[PATCH v3 tty-next 0/3] 8250: microchip: pci1xxxx: Add driver for the pci1xxxx's quad-uart function

[Kumaravel Thiagarajan]

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 are mentioned in each patch in the patchset.

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