What:	/sys/devices/.../power/state

	dev->power.power_state

	dpm_runtime_{suspend,resume)()

When:	July 2007

Why:	Broken design for runtime control over driver power states, confusing

	driver-internal runtime power management with:  mechanisms to support

	system-wide sleep state transitions; event codes that distinguish

	different phases of swsusp "sleep" transitions; and userspace policy

	inputs.  This framework was never widely used, and most attempts to

	use it were broken.  Drivers should instead be exposing domain-specific

	interfaces either to kernel or to userspace.

Who:	Pavel Machek <pavel@suse.cz>

What:	RAW driver (CONFIG_RAW_DRIVER)

When:	December 2005

Why:	declared obsolete since kernel 2.6.3
