Thanks Dinh & Alexander for the intergration testing.
Can you test it again with the patch?

Hello!SoCFPGA is using the 8250_dw.c uart driver.
Bartlomiej, could you please tell what uart driver is used on Samsung
Dinh, could you please tell what uart driver is used on SoCFPGA?
Could you make two test?This case still fails for me.
1) Checkout tree at commit 848e9776fee4 "dmaengine: pl330: support
burst mode for
dev-to-mem and mem-to-dev transmit", make it buildable and see is it
works. In order to make in buildable remove bursts argument from the
if (*bursts == 1)
- return _bursts(pl330, dry_run, buf, pxs, 1);
+ return _bursts(dry_run, buf, pxs, 1);
2) Checkout next-20160211 kernel tree and set src_maxburst andThis case works and the UART is able to operate in DMA mode.
dst_maxburst to 1 inside UART driver to see is it works?
