[PATCH 0/5] serial: pl011: Fix DMA issues on 64bit PL330 based systems

[Andrew Jackson]

This patch set fixes a number of issues found when using
DMA driven UART transfers on the PL011 UART through a
DMA330 DMA controller on a 64bit system.

Andrew Jackson (5):
  serial: pl011: Allocate TX DMA buffer from DMA capable memory
  serial: pl011: Avoid assumptions about buffer size when refilling TX
    DMA
  serial: pl011: Set length of DMA transfer
  serial: pl011: Don't enable RX DMA if residue processing not
    supported
  serial: pl011: Add device tree support for RX DMA polling
