2011-07-28hwmon: (pmbus) Move PMBus drivers to drivers/hwmon/pmbusGuenter Roeck1-210/+0
Since the number of PMBus drivers is getting large, move them into directory drivers/hwmon/pmbus to improve readability and scalability. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com> Reviewed-by: Robert Coulson <robert.coulson@ericsson.com>
2011-07-10hwmon: (pmbus) Improve auto-detection of temperature status registerGuenter Roeck1-5/+6
It is possible that a PMBus device supports the READ_TEMPERATURE2 and/or READ_TEMPERATURE3 registers but does not support READ_TEMPERATURE1. Improve temperature status register detection to address this condition.
