Can you rebase it against Linus's latest, or linux-next and resend? thanks, greg k-h
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 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.
