There is one weird data in rxfifo after one full rx/tx transfer

totally, so disable dma functhion here. And will re-enable it
once the root cause found.

Hmm, I experience problems with DMA too but on uart3. I'm using the same
workaround for the uart (I've just commented out the dma entries in the DT).
The problem manifests itself here such, that brcm_patchram_plus
hangs while uploading the firmware to a BCM4330 connected at uart3
(reproducible).

Yes, we just have fixed the BT issue over high speed UART last month. Suggest
you trying our patches based on v3.10.

Thanks for the pointer. Will look if I will find these patches.

Regards,

Alexander Holler
