Hello Robin,
Sorry for inconvenience. Since I don't adhere enabling DMA for UARTs,
please revert my patch if you need.
BTW, there are DMA properties in RK3328 device-tree like as this patch.
RK3328 UART DMA could not work correctly too...??
Best Regards,
Katsuhiro Suzuki

As a heads-up, I did manage to try my board with this patch applied over
the weekend, and it makes probing the bluetooth adapter fail with
communication errors, so I'm not sure the 8250 and pl330 drivers are
really cooperating well enough :(
Robin.
