+ *
+ * The first version was written by Martin Devera, <devik@cdi.cz>
+ *
+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
+ * - Update patch to 2.4.21
+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
+ * - Fix "Dead-loop on netdevice imq"-issue
+ * Marcel Sebek <sebek64@post.cz>
+ * - Update to 2.6.2-rc1
+ *
+ * After some time of inactivity there is a group taking care
+ * of IMQ again: http://www.linuximq.net
+ *
+ *
+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
+ * including the following changes:
+ *
+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
+ * - Correction of imq_init_devs() issue that resulted in
+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
+ * - Addition of functionality to choose number of IMQ devices
+ * during kernel config (Andre Correa)
+ * - Addition of functionality to choose how IMQ hooks on
+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
+ *
+ *
+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
+ * released with almost no problems. 2.6.14-x was released
+ * with some important changes: nfcache was removed; After
+ * some weeks of trouble we figured out that some IMQ fields
+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
+ * These functions are correctly patched by this new patch version.
+ *
+ * Thanks for all who helped to figure out all the problems with
+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
+ * I didn't forget anybody). I apologize again for my lack of time.
+ *
+ *
+ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
+ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
+ * recursive locking. New initialization routines to fix 'rmmod' not
+ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
+ *
+ * Also, many thanks to pablo Sebastian Greco for making the initial
+ * patch and to those who helped the testing.
+ *
+ * More info at: http://www.linuximq.net/ (Andre Correa)

+ Queueing (ESFQ) packet scheduling algorithm for some of your network
+ devices or as a leaf discipline for a classful qdisc such as HTB or
+ CBQ (see the top of <file:net/sched/sch_esfq.c> for details and
+ references to the SFQ algorithm).
+
+ This is an enchanced SFQ version which allows you to control some
+ hardcoded values in the SFQ scheduler.
+
+ ESFQ also adds control of the hash function used to identify packet
+ flows. The original SFQ discipline hashes by connection; ESFQ add
+ several other hashing methods, such as by src IP or by dst IP, which
+ can be more fair to users in some networking situations.
+
+ To compile this code as a module, choose M here: the
+ module will be called sch_esfq.
+
+config NET_SCH_ESFQ_NFCT

+ ---help---
+ Say Y here to enable support for hashing based on netfilter connection
+ tracking information. This is useful for a router that is also using
+ NAT to connect privately-addressed hosts to the Internet. If you want
+ to provide fair distribution of upstream bandwidth, ESFQ must use
+ connection tracking information, since all outgoing packets will share
+ the same source address.

Subject: [PATCH 2/3] I2C: at24: add kernel interface for reading/writing EEPROM
Date: Monday 25 August 2008
From: Kevin Hilman <khilman@deeprootsystems.com>
To: davinci-linux-open-source@linux.davincidsp.com
This patch adds an interface by which other kernel code can read/write
detected EEPROM.
The platform code registers a 'setup' callback with the
at24_platform_data. When the at24 driver detects an EEPROM, it fills
out the read and write functions of at24_iface and calls the setup
callback. The platform code can then use the read/write functions in
the at24_iface struct for reading and writing the EEPROM.
Original idea, review and updates by David Brownell <david-b@pacbell.net>
Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
+================================================================
+
+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
+MMC or SD card on GPIO pins.
+
+Two interfaces for registering a new MMC/SD card device are provided:
+A static platform-device based mechanism and a dynamic configfs based interface.
+
+
+Registering devices via platform-device
+=======================================
+
+The platform-device interface is used for registering MMC/SD devices that are
+part of the hardware platform. This is most useful only for embedded machines
+with MMC/SD devices statically connected to the platform GPIO bus.
+
+The data structures are declared in <linux/mmc/gpiommc.h>.
+
+To register a new device, define an instance of struct gpiommc_platform_data.
+This structure holds any information about how the device is hooked up to the
+GPIO pins and what hardware modes the device supports. See the docbook-style
+documentation in the header file for more information on the struct fields.
+
+Then allocate a new instance of a platform device by doing:
+
+ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
+
+This will allocate the platform device data structures and hook it up to the
+gpiommc driver.
+Then add the gpiommc_platform_data to the platform device.
+
+ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
+
+You may free the local instance of struct gpiommc_platform_data now. (So the
+struct may be allocated on the stack, too).
+Now simply register the platform device.
+
+ err = platform_device_add(pdev);
+
+Done. The gpiommc probe routine will be invoked now and you should see a kernel
+log message for the added device.
+
+
+Registering devices via configfs
+================================
+
+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
+hardware are a common situation.
+So we provide a dynamic interface to conveniently handle adding and removing
+devices from userspace, without the need to recompile the kernel.
+
+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
+the dynamic configuration.
+
+To create a new device, it must first be allocated with mkdir.
+The following command will allocate a device named "my_mmc":
+ mkdir /config/gpiommc/my_mmc
+
+There are several configuration files available in the new
+/config/gpiommc/my_mmc/ directory:
+
+gpio_data_in = The SPI data-IN GPIO pin number.
+gpio_data_out = The SPI data-OUT GPIO pin number.
+gpio_clock = The SPI Clock GPIO pin number.
+gpio_chipselect = The SPI Chipselect GPIO pin number.
+gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
+ If 1, Chipselect is active-LOW.
+spi_mode = The SPI data mode. Can be 0-3.
+spi_delay = Enable all delays in the lowlevel bitbanging.
+max_bus_speed = The maximum SPI bus speed. In Hertz.
+
+register = Not a configuration parameter.
+ Used to register the configured card
+ with the kernel.
+
+The device must first get configured and then registered by writing "1" to
+the "register" file.
+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
+and "gpio_chipselect" are essential and _must_ be configured before writing
+"1" to the "register" file. The registration will fail, otherwise.
+
+The default values for the other parameters are:
+gpio_chipselect_activelow = 1 (CS active-LOW)
+spi_mode = 0 (SPI_MODE_0)
+spi_delay = 1 (enabled)
+max_bus_speed = 5000000 (5 Mhz)
+
+Configuration values can not be changed after registration. To unregister
+the device, write a "0" to the "register" file. The configuration can be
+changed again after unregistering.
+
+To completely remove the device, simply rmdir the directory
+(/config/gpiommc/my_mmc in this example).
+There's no need to first unregister the device before removing it. That will
+be done automatically.
