The current support is known to be broken and
a later patch will come re-adding it using
dma engine API.

no problem.

One less driver now towards OMAP DMA
engine conversion.

indeed :-) I'll take a closer look into rx timeout IRQ, but it looks

Yep. The RX path with DMA is bit of difficult part to manage for
UART.

is this Ack for this patch only or the entire series ??

Two more patches to review and then I will do it for
full series on top of the cover-letter :-)
