+Description
+-----------
+
+This driver implements support for Intel Common Redundant Power supply with
+PMBus support.
+
+The driver is a client driver to the core PMBus driver.
+Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
+
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
+details.

+
+PMBus may come up with a variety of write protection configuration.
+'pmbus_core.wp' may be used if a particular write protection is necessary.
+The ability to actually alter the protection may also depend on the chip
+so the actual runtime write protection configuration may differ from
+the requested one. pmbus_core currently support the following value:
+
+* 0: write protection removed.
+* 1: Disable all writes except to the WRITE_PROTECT, OPERATION,
+  PAGE, ON_OFF_CONFIG and VOUT_COMMAND commands.
+* 2: Disable all writes except to the WRITE_PROTECT, OPERATION and
+  PAGE commands.
+* 3: Disable all writes except to the WRITE_PROTECT command. Note that
+  protection should include the PAGE register. This may be problematic
+  for multi-page chips, if the chips strictly follows the PMBus
+  specification, preventing the chip from changing the active page.
