Subject: [PATCH v11 tty-next 0/4] serial: 8250_pci1xxxx: Add driver for the pci1xxxx's quad-uart function
Date: Sat, 4 Feb 2023 11:01:34 +0530	[thread overview]
Message-ID: <20230204053138.2520105-1-kumaravel.thiagarajan@microchip.com> (raw)

pci1xxxx is a PCIe switch with a multi-function endpoint on one of its
downstream ports. Quad-uart is one of the functions in the multi-function
endpoint. This patch adds device driver for the quad-uart function and
enumerates between 1 to 4 instances of uarts based on the PCIe subsystem
device ID.

The changes from v1->v2->v3->v4->v5->v6->v7->v8->v9->v10->v11 are mentioned
in each patch in the patchset.

Thanks to Andy Shevchenko, Ilpo Jarvinen, Chritophe JAILLET, Geert
Uytterhoeven, Greg KH, Jiri Slaby for their review comments.
