Hi,
I do not think this patch alone will work on 4.14.
An earlier pair of patches which implements the "marvell,armada-38x-uart" quirk is present on the other kernel versions, but I do see it as far back as 4.14.
The following two patches are the ones which add support for that compatible string:
b7639b0b15dd serial: 8250_dw: Limit dw8250_tx_wait_empty quirk to armada-38x devices 914eaf935ec7 serial: 8250_dw: Allow TX FIFO to drain before writing to UART_LCR
But, this patch says: Fixes: 43e28ba87708 ("ARM: dts: Use armada-370-xp as a base for armada-xp-98dx3236") and that commit showed up in 4.12.
If that is not the case, fine, I'll drop this, otherwise I just have to go off of what is given to me :)
thanks,
greg k-h
