- 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
