Hello,
Thanks for the interest in willing to experiment with runtime PM on
OMAP.
You're observations are correct. The runtime PM core is ready, but none
of the devices have yet been adapted to the runtime PM API. We will be
converting devices over to runtime PM over the next few merge windows,
with possibly some coming as soon as 2.6.37 (watchdog, UART, GPIO, i2c)
Kevin
