-The four functions above are just like the counterpart functions
-without the _attrs suffixes, except that they pass an optional
-struct dma_attrs*.
-
-struct dma_attrs encapsulates a set of "dma attributes". For the
-definition of struct dma_attrs see linux/dma-attrs.h.
-
-The interpretation of dma attributes is architecture-specific, and
-each attribute should be documented in Documentation/DMA-attributes.txt.
-
-If struct dma_attrs* is NULL, the semantics of each of these
-functions is identical to those of the corresponding function
-without the _attrs suffix. As a result dma_map_single_attrs()
-can generally replace dma_map_single(), etc.
-
-As an example of the use of the *_attrs functions, here's how
-you could pass an attribute DMA_ATTR_FOO when mapping memory
-for DMA:
-
-#include <linux/dma-attrs.h>
-/* DMA_ATTR_FOO should be defined in linux/dma-attrs.h and
- * documented in Documentation/DMA-attributes.txt */
-...
-
-	DEFINE_DMA_ATTRS(attrs);
-	dma_set_attr(DMA_ATTR_FOO, &attrs);
-	....
-	n = dma_map_sg_attrs(dev, sg, nents, DMA_TO_DEVICE, &attr);
-	....
-
-Architectures that care about DMA_ATTR_FOO would check for its
-presence in their implementations of the mapping and unmapping
-routines, e.g.:
-
-void whizco_dma_map_sg_attrs(struct device *dev, dma_addr_t dma_addr,
-			     size_t size, enum dma_data_direction dir,
-			     struct dma_attrs *attrs)
-{
-	....
-	int foo =  dma_get_attr(DMA_ATTR_FOO, attrs);
-	....
-	if (foo)

-	The clock framework defines programming interfaces to support
-	software management of the system clock tree.
-	This framework is widely used with System-On-Chip (SOC) platforms
-	to support power management and various devices which may need
-	custom clock rates.
-	Note that these "clocks" don't relate to timekeeping or real
-	time clocks (RTCs), each of which have separate frameworks.
-	These <structname>struct clk</structname> instances may be used
-	to manage for example a 96 MHz signal that is used to shift bits
-	into and out of peripherals or busses, or otherwise trigger
-	synchronous state machine transitions in system hardware.
-     </para>
-
-     <para>
-	Power management is supported by explicit software clock gating:
-	unused clocks are disabled, so the system doesn't waste power
-	changing the state of transistors that aren't in active use.
-	On some systems this may be backed by hardware clock gating,
-	where clocks are gated without being disabled in software.
-	Sections of chips that are powered but not clocked may be able
-	to retain their last state.
-	This low power state is often called a <emphasis>retention
-	mode</emphasis>.
-	This mode still incurs leakage currents, especially with finer
-	circuit geometries, but for CMOS circuits power is mostly used
-	by clocked state changes.
-     </para>
-
-     <para>
-	Power-aware drivers only enable their clocks when the device
-	they manage is in active use.  Also, system sleep states often
-	differ according to which clock domains are active:  while a
-	"standby" state may allow wakeup from several active domains, a
-	"mem" (suspend-to-RAM) state may require a more wholesale shutdown
-	of clocks derived from higher speed PLLs and oscillators, limiting
-	the number of possible wakeup event sources.  A driver's suspend
-	method may need to be aware of system-specific clock constraints
-	on the target sleep state.
-     </para>
-
-     <para>
-        Some platforms support programmable clock generators.  These
-	can be used by external chips of various kinds, such as other
-	CPUs, multimedia codecs, and devices with strict requirements
-	for interface clocking.
