+ S3C2410 DMA
+ ===========
+
+Introduction
+------------
+
+ The kernel provides an interface to manage DMA transfers
+ using the DMA channels in the cpu, so that the central
+ duty of managing channel mappings, and programming the
+ channel generators is in one place.
+
+
+DMA Channel Ordering
+--------------------
+
+ Many of the range do not have connections for the DMA
+ channels to all sources, which means that some devices
+ have a restricted number of channels that can be used.
+
+ To allow flexibilty for each cpu type and board, the
+ dma code can be given an dma ordering structure which
+ allows the order of channel search to be specified, as
+ well as allowing the prohibition of certain claims.
+
+ struct s3c24xx_dma_order has a list of channels, and
+ each channel within has a slot for a list of dma
+ channel numbers. The slots are searched in order, for
+ the presence of a dma channel number with DMA_CH_VALID
+ orred in.
+
+ If the order has the flag DMA_CH_NEVER set, then after
+ checking the channel list, the system will return no
+ found channel, thus denying the request.
+
+ A board support file can call s3c24xx_dma_order_set()
+ to register an complete ordering set. The routine will
+ copy the data, so the original can be discared with
+ __initdata.

The Samsung S3C24XX range of ARM9 System-on-Chip CPUs are supported
by the 's3c2410' architecture of ARM Linux. Currently the S3C2410,
- S3C2440 and S3C2442 devices are supported.
+ S3C2412, S3C2413, S3C2440 and S3C2442 devices are supported.
Support for the S3C2400 series is in progress.
- Support for the S3C2412 and S3C2413 CPUs is being merged.

Configuration
-------------
please check the machine specific documentation.
+Layout
+------
+
+ The core support files are located in the platform code contained in
+ arch/arm/plat-s3c24xx with headers in include/asm-arm/plat-s3c24xx.
+ This directory should be kept to items shared between the platform
+ code (arch/arm/plat-s3c24xx) and the arch/arm/mach-s3c24* code.
+
+ Each cpu has a directory with the support files for it, and the
+ machines that carry the device. For example S3C2410 is contained
+ in arch/arm/mach-s3c2410 and S3C2440 in arch/arm/mach-s3c2440
+
+ Register, kernel and platform data definitions are held in the
+ include/asm-arm/arch-s3c2410 directory.

-<<<<<<< test:Documentation/feature-removal-schedule.txt
-What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY)
-When: 2.6.21
-Why: hotkey.c was an attempt to consolidate multiple drivers that use
- ACPI to implement hotkeys. However, hotkeys are not documented
- in the ACPI specification, so the drivers used undocumented
- vendor-specific hooks and turned out to be more different than
- the same.
-
- Further, the keys and the features supplied by each platform
- are different, so there will always be a need for
- platform-specific drivers.
-
- So the new plan is to delete hotkey.c and instead, work on the
- platform specific drivers to try to make them look the same
- to the user when they supply the same features.
-
- hotkey.c has always depended on CONFIG_EXPERIMENTAL

+Sony Notebook Control Driver (SNC) Readme
+-----------------------------------------
+ Copyright (C) 2004- 2005 Stelian Pop <stelian@popies.net>
+ Copyright (C) 2007 Mattia Dongili <malattia@linux.it>
+
+This mini-driver drives the SNC device present in the ACPI BIOS of
+the Sony Vaio laptops.
+
+It gives access to some extra laptop functionalities. In its current
+form, this driver let the user set or query the screen brightness
+through the backlight subsystem and remove/apply power to some devices.
+
+Backlight control:
+------------------
+If your laptop model supports it, you will find sysfs files in the
+/sys/class/backlight/sony/
+directory. You will be able to query and set the current screen
+brightness:
+ brightness get/set screen brightness (an iteger
+ between 0 and 7)
+ actual_brightness reading from this file will query the HW
+ to get real brightness value
+ max_brightness the maximum brightness value
+
+
+Platform specific:
+------------------
+Loading the sony-laptop module will create a
+/sys/devices/platform/sony-laptop/
+directory populated with some files.
+
+You then read/write integer values from/to those files by using
+standard UNIX tools.
+
+The files are:
+ brightness_default screen brightness which will be set
+ when the laptop will be rebooted
+ cdpower power on/off the internal CD drive
+ audiopower power on/off the internal sound card
+ lanpower power on/off the internal ethernet card
+ (only in debug mode)
+
+Note that some files may be missing if they are not supported
+by your particular laptop model.
+
+Example usage:
+ # echo "1" > /sys/devices/platform/sony-laptop/brightness_default
+sets the lowest screen brightness for the next and later reboots,
+ # echo "8" > /sys/devices/platform/sony-laptop/brightness_default
+sets the highest screen brightness for the next and later reboots,
+ # cat /sys/devices/platform/sony-laptop/brightness_default
+retrieves the value.
+
+ # echo "0" > /sys/devices/platform/sony-laptop/audiopower
+powers off the sound card,
+ # echo "1" > /sys/devices/platform/sony-laptop/audiopower
+powers on the sound card.
+
+Development:
+------------
+
+If you want to help with the development of this driver (and
+you are not afraid of any side effects doing strange things with
+your ACPI BIOS could have on your laptop), load the driver and
+pass the option 'debug=1'.
+
+REPEAT: DON'T DO THIS IF YOU DON'T LIKE RISKY BUSINESS.
+
+In your kernel logs you will find the list of all ACPI methods
+the SNC device has on your laptop. You can see the GCDP/GCDP methods
+used to pwer on/off the CD drive, but there are others.
+
+I HAVE NO IDEA WHAT THOSE METHODS DO.
+
+The sony-laptop driver creates, for some of those methods (the most
+current ones found on several Vaio models), an entry under
+/sys/devices/platform/sony-laptop, just like the 'cdpower' one.
+You can create other entries corresponding to your own laptop methods by
+further editing the source (see the 'sony_acpi_values' table, and add a new
+entry to this table with your get/set method names using the
+HANDLE_NAMES macro).
+
+Your mission, should you accept it, is to try finding out what
+those entries are for, by reading/writing random values from/to those
+files and find out what is the impact on your laptop.
+
+Should you find anything interesting, please report it back to me,
+I will not disavow all knowledge of your actions :)
+
+Bugs/Limitations:
+-----------------
+
+* This driver is not based on official documentation from Sony
+ (because there is none), so there is no guarantee this driver
+ will work at all, or do the right thing. Although this hasn't
+ happened to me, this driver could do very bad things to your
+ laptop, including permanent damage.
+
+* The sony-laptop and sonypi drivers do not interact at all. In the
+ future, sonypi could use sony-laptop to do (part of) its business.
+
+* spicctrl, which is the userspace tool used to communicate with the
+ sonypi driver (through /dev/sonypi) does not try to use the
+ sony-laptop driver. In the future, spicctrl could try sonypi first,
+ and if it isn't present, try sony-laptop instead.

- help
- Choice of which UART port to use for the low-level messages,
- such as the `Uncompressing...` at start time. The value of
- this configuration should be between zero and two. The port
- must have been initialised by the boot-loader before use.
-
- Note, this does not affect the port used by the debug messages,
- which is a separate configuration.
