Revision 301fe8eeee02c570c5bd30537aff9456f7f7955c authored by Tony Lindgren on 01 February 2010, 20:34:31 UTC, committed by Tony Lindgren on 03 February 2010, 16:48:06 UTC
Currently the omap serial clocks are autoidled after 5 seconds.
However, this causes lost characters on the serial ports. As this
is considered non-standard behaviour for Linux, disable the timeout.

Note that this will also cause blocking of any deeper omap sleep
states.

To enable the autoidling of the serial ports, do something like
this for each serial port:

# echo 5 > /sys/devices/platform/serial8250.0/sleep_timeout
# echo 5 > /sys/devices/platform/serial8250.1/sleep_timeout
...
