Probing and attaching
=====================
+The Linux I2C stack was originally written to support access to hardware
+monitoring chips on PC motherboards, and thus it embeds some assumptions
+that are more appropriate to SMBus (and PCs) than to I2C. One of these
+assumptions is that most adapters and devices drivers support the SMBUS_QUICK
+protocol to probe device presence. Another is that devices and their drivers
+can be sufficiently configured using only such probe primitives.
+
+As Linux and its I2C stack became more widely used in embedded systems
+and complex components such as DVB adapters, those assumptions became more
+problematic. Drivers for I2C devices that issue interrupts need more (and
+different) configuration information, as do drivers handling chip variants
+that can't be distinguished by protocol probing, or which need some board
+specific information to operate correctly.
+
+Accordingly, the I2C stack now has two models for associating I2C devices
+with their drivers: the original "legacy" model, and a newer one that's
+fully compatible with the Linux 2.6 driver model. These models do not mix,
+since the "legacy" model requires drivers to create "i2c_client" device
+objects after SMBus style probing, while the Linux driver model expects
+drivers to be given such device objects in their probe() routines.
+
+
+Standard Driver Model Binding ("New Style")
+-------------------------------------------
+
+System infrastructure, typically board-specific initialization code or
+boot firmware, reports what I2C devices exist. For example, there may be
+a table, in the kernel or from the boot loader, identifying I2C devices
+and linking them to board-specific configuration information about IRQs
+and other wiring artifacts, chip type, and so on. That could be used to
+create i2c_client objects for each I2C device.
+
+I2C device drivers using this binding model work just like any other
+kind of driver in Linux: they provide a probe() method to bind to
+those devices, and a remove() method to unbind.
+
+ static int foo_probe(struct i2c_client *client);
+ static int foo_remove(struct i2c_client *client);
+
+Remember that the i2c_driver does not create those client handles. The
+handle may be used during foo_probe(). If foo_probe() reports success
+(zero not a negative status code) it may save the handle and use it until
+foo_remove() returns. That binding model is used by most Linux drivers.
+
+Drivers match devices when i2c_client.driver_name and the driver name are
+the same; this approach is used in several other busses that don't have
+device typing support in the hardware. The driver and module name should
+match, so hotplug/coldplug mechanisms will modprobe the driver.
+
+
+Device Creation (Standard driver model)
+---------------------------------------
+
+If you know for a fact that an I2C device is connected to a given I2C bus,
+you can instantiate that device by simply filling an i2c_board_info
+structure with the device address and driver name, and calling
+i2c_new_device(). This will create the device, then the driver core will
+take care of finding the right driver and will call its probe() method.
+If a driver supports different device types, you can specify the type you
+want using the type field. You can also specify an IRQ and platform data
+if needed.
+
+Sometimes you know that a device is connected to a given I2C bus, but you
+don't know the exact address it uses. This happens on TV adapters for
+example, where the same driver supports dozens of slightly different
+models, and I2C device addresses change from one model to the next. In
+that case, you can use the i2c_new_probed_device() variant, which is
+similar to i2c_new_device(), except that it takes an additional list of
+possible I2C addresses to probe. A device is created for the first
+responsive address in the list. If you expect more than one device to be
+present in the address range, simply call i2c_new_probed_device() that
+many times.
+
+The call to i2c_new_device() or i2c_new_probed_device() typically happens
+in the I2C bus driver. You may want to save the returned i2c_client
+reference for later use.
+
+
+Device Deletion (Standard driver model)
+---------------------------------------
+
+Each I2C device which has been created using i2c_new_device() or
+i2c_new_probed_device() can be unregistered by calling
+i2c_unregister_device(). If you don't call it explicitly, it will be
+called automatically before the underlying I2C bus itself is removed, as a
+device can't survive its parent in the device driver model.
+
+
+Legacy Driver Binding Model
+---------------------------
+
Most i2c devices can be present on several i2c addresses; for some this
is determined in hardware (by soldering some chip pins to Vcc or Ground),
for others this can be changed in software (by writing to specific client

-The sensors sysctl/proc interface
-=================================
-
-This section only applies if you write `sensors' drivers.
-
-Each sensors driver creates a directory in /proc/sys/dev/sensors for each
-registered client. The directory is called something like foo-i2c-4-65.
-The sensors module helps you to do this as easily as possible.
-
-The template
-------------
-
-You will need to define a ctl_table template. This template will automatically
-be copied to a newly allocated structure and filled in where necessary when
-you call sensors_register_entry.
-
-First, I will give an example definition.
- static ctl_table foo_dir_table_template[] = {
- { FOO_SYSCTL_FUNC1, "func1", NULL, 0, 0644, NULL, &i2c_proc_real,
- &i2c_sysctl_real,NULL,&foo_func },
- { FOO_SYSCTL_FUNC2, "func2", NULL, 0, 0644, NULL, &i2c_proc_real,
- &i2c_sysctl_real,NULL,&foo_func },
- { FOO_SYSCTL_DATA, "data", NULL, 0, 0644, NULL, &i2c_proc_real,
- &i2c_sysctl_real,NULL,&foo_data },
- { 0 }
- };
-
-In the above example, three entries are defined. They can either be
-accessed through the /proc interface, in the /proc/sys/dev/sensors/*
-directories, as files named func1, func2 and data, or alternatively
-through the sysctl interface, in the appropriate table, with identifiers
-FOO_SYSCTL_FUNC1, FOO_SYSCTL_FUNC2 and FOO_SYSCTL_DATA.
-
-The third, sixth and ninth parameters should always be NULL, and the
-fourth should always be 0. The fifth is the mode of the /proc file;
-0644 is safe, as the file will be owned by root:root.
-
-The seventh and eighth parameters should be &i2c_proc_real and
-&i2c_sysctl_real if you want to export lists of reals (scaled
-integers). You can also use your own function for them, as usual.
-Finally, the last parameter is the call-back to gather the data
-(see below) if you use the *_proc_real functions.
-
-
-Gathering the data
-------------------
-
-The call back functions (foo_func and foo_data in the above example)
-can be called in several ways; the operation parameter determines
-what should be done:
-
- * If operation == SENSORS_PROC_REAL_INFO, you must return the
- magnitude (scaling) in nrels_mag;
- * If operation == SENSORS_PROC_REAL_READ, you must read information
- from the chip and return it in results. The number of integers
- to display should be put in nrels_mag;
- * If operation == SENSORS_PROC_REAL_WRITE, you must write the
- supplied information to the chip. nrels_mag will contain the number
- of integers, results the integers themselves.
-
-The *_proc_real functions will display the elements as reals for the
-/proc interface. If you set the magnitude to 2, and supply 345 for
-SENSORS_PROC_REAL_READ, it would display 3.45; and if the user would
-write 45.6 to the /proc file, it would be returned as 4560 for
-SENSORS_PROC_REAL_WRITE. A magnitude may even be negative!
-
-An example function:
-
- /* FOO_FROM_REG and FOO_TO_REG translate between scaled values and
- register values. Note the use of the read cache. */
- void foo_in(struct i2c_client *client, int operation, int ctl_name,
- int *nrels_mag, long *results)
- {
- struct foo_data *data = client->data;
- int nr = ctl_name - FOO_SYSCTL_FUNC1; /* reduce to 0 upwards */
-
- if (operation == SENSORS_PROC_REAL_INFO)
- *nrels_mag = 2;
- else if (operation == SENSORS_PROC_REAL_READ) {
- /* Update the readings cache (if necessary) */
- foo_update_client(client);
- /* Get the readings from the cache */
- results[0] = FOO_FROM_REG(data->foo_func_base[nr]);
- results[1] = FOO_FROM_REG(data->foo_func_more[nr]);
- results[2] = FOO_FROM_REG(data->foo_func_readonly[nr]);
- *nrels_mag = 2;
- } else if (operation == SENSORS_PROC_REAL_WRITE) {
- if (*nrels_mag >= 1) {
- /* Update the cache */
- data->foo_base[nr] = FOO_TO_REG(results[0]);
- /* Update the chip */
- foo_write_value(client,FOO_REG_FUNC_BASE(nr),data->foo_base[nr]);
- }
- if (*nrels_mag >= 2) {
- /* Update the cache */
- data->foo_more[nr] = FOO_TO_REG(results[1]);
- /* Update the chip */
- foo_write_value(client,FOO_REG_FUNC_MORE(nr),data->foo_more[nr]);
- }
- }
- }

+ * Meta-Ctrl-A (0x81) ...
+ *
+ * - The parentheses on the keypad send '(' and ')' with all
+ * modifiers (as would do e.g. keypad '+'), but they cannot be used as
+ * application keys (i.e. sending Esc O c).
+ *
+ * - HELP and UNDO are mapped to be F21 and F24, resp, that send the
+ * codes "\E[M" and "\E[P". (This is better than the old mapping to
+ * F11 and F12, because these codes are on Shift+F1/2 anyway.) This
+ * way, applications that allow their own keyboard mappings
+ * (e.g. tcsh, X Windows) can be configured to use them in the way
+ * the label suggests (providing help or undoing).
+ *
+ * - Console switching is done with Alt+Fx (consoles 1..10) and
+ * Shift+Alt+Fx (consoles 11..20).
+ *
+ * - The misc. special function implemented in the kernel are mapped
+ * to the following key combinations:
+ *
+ * ClrHome -> Home/Find
+ * Shift + ClrHome -> End/Select
+ * Shift + Up -> Page Up
+ * Shift + Down -> Page Down
+ * Alt + Help -> show system status
+ * Shift + Help -> show memory info
+ * Ctrl + Help -> show registers
+ * Ctrl + Alt + Del -> Reboot
+ * Alt + Undo -> switch to last console
+ * Shift + Undo -> send interrupt
+ * Alt + Insert -> stop/start output (same as ^S/^Q)
+ * Alt + Up -> Scroll back console (if implemented)
+ * Alt + Down -> Scroll forward console (if implemented)
+ * Alt + CapsLock -> NumLock
+ *
+ * ++Andreas:
+ *
+ * - Help mapped to K_HELP
+ * - Undo mapped to K_UNDO (= K_F246)
+ * - Keypad Left/Right Parenthesis mapped to new K_PPAREN[LR]
