Subject: [PATCH v4 0/8] Add support for Hikey 970 PCIe
Date: Mon, 12 Jul 2021 23:46:38 +0200 [thread overview]
Message-ID: <cover.1626126198.git.mchehab+huawei@kernel.org> (raw)
As requested by Rob Herring, this series split the PHY part into a separate driver.
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.
Tested on Hikey970:

Partially tested on Hikey 960[1]:
$ lspci
00:00.0 PCI bridge: Huawei Technologies Co., Ltd. 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.
