| 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 |
