Nice, now it mostly works for me with off-idle too :) That is as long
as I have the DMA channels commented out in the .dts file.

This patch provides a 8250-core based UART driver for the internal OMAP
UART. The long term goal is to provide the same functionality as the
current OMAP uart driver and DMA support.
I tried to merge omap-serial code together with the 8250-core code.
There should should be hardly a noticable

If you want to change this to reduce the gap, then you have first
change 8250 core code. Currently it waits until the shift register is
empty.
Oh the 8250 normally works this way? I didn't know that.

On the other hand if you use DMA then it can handle transfers 64bytes

You can dma more than the fifo size?
Yes. The UART asserts the DMA line as long as there is
