer (Xiaowei Song) properly added on each patch of the series. The pcie-kirin PCIe driver contains internally a PHY interface for Kirin 960, but it misses support for Kirin 970. 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.
