Prev: 2.6.32.1 kernel unable to use more than 2 of 16 CPUs on Intel E5540 (i7)
Next: [PATCH v3 4/4] hwmon: Update MAINTAINERS for smm665 driver
From: Guenter Roeck on 24 Jun 2010 18:10 This patchset adds support for the monitoring features of the Summit Microelectronics SMM665 Six-Channel Active DC Output Controller/Monitor. ------ v2 changes: - Added (untested) support for SMM465, SMM764, and SMM766. - Added vref module parameter to support non-default values of VREF_ADC. - Added an explanation describing what the chip does with _min and _max limit values. - Removed alarm sysfs files (since the chip does not report alarm status in a register, alarm detection was implemented by comparing limits with ADC readings, which can as well be done in userland). - Replaced register enums with defines. - Made limit variable names better readable. - Removed retries from smm665_read_adc(). - Check error reply from i2c_smbus_read_byte_data() and only accept ENXIO when expecting NACK. - Explained reason for byte swap after reading ADC registers in some more detail. - Added debug messages to display the error reason when reading ADC registers failed. v3 changes: - Return error codes from smm665_read_adc(). - Abort after first error in smm665_update_device() and return error code. - Return ADC read errors to user. - Added inX_lcrit and inX_crit attributes for min/max critical voltages. - Added tempX_lcrit attribute for critical low temperature. - Updated sysfs-interface to document support for new attributes. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
