+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
+
