Hi Guenter, I am using "pmbus/ltc2978.c" to use ltc3880 (http://cds.linear.com/docs/en/datasheet/3880fa.pdf) I wanted to configure VOUT_COMMAND (0x21, nominal output voltage set point) to adjust supply voltage per device. VOUT_COMMAND is not exposed to sysfs for the right reasons, such as hwmon/pmbus subsystem is for mainly monitoring not commanding; moreover, to avoid error-prone operations to critical configurations. And I've read Documentation/hwmon/sysfs-interface recommendation. So instead of adding it to sysfs, I take a different direction and I've made a change within ltc2978.c to accommodate my need as follows: - add miscdevice to ltc2978 - use ioctl to configure VOUT_COMMAND A quick prototype works fine, and before I proceed any further, I want to ask your inputs and suggestions on this directions. A patch sending out should be a next step, once I get your input. Please let me know what you think, Thank you, Regards, Insop Song _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
