Author: Vijay Khemka <vijaykhemka@fb.com> Description ----------- PXE1610/PXE1110 are Multi-rail/Multiphase Digital Controllers and compliant to - Intel VR13 DC-DC converter specifications. - Intel SVID protocol. Used for Vcore power regulation for Intel VR13 based microprocessors - Servers, Workstations, and High-end desktops PXM1310 is a Multi-rail Controller and it is compliant to - Intel VR13 DC-DC converter specifications. - Intel SVID protocol. Used for DDR3/DDR4 Memory power regulation for Intel VR13 and IMVP8 based systems Usage Notes ----------- This driver does not probe for PMBus devices. You will have to instantiate devices explicitly. Example: the following commands will load the driver for an PXE1610 at address 0x70 on I2C bus #4:: # modprobe pxe1610 # echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device It can also be instantiated by declaring in device tree Sysfs attributes ---------------- ====================== ==================================== curr1_label "iin" curr1_input Measured input current curr1_alarm Current high alarm curr[2-4]_label "iout[1-3]" curr[2-4]_input Measured output current curr[2-4]_crit Critical maximum current curr[2-4]_crit_alarm Current critical high alarm in1_label "vin" in1_input Measured input voltage in1_crit Critical maximum input voltage in1_crit_alarm Input voltage critical high alarm in[2-4]_label "vout[1-3]" in[2-4]_input Measured output voltage in[2-4]_lcrit Critical minimum output voltage in[2-4]_lcrit_alarm Output voltage critical low alarm in[2-4]_crit Critical maximum output voltage in[2-4]_crit_alarm Output voltage critical high alarm power1_label "pin" power1_input Measured input power power1_alarm Input power high alarm power[2-4]_label "pout[1-3]" power[2-4]_input Measured output power temp[1-3]_input Measured temperature temp[1-3]_crit Critical high temperature temp[1-3]_crit_alarm Chip temperature critical high alarm temp[1-3]_max Maximum temperature temp[1-3]_max_alarm Chip temperature high alarm ====================== ==================================== |
