Subject: [PATCH v3 7/7] misc: pci_endpoint_test: Document a policy about adding pci_device_id
Date: Mon,  1 Apr 2024 11:39:42 +0900	[thread overview]
Message-ID: <20240401023942.134704-8-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <20240401023942.134704-1-yoshihiro.shimoda.uh@renesas.com>

To avoid becoming struct pci_device_id pci_endpoint_test_tbl longer
and longer, document a policy. For example, if PCIe endpoint controller
can configure vendor id and/or product id, you can reuse one of
existing entries to test.
