2006-08-26[PATCH] hwmon: abituguru timeout fixesHans de Goede
This patch contains 2 sets of fixes for the abituguru: 1) Much improved timeout handling, drasticly reducing the amount of timeout errors on some motherboards 2) Fix the exit paths in the bank1 sensor type detect code to always restore the original settings even on an error. Without this our special test settings could remain seriously confusing the system BIOS's setup menu. Both are very much related and are must haves, to avoid messing up the uguru CMOS settings. Detailed changes: - Much improved timeout / wait for status handling. Many thanks to Sunil Kumar, for all his testing, ideas and patches! The code now first busy waits, polling the uguru for the expected status as this usually succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn in timeout conditions, the amount of busy waiting has been halved from previous versions (120 tries instead of 250). This is not a problem, because this version goes to sleep after 120 attemps for 1 jiffy and then tries again, it does this sleep and try again 5 times before finally giving up. This (almost?) completly removes the timeout errors some people have seen regulary. Apparently some older uguru versions sometimes are distracted for a (relatively) long time. This solves this. - These timeout errors not only occur in the sending address part of reading the uguru but also in the wait for read state, so errors in this state are now handled as retryable just like send address state errors and are only logged and reported to userspace if 3 executive tries fail. - Fix a very nasty bug in the bank1 sensor type detection code, where it would not restore the original settings in any of the error paths! - Since not successfully restoring the original settings can seriously confuse the system BIOS (hang when entering the relevant setup menu), we now try restoring them 3 times before giving up.

2006-07-12[PATCH] hwmon: Fix for first generation Abit uGuru chipsHans de Goede
Now that the abituguru driver is seeing some more widespread testing it has turned out that one the first generation of Abit uGuru motherboards, with uGuru revision 1, the autodetect bank1 sensor type code doesn't (always) work. This patch adds a module param to override the autodetect, and it adds validity checks for the value of the 2 other autodetection override module params. An example of howto use the new param can be found here: http://lm-sensors.org/wiki/Configurations/Abit/AN7 Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-06-22[PATCH] lm70: New hardware monitoring driverKaiwan N Billimoria
This driver implements support for the National Semiconductor LM70 temperature sensor. The LM70 temperature sensor chip supports a single temperature sensor. It communicates with a host processor (or microcontroller) via an SPI/Microwire Bus interface. Communication with the LM70 is simple: when the temperature is to be sensed, the driver accesses the LM70 using SPI communication: 16 SCLK cycles comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's complement digital temperature (sent via the SIO line), is available in the driver for interpretation. This driver makes use of the kernel's in-core SPI support.

This reverts the mutex conversion that was recently done to the hdaps driver; this coversion was buggy because the hdaps driver started using this semaphore in IRQ context, which mutexes do not allow.

This fixes bug #5889, although it doesn't address the whole class of problems. We'd need the ability to blacklist arbitrary I2C addresses on systems known to contain I2C devices which behave badly when probed. Plan the I2C interface for removal as well.
