[PATCH 0/3] OMAP: PM: enable UART clock disabling when idle

[Kevin Hilman <khilman@deeprootsystems.com>]

This series enables UART clock disabling after an inactivity period.
It is based on top of the 2 8250 patches recently sent to linux-serial
and CC'd to linux-omap.

To enable:

  # echo 1 > /sys/power/clocks_off_while_idle
  # echo 1 > /sys/power/sleep_while_idle

NOTE: it is expected that the first character typed is lost
when coming out of idle.  The first char serves as the wakeup
event but is lost.
