From bc769ff8f5f6e3d249bfde082653e5bf1c2b5698 Mon Sep 17 00:00:00 2001 From: "bgardner@wabtec.com" Date: Tue, 12 Jul 2005 13:21:11 -0500 Subject: [PATCH] I2C: simplify max6875 driver This is an update to the max6875 driver. It no longer does any detection, so the address must be forced on module load. It only makes available the user EEPROM (read-only). This patch is based off 2.6.13-rc2-mm2.

For example, for address 0x50, it also reserves 0x51. +The even-address instance is called 'max6875', the odd one is 'max6875-dummy'. + + +Programming the chip using i2c-dev +---------------------------------- + +Use the i2c-dev interface to access and program the chips. +Reads and write 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. -- cgit v1.2.3 From a8decc658a8800e61f13b9240125f2a34d7fd3f5 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 27 Jul 2005 12:43:03 -0500 Subject: [PATCH] I2C: fix max6875 build error Signed-off-by: Greg Kroah-Hartman --- drivers/i2c/chips/max6875.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/i2c/chips/max6875.c b/drivers/i2c/chips/max6875.c index 4d4ace4b805..1a7993e6354 100644 --- a/drivers/i2c/chips/max6875.c +++ b/drivers/i2c/chips/max6875.c @@ -93,8 +93,7 @@ static void max6875_update_slice(struct i2c_client *client, int slice) if (!(data->valid & (1 << slice)) || time_after(jiffies, data->last_updated[slice])) { - dev_dbg(&client->dev, "Starting update of slice %u\n", - slice, blk->base); + dev_dbg(&client->dev, "Starting update of slice %u\n", slice); data->valid &= ~(1 << slice); -- cgit v1.2.3 From 5033017c2678df9dc75be0139f19701ff224a498 Mon Sep 17 00:00:00 2001 From: Hans-Frieder Vogt Date: Sat, 23 Jul 2005 15:33:39 +0200 Subject: [PATCH] I2C: cleanup of i2c-nforce2 attached is a small patch that removes unused code from i2c-nforce2 and adds a single debug message.

The isa i2c_adapter is no more registered with i2c-core, drivers have to explicitely connect to it using the new i2c_isa_{add,del}_driver interface. At this point, all ISA chip drivers are useless, because they still register with i2c-core in the hope i2c-isa is registered there as well, but it isn't anymore. The fake bus will be named i2c-9191 in sysfs. This is the number it already had internally in various places, so it's not exactly new, except that now the number is seen in userspace as well. This shouldn't be a problem until someone really has 9192 I2C busses in a given system ;) The fake bus will no more show in "i2cdetect -l", as it won't be seen by i2c-dev anymore (not being registered with i2c-core), which is a good thing, as i2cdetect/i2cdump/i2cset cannot operate on this fake bus anyway.

As a result, CONFIG_I2C_ISA doesn't need to be left visible to the user. The good thing here is that users will stop complaining that some driver doesn't work just because they forgot to compile or load i2c-isa. At this point, all drivers are working again and the cleanup phase can begin.

The net effect is that address lists won't be handled anymore, but they were mostly useless in the ISA case anyway (pc87360, smsc47m1, smsc47b397 had already dropped them). We don't need to handle multiple devices, all we may need is a way to force a given address instead of the original one (some drivers already do: sis5595, via686a, w83627hf), and, for drivers supporting multiple chips, a way to force one given kind. All this may be added later on demand, but I actually don't think there will be much demand.

This is one major step in the directiom of merging i2c_probe and i2c_detect. The last obstacle I can think of is the different way forced addresses work between sensors and non-sensors i2c drivers.

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. +  - 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#.

Note that this change will slightly increase the size of the drivers using I2C_CLIENT_INSMOD, with no immediate benefit. This is a requirement if we want to merge i2c_probe and i2c_detect though, and seems a reasonable price to pay in comparison with the previous cleanups which saved much more than that (such as the i2c-isa cleanup or the i2c address ranges removal.)

It defines a structure (i2c_force_data) to associate a module parameter with a given kind value, but in fact this kind value is always the index of the structure in each array it is used in. So this additional value can be omitted, and still be deduced in the code handling these arrays.

It's only an extension of what i2c.h offers, and this extension is not sensors-specific. As a matter of fact, a few non-sensors drivers use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h altogether.

This is in no way related to i2c, so it doesn't belong there. Move the code to hwmon, where it belongs. Note that not all hardware monitoring drivers do VRM/VRD/VID operations, so less drivers depend on hwmon-vid than there were depending on i2c-sensor.

Uninlining it should cause little performance loss if any, and saves a signficant space as well as compilation time.

Note that this slightly changes the way the module parameters are handled. This shouldn't change anything for the most common cases though. For one thing, the function now respects the order of the parameters for address probing. It used to always do lower addresses first. The new approach gives the user more control. For another, ignore addresses don't overrule probe addresses anymore. This could have been restored the way it was at the cost of a few more lines of code, but I don't think it's worth it. Both lists are given as module parameters, so a user would be quite silly to specify the same addresses in both lists. The normal addresses list is the only one that isn't controlled by a module parameter, thus is the only one the user may reasonably want to remove an address from. Another significant change is the fact that i2c_probe() will no more stop when a detection function returns -ENODEV. Just because a driver found a chip it doesn't support isn't a valid reason to stop all probings for this one driver. This closes the long standing lm_sensors ticket #1807. http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1807 I updated the documentation accordingly. In terms of algorithmic complexity, the new code is way better. If I is the ignore address count, P the probe address count, N the normal address count and F the force address count, the old code was doing 128 * (F + I + P + N) iterations max, while the new code does F + P + ((I+1) * N) iterations max. For the most common case where F, I and P are empty, this is down from 128 * N to N.

This did happen already. * As additional probing addresses can be passed to most i2c chip drivers as module parameters, virtually every i2c chip driver would need the protection if we want to be really safe. * Why duplicate code when we can easily avoid it?

However, it happens that several drivers were using I2C_ALGO_* for adapter ids, so we need to correct these before we can get rid of all the I2C_ALGO_* definitions. Note that this also fixes a bug in media/video/tvaudio.c: /* don't attach on saa7146 based cards, because dedicated drivers are used */ if ((adap->id & I2C_ALGO_SAA7146)) return 0; This test was plain broken, as it would succeed for many more adapters than just the saa7146: any those id would share at least one bit with the saa7146 id.

The cause of the incompatibility has gone since [2], so I think we can get rid of them, as they tend to make the code harder to read and longer to preprocess/compile for no more benefit. I'd hope nobody seriously attempts to keep media/video driver compatible across Linux trees anymore, BTW.

This can be done in userspace with the i2cdetect tool (part of the lm_sensors package) instead. What's more, i2cdetect gives more control on the way the bus is scanned, and is safer (i2c-keywest currently scans reserved addresses and doesn't properly handle the famous 24RF08 corruption case.) Thus, I would propose that this module parameter be simply dropped.

The declarative skew is clearer, less error-prone, and more efficient. The use of 11+offset-4 below reflects the fact that the sysfs numbering of these units is 4, 5, 6, but they use internal VLM units 11, 12, 13 to measure the thermistor voltages. There's one remaining skew factor, in *_crit callbacks below, because there are no critical thresholds for voltages 0-10, only for those supporting the thermistors.
