| * hwmon: (f71882fg) Separate max and crit alarm and beepHans de Goede2009-01-07
| | | | | | | | | | | | | | | | | | | | | | | | While studying the datasheets for adding F8000 support, I noticed that the F718x2 has separate alarms (and beep control) for its max and crit limits. We keep the temp#_alarm attributes as they are, even though it would be more logical to rename them to temp#_max_alarm. Because lm_sensors v2 depends on them.

| * hwmon: (f71882fg) Check for hwmon powerdown stateHans de Goede2009-01-07
| | | | | | | | | | | | | | | | | | | | More F8000 prep work. Take over the checking if the hwmon part is not powered down from the standalone f8000 driver. This check is valid for all supported models. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * hwmon: (f71882fg) Cleanup fan and temp hyst functionsHans de Goede2009-01-07
| | | | | | | | | | | | | | | | | | | | Simplify fan and temp hyst. handling by treating the registers as an array of nibbles instead of using switch cases. Also unify the way hysts are handled between temp and fans, the temp code was storing the actual per temp hyst values in 4 u8's, where as the fan code was storing actual register values.

| * hwmon: (f71882fg) Fix various sysfs callback function issuesHans de Goede2009-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While working on adding F8000 support I noticed that various of the store sysfs functions (and a few of the show also) had issues. This patch fixes the following issues in these functions: * store: storing the result of strto[u]l in an int, resulting in a possible overflow before boundary checking * store: use of f71882fg_update_device(), we don't want to read the whole device in store functions, just the registers we need * store: use of cached register values instead of reading the needed regs in the store function, including cases where f71882fg_update_device() was not used, this could cause real isues * show: shown value is a calculation of 2 or more cached register reads, without locking the data struct.

| * hwmon: (f71882fg) Prepare for adding F8000 supportHans de Goede2009-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a preparation patch for adding F8000 support to the f71882fg driver. If you look at the register addresses and esp, the bits used for the temperature channels, then you will notice that it appears that they start at 1 in a system meant to start at 0. As the F8000 actually uses the 0 addresses and bits, this patch changes the f71882fg driver to take 4 temperatures numbered 0-3 in to account, using 1-3 in this new scheme for the temperatures actually present in the F718x2FG.

| | | | | | | | | | | | | | | | | | | | | | | | It turns out that the adt7470's automatic fan control algorithm only works when the temperature sensors get updated. This in turn happens only when someone tells the chip to read its temperature sensors. Regrettably, this means that we have to drive the chip periodically. Signed-off-by: Darrick J.

| | | | | | | | | | | | | | | | | | | | | | | | | | The adt7470 driver currently assumes that 1s is the proper time to wait to read all temperature sensors. However, the correct time is 200ms * number_of_sensors. This patch sets the default time to provide for 10 sensors and then lowers it based on the number of sensor inputs that have nozero values.

* | adt7470: fix pwm at a certain level during temperature sensor scanDarrick J. Wong2009-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the small window that it takes to read the temperature sensors, the pwm outputs momentarily drop to 0. This causes a noticeable hiccup in fan speed, which is slightly annoying. The solution is to manually program the pwm output with whatever the automatic value is and then shift the fans to manual control while reading temperatures. Once that is done, put the fans back to whatever mode of control was there before. Signed-off-by: Darrick J.

* LIS3LV02Dx Accelerometer driverPavel Machek2008-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | This adds a driver to the accelerometer sensor found in several HP laptops (under the commercial names of "HP Mobile Data Protection System 3D" and "HP 3D driveguard"). It tries to have more or less the same interfaces as the hdaps and other accelerometer drivers: in sysfs and as a joystick. This driver was first written by Yan Burman. Eric Piel has updated it and slimed it up (including the removal of an interface to access to the free-fall feature of the sensor because it is not reliable enough for now). Pavel Machek removed few more features and switched locking from semaphore to mutex. Several people have contributed to the database of the axes.

* hwmon: (lm90) Fix handling of hysteresis valueJean Delvare2008-10-26
| | | | | | | | | | | | | | | | | | | | | | | There are several problems in the way the hysteresis value is handled by the lm90 driver: * In show_temphyst(), specific handling of the MAX6646 is missing, so the hysteresis is reported incorrectly if the critical temperature is over 127 degrees C. * In set_temphyst(), the new hysteresis register value is written to the chip but data->temp_hyst isn't updated accordingly, so there is a short period of time (up to 2 seconds) where the old hystereris value will be returned while the new one is already active. * In set_temphyst(), the critical temperature which is used as a base to compute the value of the hysteresis register lacks device-specific handling. As a result, the value of the hysteresis register might be incorrect for the ADT7461 and MAX6646 chips. Fix these 3 bugs.

* hwmon: applesmc: lighter wait mechanism, drastic improvementHenrik Rydberg2008-10-20
| | | | | | | | | | | | | | | | | | | The read fail ratio is sensitive to the delay between the first byte written and the first byte read; apparently the sensors cannot be rushed. Increasing the minimum wait time, without changing the total wait time, improves the fail ratio from a 8% chance that any of the sensors fails in one read, down to 0.4%, on a Macbook Air. On a Macbook Pro 3,1, the effect is even more apparent. By reducing the number of status polls, the ratio is further improved to below 0.1%. Finally, increasing the total wait time brings the fail ratio down to virtually zero.

| | | | | | | | | | | | | | On some recent Macbooks, the package length for the light sensors ALV0 and ALV1 has changed from 6 to 10. This patch allows for a variable package length encompassing both variants.

* hwmon: applesmc: prolong status waitHenrik Rydberg2008-10-20
| | | | | | | | | | | | | | | | | The time to wait for a status change while reading or writing to the SMC ports is a balance between read reliability and system performance. The current setting yields rougly three errors in a thousand when simultaneously reading three different temperature values on a Macbook Air. This patch increases the setting to a value yielding roughly one error in ten thousand, with no noticable system performance degradation.
