| |
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
