From: Maxim Sloyko <maxims@google.com>
Add the pmbus driver for the Infineon ir38064 voltage regulator.
VOUT_MODE is not supported by the device. The driver fakes linear16
mode with exponent value -8.
The device supports VOUT_PEAK, IOUT_PEAK, and TEMPERATURE_PEAK, however
this driver does not enable them.

v3:
- Updated commit message to indicate behaviors.
v2:
- Cleaned up weird tabbing behavior in doc.
v1:
- Initial patchset.

+Description
+-----------
+
+IR38064 is a Single-input Voltage, Synchronous Buck Regulator, DC-DC Converter.
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.

I meant to add this into the driver as comment (where people can see it
going forward). Never mind, I'll apply the patch and add it myself.
