Description
-----------
-Intersil ISL68137 is a digital output 7-phase configurable PWM
-controller with an AVSBus interface.
+This driver supports the Renesas ISL68137 and all 2nd generation Renesas
+digital multiphase voltage regulators (raa_dmpvr2). The ISL68137 is a digital
+output 7-phase configurable PWM controller with an AVSBus interface. 2nd
+generation devices are grouped into 4 distinct configurations: '1rail' for
+single-rail devices, '2rail' for dual-rail devices, '3rail' for 3-rail devices,
+and 'hv' for high voltage single-rail devices. Consult the individual datasheets
+for more information.
