| 33 | Description | |
| 34 | ----------- | |
| 35 | ||
| 36 | PXE1610/PXE1110 are Multi-rail/Multiphase Digital Controllers | |
| 37 | and compliant to | |
| 899df7b4 MCC |
38 | |
| 39 | - Intel VR13 DC-DC converter specifications. | |
| 40 | - Intel SVID protocol. | |
| 41 | ||
| 37ab3564 | 42 | Used for Vcore power regulation for Intel VR13 based microprocessors |

| 46 | PXM1310 is a Multi-rail Controller and it is compliant to | |
| 899df7b4 MCC |
47 | |
| 48 | - Intel VR13 DC-DC converter specifications. | |
| 49 | - Intel SVID protocol. | |
| 50 | ||
| 37ab3564 VK |
51 | Used for DDR3/DDR4 Memory power regulation for Intel VR13 and |
| 52 | IMVP8 based systems | |
| 53 | ||

| 55 | Usage Notes | |
| 56 | ----------- | |
| 57 | ||
| 58 | This driver does not probe for PMBus devices. You will have | |
| 59 | to instantiate devices explicitly. | |
| 60 | ||
| 61 | Example: the following commands will load the driver for an PXE1610 | |
| 899df7b4 | 62 | at address 0x70 on I2C bus #4:: |
| 37ab3564 | 63 | |
| 899df7b4 MCC |
64 | # modprobe pxe1610 |
| 65 | # echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device | |

66 | |
| 67 | It can also be instantiated by declaring in device tree | |
