Subject: [PATCH 2/2] PCI: switchtec: Add support for PCIe Gen5 devices
Date: Fri, 23 Jun 2023 17:00:03 -0700	[thread overview]
Message-ID: <20230624000003.2315364-3-kelvin.cao@microchip.com> (raw)
In-Reply-To: <20230624000003.2315364-1-kelvin.cao@microchip.com>

From: Kelvin Cao <kelvin.cao@microchip.com>

Advertise support of Gen5 devices in the driver's device ID table and
add the same IDs for the switchtec quirks. Also update driver code to
accommodate them.
