So we do something like this in the recent patch to the PL022 SPI driver by setting the pinctrl states inside the runtime suspend and resume callbacks: http://sourceforge.net/mailarchive/forum.php?thread_name=20120920130240.GR17666%40opensource.wolfsonmicro.com&forum_name=spi-devel-general You can very well do clocks and regulators in these functions as well. Other platforms like shmobile will use runtime pm notifications to do all this orthogonally in a central place, which may be applicable for OMAP.
