+Kernel driver adt7473
+======================
+
+Supported chips:
+ * Analog Devices ADT7473
+ Prefix: 'adt7473'
+ Addresses scanned: I2C 0x2C, 0x2D, 0x2E
+ Datasheet: Publicly available at the Analog Devices website
+
+Author: Darrick J. Wong
+
+Description
+-----------
+
+This driver implements support for the Analog Devices ADT7473 chip family.
+
+The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
+specification. Using an analog to digital converter it measures three (3)
+temperatures and two (2) voltages. It has three (3) 16-bit counters for
+measuring fan speed. There are three (3) PWM outputs that can be used
+to control fan speed.
+
+A sophisticated control system for the PWM outputs is designed into the
+LM85 that allows fan speed to be adjusted automatically based on any of the
+three temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the ADT7473 will adjust the PWM outputs in
+response to the measured temperatures without further host intervention.
+This feature can also be disabled for manual control of the PWM's.
+
+Each of the measured inputs (voltage, temperature, fan speed) has
+corresponding high/low limit values. The ADT7473 will signal an ALARM if
+any measured value exceeds either limit.
+
+The ADT7473 samples all inputs continuously. The driver will not read
+the registers more often than once every other second. Further,
+configuration data is only read once per minute.
+
+Special Features
+----------------
+
+The ADT7473 have a 10-bit ADC and can therefore measure temperatures
+with 0.25 degC resolution. Temperature readings can be configured either
+for twos complement format or "Offset 64" format, wherein 63 is subtracted
+from the raw value to get the temperature value.
+
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+
+Hardware Configurations
+-----------------------
+
+The ADT7473 chips have an optional SMBALERT output that can be used to
+signal the chipset in case a limit is exceeded or the temperature sensors
+fail. Individual sensor interrupts can be masked so they won't trigger
+SMBALERT. The SMBALERT output if configured replaces the PWM2 function.
+
+Configuration Notes
+-------------------
+
+Besides standard interfaces driver adds the following:
+
+* PWM Control
+
+* pwm#_auto_point1_pwm and pwm#_auto_point1_temp and
+* pwm#_auto_point2_pwm and pwm#_auto_point2_temp -
+
+point1: Set the pwm speed at a lower temperature bound.
+point2: Set the pwm speed at a higher temperature bound.
+
+The ADT7473 will scale the pwm between the lower and higher pwm speed when
+the temperature is between the two temperature boundaries. PWM values range
+from 0 (off) to 255 (full speed).
+
+Notes
+-----
+
+The NVIDIA binary driver presents an ADT7473 chip via an on-card i2c bus.
+Unfortunately, they fail to set the i2c adapter class, so this driver may
+fail to find the chip until the nvidia driver is patched.

Multiple Commands, Module Parameters

enable various classes of debugging output, for example:
- modprobe ibm_acpi debug=0xffff
+ modprobe thinkpad_acpi debug=0xffff
will enable all debugging output classes. It takes a bitmask, so
to enable more than one output class, just add their values.

PM_EVENT_SUSPEND -- quiesce the driver and put hardware into a low-power
state. When used with system sleep states like "suspend-to-RAM" or
"standby", the upcoming resume() call will often be able to rely on
- state kept in hardware, or issue system wakeup events. When used
- instead with suspend-to-disk, few devices support this capability;
- most are completely powered off.

+ PM_EVENT_HIBERNATE -- Put hardware into a low-power state and enable wakeup
+ events as appropriate. It is only used with hibernation

PM_EVENT_FREEZE -- quiesce the driver, but don't necessarily change into
any low power mode. A system snapshot is about to be taken, often
wakeup events nor DMA are allowed.
To enter "standby" (ACPI S1) or "Suspend to RAM" (STR, ACPI S3) states, or
-the similarly named APM states, only PM_EVENT_SUSPEND is used; for "Suspend

There's also PM_EVENT_ON, a value which never appears as a suspend event

* - code cleaned of unnecessary rds_commands
* - USB Vendor/Product ID for ADS/Tech FM Radio Receiver verified
* (thanks to Guillaume RAMOUSSE)
+ * 2008-01-27 Tobias Lorenz <tobias.lorenz@gmx.net>
+ * Version 1.0.5
+ * - number of seek_retries changed to tune_timeout
+ * - fixed problem with incomplete tune operations by own buffers
+ * - optimization of variables and printf types
+ * - improved error logging
+ * 2008-01-31 Tobias Lorenz <tobias.lorenz@gmx.net>
+ * Oliver Neukum <oliver@neukum.org>
+ * Version 1.0.6
+ * - fixed coverity checker warnings in *_usb_driver_disconnect
+ * - probe()/open() race by correct ordering in probe()
+ * - DMA coherency rules by separate allocation of all buffers
+ * - use of endianness macros
+ * - abuse of spinlock, replaced by mutex
+ * - racy handling of timer in disconnect,
+ * replaced by delayed_work
+ * - racy interruptible_sleep_on(),
+ * replaced with wait_event_interruptible()
+ * - handle signals in read()
+ * 2008-02-08 Tobias Lorenz <tobias.lorenz@gmx.net>
+ * Oliver Neukum <oliver@neukum.org>
+ * Version 1.0.7
+ * - usb autosuspend support
*
* ToDo:
* - add seeking support

+ * Watchdog driver for SiByte SB1 SoCs
+ *
+ * Copyright (C) 2007 OnStor, Inc. * Andrew Sharp <andy.sharp@onstor.com>
+ *
+ * This driver is intended to make the second of two hardware watchdogs
+ * on the Sibyte 12XX and 11XX SoCs available to the user. There are two
+ * such devices available on the SoC, but it seems that there isn't an
+ * enumeration class for watchdogs in Linux like there is for RTCs.
+ * The second is used rather than the first because it uses IRQ 1,
+ * thereby avoiding all that IRQ 0 problematic nonsense.
+ *
+ * I have not tried this driver on a 1480 processor; it might work
+ * just well enough to really screw things up.
+ *
+ * It is a simple timer, and there is an interrupt that is raised the
+ * first time the timer expires. The second time it expires, the chip
+ * is reset and there is no way to redirect that NMI. Which could
+ * be problematic in some cases where this chip is sitting on the HT
+ * bus and has just taken responsibility for providing a cache block.
+ * Since the reset can't be redirected to the external reset pin, it is
+ * possible that other HT connected processors might hang and not reset.
+ * For Linux, a soft reset would probably be even worse than a hard reset.
+ * There you have it.
+ *
+ * The timer takes 23 bits of a 64 bit register (?) as a count value,
+ * and decrements the count every microsecond, for a max value of
+ * 0x7fffff usec or about 8.3ish seconds.
+ *
+ * This watchdog borrows some user semantics from the softdog driver,
+ * in that if you close the fd, it leaves the watchdog running, unless
+ * you previously wrote a 'V' to the fd, in which case it disables
+ * the watchdog when you close the fd like some other drivers.
+ *
+ * Based on various other watchdog drivers, which are probably all
+ * loosely based on something Alan Cox wrote years ago.

- *
- * c) save areas for each coprocessor and for non-coprocessor
- * ("extra") state

- * Note that save areas may require up to 16-byte alignment when

- * contents are copied to elf_fpregset_t from the active save areas
- * (see 'struct task_struct' definition in processor.h for that)
