This is my complete queue fo the omap serial driver based on the 8250 core
code. I played with it on beagle bone, am335x-evm and dra7xx including DMA.
The runtime-pm pieces look now bug-compatible with the omap-serial driver.
Besides the runtime-om improvement I also fixed a few corner cases for the
TX-DMA problem. The DMA fixes (in edma and omap-dma) were dropped and the
problem has been in 8250-dma via patch #13.

The whole queue is available at
  git://git.breakpoint.cc/bigeasy/linux.git uart_v8

Gave the above branch a quick try, but it again does not idle for
my omap3 test cases. It seems that now the cm_idlest1_core sdma
bit is blocking deeper idle states. Is that the correct branch
to use?

Never mind. User error. I forgot to apply my own patch for force
idling the UARTs for the omap hwmod. And the sdma bit clears if
I do sleep 5 before attempting to read the sysfs entry..

Regards,

Tony
