On this version, the DT bindings were split on a separate patch series: https://lore.kernel.org/lkml/cover.1627637448.git.mchehab+huawei@xxxxxxxxxx/ The patches here 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.

Device 3660 (rev 01) --- v8: - Changed the drivers to follow the DT schema under discussions with Rob; - Added patches to fix powerof logic and to allow unloading the driver. v7: - Moved kirin_pcie_match to be closer to the probe function; - Improved patch description for: "PCI: kirin: add support for a PHY layer" - Added missing MODULE_*() macros on both PCI and PHY drivers; - Fixed a warning at hisilicon,phy-hi3670-pcie.yaml reported by Rob Herring's bot. v6: - Use an alternative approach, in order to keep the Kirin 960 PHY internal to the driver, in order to not break the DT schema. The PHY-specific code were made self-contained at pcie-kirin, in order to make easier to split it in the future, if needed. v5: - added "static" to hi3670_pcie_get_eyeparam() declaration on patch 6/8 v4: - dropped the DTS patch, as it depends on a PMIC-related patch series; - minor changes at the patch description; - HiKey and HiSilicon are now using the preferred CamelCase format.
