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
