[PATCH 0/4] 8250: DMA Fixes

[Ilpo Järvinen <ilpo.jarvinen@xxxxxxxxxxxxxxx>]

Here are a number of 8250 DMA related fixes. The last one seems the
most serious problem able to corrupt the payload ordering.

Ilpo Järvinen (4):
  serial: 8250: Fall back to non-DMA Rx if IIR_RDI occurs
  serial: 8250_lpss: Configure DMA also w/o DMA filter
  serial: 8250_lpss: Use 16B DMA burst with Elkhart Lake
  serial: 8250: Flush DMA Rx on RLSI
