Then, it adds support for Kirin 970 on a single patch. With this change, the PHY-specific device tree bindings for Kirin 960 moved to its own PHY properties.

Device 3660 (rev 01) [1] The Hikey 960 doesn't come with any internal PCIe device. Its hardware supports just an external device via a M.2 slot that doesn't support SATA. I ordered a NVMe device to test, but the vendor is currently out of supply. It should take 4-5 weeks to arrive here. I'll run an extra test on it once it arrives. --- 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.
