+Module Parameters
+-----------------
+
+* init int
+ (default 1)
+ Use 'init=0' to bypass initializing the chip.
+ Try this if your computer crashes when you load the module.
+
+* force_subclients=bus,caddr,saddr,saddr
+ This is used to force the i2c addresses for subclients of
+ a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b'
+ to force the subclients of chip 0x2f on bus 0 to i2c addresses
+ 0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for the Winbond W83792AD/D.
+
+Detection of the chip can sometimes be foiled because it can be in an
+internal state that allows no clean access (Bank with ID register is not
+currently selected). If you know the address of the chip, use a 'force'
+parameter; this will put it into a more well-behaved state first.
+
+The driver implements three temperature sensors, seven fan rotation speed
+sensors, nine voltage sensors, and two automatic fan regulation
+strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II.
+Automatic fan control mode is possible only for fan1-fan3. Fan4-fan7 can run
+synchronized with selected fan (fan1-fan3). This functionality and manual PWM
+control for fan4-fan7 is not yet implemented.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
+the temperature gets higher than the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
+128) to give the readings more range or accuracy.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+Alarms are provided as output from "realtime status register". Following bits
+are defined:
+
+bit - alarm on:
+0 - in0
+1 - in1
+2 - temp1
+3 - temp2
+4 - temp3
+5 - fan1
+6 - fan2
+7 - fan3
+8 - in2
+9 - in3
+10 - in4
+11 - in5
+12 - in6
+13 - VID change
+14 - chassis
+15 - fan7
+16 - tart1
+17 - tart2
+18 - tart3
+19 - in7
+20 - in8
+21 - fan4
+22 - fan5
+23 - fan6
+
+Tart will be asserted while target temperature cannot be achieved after 3 minutes
+of full speed rotation of corresponding fan.
+
+In addition to the alarms described above, there is a CHAS alarm on the chips
+which triggers if your computer case is open (This one is latched, contrary
+to realtime alarms).
+
+The chips only update values each 3 seconds; reading them more often will
+do no harm, but will return 'old' values.
+
+
+W83792D PROBLEMS
+----------------
+Known problems:
+ - This driver is only for Winbond W83792D C version device, there
+ are also some motherboards with B version W83792D device. The
+ calculation method to in6-in7(measured value, limits) is a little
+ different between C and B version. C or B version can be identified
+ by CR[0x49h].
+ - The function of vid and vrm has not been finished, because I'm NOT
+ very familiar with them. Adding support is welcome.
+Â - The function of chassis open detection needs more tests.
+ - If you have ASUS server board and chip was not found: Then you will
+ need to upgrade to latest (or beta) BIOS. If it does not help please
+ contact us.
+
+Fan control
+-----------
+
+Manual mode
+-----------
+
+Works as expected. You just need to specify desired PWM/DC value (fan speed)
+in appropriate pwm# file.
+
+Thermal cruise
+--------------
+
+In this mode, W83792D provides the Smart Fan system to automatically control
+fan speed to keep the temperatures of CPU and the system within specific
+range. At first a wanted temperature and interval must be set. This is done
+via thermal_cruise# file. The tolerance# file serves to create T +- tolerance
+interval. The fan speed will be lowered as long as the current temperature
+remains below the thermal_cruise# +- tolerance# value. Once the temperature
+exceeds the high limit (T+tolerance), the fan will be turned on with a
+specific speed set by pwm# and automatically controlled its PWM duty cycle
+with the temperature varying. Three conditions may occur:
+
+(1) If the temperature still exceeds the high limit, PWM duty
+cycle will increase slowly.
+
+(2) If the temperature goes below the high limit, but still above the low
+limit (T-tolerance), the fan speed will be fixed at the current speed because
+the temperature is in the target range.
+
+(3) If the temperature goes below the low limit, PWM duty cycle will decrease
+slowly to 0 or a preset stop value until the temperature exceeds the low
+limit. (The preset stop value handling is not yet implemented in driver)
+
+Smart Fan II
+------------
+
+W83792D also provides a special mode for fan. Four temperature points are
+available. When related temperature sensors detects the temperature in preset
+temperature region (sf2_point@_fan# +- tolerance#) it will cause fans to run
+on programmed value from sf2_level@_fan#. You need to set four temperatures
+for each fan.
+
+
+/sys files
+----------
+
+pwm[1-3] - this file stores PWM duty cycle or DC value (fan speed) in range:
+ 0 (stop) to 255 (full)
+pwm[1-3]_enable - this file controls mode of fan/temperature control:
+ * 0 Disabled
+ * 1 Manual mode
+ * 2 Smart Fan II
+ * 3 Thermal Cruise
+pwm[1-3]_mode - Select PWM of DC mode
+ * 0 DC
+ * 1 PWM
+thermal_cruise[1-3] - Selects the desired temperature for cruise (degC)
+tolerance[1-3] - Value in degrees of Celsius (degC) for +- T
+sf2_point[1-4]_fan[1-3] - four temperature points for each fan for Smart Fan II
+sf2_level[1-3]_fan[1-3] - three PWM/DC levels for each fan for Smart Fan II

Prefix: 'max6875'
- Addresses scanned: 0x50, 0x52
+ Addresses scanned: None (see below)

-Module Parameters
------------------
-
-* allow_write int
- Set to non-zero to enable write permission:
- *0: Read only
- 1: Read and write
-
-
Description
-----------
The Maxim MAX6874 is a similar, mostly compatible device, with more intputs
and outputs:
-
vin gpi vout
MAX6874 6 4 8
MAX6875 4 3 5
-MAX6874 chips can have four different addresses (as opposed to only two for
-the MAX6875). The additional addresses (0x54 and 0x56) are not probed by
-this driver by default, but the probe module parameter can be used if
-needed.
-
-See the datasheet for details on how to program the EEPROM.
+See the datasheet for more information.
Sysfs entries
-------------
-eeprom_user - 512 bytes of user-defined EEPROM space. Only writable if
- allow_write was set and register 0x43 is 0.
-
-eeprom_config - 70 bytes of config EEPROM. Note that changes will not get
- loaded into register space until a power cycle or device reset.
-
-reg_config - 70 bytes of register space. Any changes take affect immediately.
+eeprom - 512 bytes of user-defined EEPROM space.
General Remarks
---------------
-A typical application will require that the EEPROMs be programmed once and
-never altered afterwards.
+Valid addresses for the MAX6875 are 0x50 and 0x52.
+Valid addresses for the MAX6874 are 0x50, 0x52, 0x54 and 0x56.
+The driver does not probe any address, so you must force the address.
+
+Example:
+$ modprobe max6875 force=0,0x50
+
+The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple
+addresses. For example, for address 0x50, it also reserves 0x51.
+The even-address instance is called 'max6875', the odd one is 'max6875 subclient'.
+
+
+Programming the chip using i2c-dev
+----------------------------------
+
+Use the i2c-dev interface to access and program the chips.
+Reads and writes are performed differently depending on the address range.
+
+The configuration registers are at addresses 0x00 - 0x45.
+Use i2c_smbus_write_byte_data() to write a register and
+i2c_smbus_read_byte_data() to read a register.
+The command is the register number.
+
+Examples:
+To write a 1 to register 0x45:
+ i2c_smbus_write_byte_data(fd, 0x45, 1);
+
+To read register 0x45:
+ value = i2c_smbus_read_byte_data(fd, 0x45);
+
+
+The configuration EEPROM is at addresses 0x8000 - 0x8045.
+The user EEPROM is at addresses 0x8100 - 0x82ff.
+
+Use i2c_smbus_write_word_data() to write a byte to EEPROM.
+
+The command is the upper byte of the address: 0x80, 0x81, or 0x82.
+The data word is the lower part of the address or'd with data << 8.
+ cmd = address >> 8;
+ val = (address & 0xff) | (data << 8);
+
+Example:
+To write 0x5a to address 0x8003:
+ i2c_smbus_write_word_data(fd, 0x80, 0x5a03);
+
+
+Reading data from the EEPROM is a little more complicated.
+Use i2c_smbus_write_byte_data() to set the read address and then
+i2c_smbus_read_byte() or i2c_smbus_read_i2c_block_data() to read the data.
+
+Example:
+To read data starting at offset 0x8100, first set the address:
+ i2c_smbus_write_byte_data(fd, 0x81, 0x00);
+
+And then read the data
+ value = i2c_smbus_read_byte(fd);
+
+ or
+
+ count = i2c_smbus_read_i2c_block_data(fd, 0x84, buffer);
+
+The block read should read 16 bytes.
+0x84 is the block read command.
+
+See the datasheet for more details.
If you try to access an adapter from a userspace program, you will have
to use the /dev interface. You will still have to check whether the
functionality you need is supported, of course. This is done using
-the I2C_FUNCS ioctl. An example, adapted from the lm_sensors i2c_detect

You do not have to use this parameter interface; but don't try to use

+function i2c_probe() if you don't.
NOTE: If you want to write a `sensors' driver, the interface is slightly
different! See below.
-Probing classes (i2c)
----------------------
+Probing classes
+---------------
All parameters are given as lists of unsigned 16-bit integers. Lists are
terminated by I2C_CLIENT_END.
ignore: insmod parameter.
A list of pairs. The first value is a bus number (-1 for any I2C bus),
the second is the I2C address. These addresses are never probed.
- This parameter overrules 'normal' and 'probe', but not the 'force' lists.
+ This parameter overrules the 'normal_i2c' list only.
force: insmod parameter.
A list of pairs. The first value is a bus number (-1 for any I2C bus),
the second is the I2C address. A device is blindly assumed to be on
the given address, no probing is done.
+Additionally, kind-specific force lists may optionally be defined if
+the driver supports several chip kinds. They are grouped in a
+NULL-terminated list of pointers named forces, those first element if the
+generic force list mentioned above. Each additional list correspond to an
+insmod parameter of the form force_<kind>.
+
Fortunately, as a module writer, you just have to define the `normal_i2c'
parameter. The complete declaration could look like this:
/* Magic definition of all other variables and things */
I2C_CLIENT_INSMOD;
+ /* Or, if your driver supports, say, 2 kind of devices: */
+ I2C_CLIENT_INSMOD_2(foo, bar);
+
+If you use the multi-kind form, an enum will be defined for you:
+ enum chips { any_chip, foo, bar, ... }
+You can then (and certainly should) use it in the driver code.
Note that you *have* to call the defined variable `normal_i2c',
without any prefix!
-Probing classes (sensors)
--------------------------
-
-If you write a `sensors' driver, you use a slightly different interface.
-As well as I2C addresses, we have to cope with ISA addresses. Also, we
-use a enum of chip types. Don't forget to include `sensors.h'.
-
-The following lists are used internally. They are all lists of integers.
-
- normal_i2c: filled in by the module writer. Terminated by SENSORS_I2C_END.
- A list of I2C addresses which should normally be examined.
- normal_isa: filled in by the module writer. Terminated by SENSORS_ISA_END.
- A list of ISA addresses which should normally be examined.
- probe: insmod parameter. Initialize this list with SENSORS_I2C_END values.
- A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
- the ISA bus, -1 for any I2C bus), the second is the address. These
- addresses are also probed, as if they were in the 'normal' list.
- ignore: insmod parameter. Initialize this list with SENSORS_I2C_END values.
- A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
- the ISA bus, -1 for any I2C bus), the second is the I2C address. These
- addresses are never probed. This parameter overrules 'normal' and
- 'probe', but not the 'force' lists.
-
-Also used is a list of pointers to sensors_force_data structures:
- force_data: insmod parameters. A list, ending with an element of which
- the force field is NULL.
- Each element contains the type of chip and a list of pairs.
- The first value is a bus number (SENSORS_ISA_BUS for the ISA bus,
- -1 for any I2C bus), the second is the address.
- These are automatically translated to insmod variables of the form
- force_foo.
-
-So we have a generic insmod variabled `force', and chip-specific variables
-`force_CHIPNAME'.
-
-Fortunately, as a module writer, you just have to define the `normal_i2c'
-and `normal_isa' parameters, and define what chip names are used.
-The complete declaration could look like this:
- /* Scan i2c addresses 0x37, and 0x48 to 0x4f */
- static unsigned short normal_i2c[] = { 0x37, 0x48, 0x49, 0x4a, 0x4b, 0x4c,
- 0x4d, 0x4e, 0x4f, I2C_CLIENT_END };
- /* Scan ISA address 0x290 */
- static unsigned int normal_isa[] = {0x0290,SENSORS_ISA_END};
-
- /* Define chips foo and bar, as well as all module parameters and things */
- SENSORS_INSMOD_2(foo,bar);
-
-If you have one chip, you use macro SENSORS_INSMOD_1(chip), if you have 2
-you use macro SENSORS_INSMOD_2(chip1,chip2), etc. If you do not want to
-bother with chip types, you can use SENSORS_INSMOD_0.
-
-A enum is automatically defined as follows:
- enum chips { any_chip, chip1, chip2, ... }
-
-
Attaching to an adapter
-----------------------
return i2c_probe(adapter,&addr_data,&foo_detect_client);
}
-For `sensors' drivers, use the i2c_detect function instead:
-
- int foo_attach_adapter(struct i2c_adapter *adapter)
- {
- return i2c_detect(adapter,&addr_data,&foo_detect_client);
- }
-
Remember, structure `addr_data' is defined by the macros explained above,
so you do not have to define it yourself.
-The i2c_probe or i2c_detect function will call the foo_detect_client
+The i2c_probe function will call the foo_detect_client
function only for those i2c addresses that actually have a device on
them (unless a `force' parameter was used). In addition, addresses that
are already in use (by some other registered client) are skipped.
The detect client function
--------------------------
-The detect client function is called by i2c_probe or i2c_detect.
-The `kind' parameter contains 0 if this call is due to a `force'
-parameter, and -1 otherwise (for i2c_detect, it contains 0 if
-this call is due to the generic `force' parameter, and the chip type
-number if it is due to a specific `force' parameter).
+The detect client function is called by i2c_probe. The `kind' parameter
+contains -1 for a probed detection, 0 for a forced detection, or a positive
+number for a forced detection with a chip type forced.
Below, some things are only needed if this is a `sensors' driver. Those
parts are between /* SENSORS ONLY START */ and /* SENSORS ONLY END */
markers.
-This function should only return an error (any value != 0) if there is
-some reason why no more detection should be done anymore. If the
-detection just fails for this address, return 0.
+Returning an error different from -ENODEV in a detect function will cause
+the detection to stop: other addresses and adapters won't be scanned.
+This should only be done on fatal or internal errors, such as a memory
+shortage or i2c_attach_client failing.
For now, you can ignore the `flags' parameter. It is there for future use.
const char *type_name = "";
int is_isa = i2c_is_isa_adapter(adapter);
- if (is_isa) {
+ /* Do this only if the chip can additionally be found on the ISA bus
+ (hybrid chip). */
- /* If this client can't be on the ISA bus at all, we can stop now
- (call `goto ERROR0'). But for kicks, we will assume it is all
- right. */
