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
|
|
|
|
