I agree with your reasoning, but not with dropping the Rx code altogether. However we should also drop my patch so we restore the opt-in-only characteristic until we can rootcause this. Greg can you please drop or revert commit 17438217a6f5e33d920ed3821a4b857311cc2872 "serial: pl011: use DMA RX polling by default" from the TTY tree until this has been sorted out?
