Since this change we don't need to have custom solutions in 8250_aspeed_vuart and 8250_of drivers, thus, drop them.

For 4.14, I've worked around these missing commits:
5909c0bf9c7a ("serial/aspeed-vuart: Implement quick throttle mechanism") 989983ea849d ("serial/aspeed-vuart: Implement rx throttling") 54e53b2e8081 ("tty: serial: 8250: pass IRQ shared flag to UART ports")
Thanks!
And queued up a backport. Older kernels are a bit trickier than that.
Thanks for backporting. Why is it trickier?
Since it's quite old bug and not many reports so far I guess we are not in hurry to fix that old kernels.
It would be quite nice to have that in v4.9 as well. My original patch was made against that tree and tested.
Hm, yes, looking at it now it doesn't look too tricky, I'm not sure what happened a few days ago :)
If you want to send me a backport I'll be happy to queue it up.
