The current support is known to be broken and a later patch will come re-adding it using dma engine API. Signed-off-by: Felipe Balbi <redacted> ---Thanks Felipe !!no problem.quoted
One less driver now towards OMAP DMA engine conversion.indeed :-) I'll take a closer look into rx timeout IRQ, but it looks like we can use it to kick dma only for "big" transfers... need to play with it for a while first, though.Yep. The RX path with DMA is bit of difficult part to manage for UART.quoted

FWIW, Acked-by: Santosh Shilimkar <redacted>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 :-)
