Subject: [PATCH v5 tty-next 0/4] 8250: microchip: pci1xxxx: Add driver for the pci1xxxx's quad-uart function
Date: Thu, 17 Nov 2022 10:31:22 +0530 [thread overview]
Message-ID: <20221117050126.2966714-1-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 are mentioned in each patch in the
patchset.
Thanks to Andy Shevchenko, Ilpo Jarvinen, Chritophe JAILLET, Geert
Uytterhoeven, Greg KH for their review comments.
