Here's v3 of the outstanding fixes for Oxford Semiconductor 950 UARTs. As the change for the default FIFO rx trigger level has been already merged with commit d7aff291d069 ("serial: 8250: Define RX trigger levels for OxSemi 950 devices") only one patch of the original series remains. However in the course of preparing v3 of that change I have noticed that the EndRun device is actually also an OxSemi 952 device in disguise (note that the OxSemi chips have fully customer-programmable PCI vendor:device ID values). Therefore it requires a similar fix to the base baud rate as with commit 6cbe45d8ac93 ("serial: 8250: Correct the clock for OxSemi PCIe devices"), and also duplicate code can be removed. I have therefore added a fix for the EndRun device as 1/2 in this version and the original outstanding change is now 2/2, updated accordingly, also for a change in the handling of the MCR made with commit b4a29b94804c ("serial: 8250: Move Alpha-specific quirk out of the core"). As noted in the course of v2 review I don't believe the Linux kernel has a policy for any of its subsystems to require rewriting parts of existing code to fix bugs or internal API deficiencies as a prerequisite for bug fix (or even functional improvement) acceptance. Therefore I consider this v3 of the series final and I am not going to continue pursuing this submission any further unless there is an actual technical defect (a bug, a coding style issue, etc.) within this series itself.
