+ S3C24XX CPUfreq support
+ =======================
+
+Introduction
+------------
+
+ The S3C24XX series support a number of power saving systems, such as
+ the ability to change the core, memory and peripheral operating
+ frequencies. The core control is exported via the CPUFreq driver
+ which has a number of different manual or automatic controls over the
+ rate the core is running at.
+
+ There are two forms of the driver depending on the specific CPU and
+ how the clocks are arranged. The first implementation used as single
+ PLL to feed the ARM, memory and peripherals via a series of dividers
+ and muxes and this is the implementation that is documented here. A
+ newer version where there is a seperate PLL and clock divider for the
+ ARM core is available as a seperate driver.
+
+
+Layout
+------
+
+ The code core manages the CPU specific drivers, any data that they
+ need to register and the interface to the generic drivers/cpufreq
+ system. Each CPU registers a driver to control the PLL, clock dividers
+ and anything else associated with it. Any board that wants to use this
+ framework needs to supply at least basic details of what is required.
+
+ The core registers with drivers/cpufreq at init time if all the data
+ necessary has been supplied.
+
+
+CPU support
+-----------
+
+ The support for each CPU depends on the facilities provided by the
+ SoC and the driver as each device has different PLL and clock chains
+ associated with it.
+
+
+Slow Mode
+---------
+
+ The SLOW mode where the PLL is turned off altogether and the
+ system is fed by the external crystal input is currently not
+ supported.
+
+
+sysfs
+-----
+
+ The core code exports extra information via sysfs in the directory
+ devices/system/cpu/cpu0/arch-freq.
+
+
+Board Support
+-------------
+
+ Each board that wants to use the cpufreq code must register some basic
+ information with the core driver to provide information about what the
+ board requires and any restrictions being placed on it.
+
+ The board needs to supply information about whether it needs the IO bank
+ timings changing, any maximum frequency limits and information about the
+ SDRAM refresh rate.

-config NILFS2_FS
- tristate "NILFS2 file system support (EXPERIMENTAL)"
- depends on BLOCK && EXPERIMENTAL
- select CRC32
- help
- NILFS2 is a log-structured file system (LFS) supporting continuous
- snapshotting. In addition to versioning capability of the entire
- file system, users can even restore files mistakenly overwritten or
- destroyed just a few seconds ago. Since this file system can keep
- consistency like conventional LFS, it achieves quick recovery after
- system crashes.
-
- NILFS2 creates a number of checkpoints every few seconds or per
- synchronous write basis (unless there is no change). Users can
- select significant versions among continuously created checkpoints,
- and can change them into snapshots which will be preserved for long
- periods until they are changed back to checkpoints. Each
- snapshot is mountable as a read-only file system concurrently with
- its writable mount, and this feature is convenient for online backup.
-
- Some features including atime, extended attributes, and POSIX ACLs,
- are not supported yet.
-
- To compile this file system support as a module, choose M here: the
- module will be called nilfs2. If unsure, say N.

+ help
+ NILFS2 is a log-structured file system (LFS) supporting continuous
+ snapshotting. In addition to versioning capability of the entire
+ file system, users can even restore files mistakenly overwritten or
+ destroyed just a few seconds ago. Since this file system can keep
+ consistency like conventional LFS, it achieves quick recovery after
+ system crashes.
+
+ NILFS2 creates a number of checkpoints every few seconds or per
+ synchronous write basis (unless there is no change). Users can
+ select significant versions among continuously created checkpoints,
+ and can change them into snapshots which will be preserved for long
+ periods until they are changed back to checkpoints. Each
+ snapshot is mountable as a read-only file system concurrently with
+ its writable mount, and this feature is convenient for online backup.
+
+ Some features including atime, extended attributes, and POSIX ACLs,
+ are not supported yet.
+
+ To compile this file system support as a module, choose M here: the
+ module will be called nilfs2. If unsure, say N.
