Descrtiption:
This ABI shows the statistics of devfreq behavior on a

the number of transitions between states.
In order to activate this ABI, the devfreq target device
driver should provide the list of available frequencies
with its profile.

Description:
The /sys/devices/.../power/pm_qos_no_power_off attribute
is used for manipulating the PM QoS "no power off" flag. If

<title>Using uio_dmem_genirq for platform devices</title>
<para>
In addition to statically allocated memory ranges, they may also be
a desire to use dynamically allocated regions in a user space driver.
In particular, being able to access memory made available through the
dma-mapping API, may be particularly useful. The
<varname>uio_dmem_genirq</varname> driver provides a way to accomplish
this.
</para>
<para>
This driver is used in a similar manner to the
<varname>"uio_pdrv_genirq"</varname> driver with respect to interrupt
configuration and handling.
</para>
<para>
Set the <varname>.name</varname> element of
<varname>struct platform_device</varname> to
<varname>"uio_dmem_genirq"</varname> to use this driver.
</para>
<para>
When using this driver, fill in the <varname>.platform_data</varname>
element of <varname>struct platform_device</varname>, which is of type
<varname>struct uio_dmem_genirq_pdata</varname> and which contains the
following elements:
</para>
<itemizedlist>
<listitem><varname>struct uio_info uioinfo</varname>: The same
structure used as the <varname>uio_pdrv_genirq</varname> platform
data</listitem>
<listitem><varname>unsigned int *dynamic_region_sizes</varname>:
Pointer to list of sizes of dynamic memory regions to be mapped into
user space.
</listitem>
<listitem><varname>unsigned int num_dynamic_regions</varname>:
Number of elements in <varname>dynamic_region_sizes</varname> array.
</listitem>
</itemizedlist>
<para>
The dynamic regions defined in the platform data will be appended to
the <varname> mem[] </varname> array after the platform device
resources, which implies that the total number of static and dynamic
memory regions cannot exceed <varname>MAX_UIO_MAPS</varname>.
</para>
<para>
The dynamic memory regions will be allocated when the UIO device file,
<varname>/dev/uioX</varname> is opened.
Simiar to static memory resources, the memory region information for
dynamic regions is then visible via sysfs at
<varname>/sys/class/uio/uioX/maps/mapY/*</varname>.
The dynmaic memory regions will be freed when the UIO device file is
closed. When no processes are holding the device file open, the address
returned to userspace is ~0.
