+Description
+-----------
+
+PXE1610 is a Multi-rail/Multiphase Digital Controllers and
+it is compliant to Intel VR13 DC-DC converter specifications.
+
+
+Usage Notes
+-----------
+
+This driver can be enabled with kernel config CONFIG_SENSORS_PXE1610
+set to 'y' or 'm'(for module).
+
+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 if it is
+built as a kernel not as a module.
