 Description
 -----------
 
-This driver supprts hardware monitoring for Analog Devices ADP1050 Digital
-Controller for Isolated Power Supply with PMBus interface.
+This driver supports hardware monitoring for Analog Devices ADP1050, ADP1051, and
+ADP1055 Digital Controller for Isolated Power Supply with PMBus interface.
 
-The ADP1050 is an advanced digital controller with a PMBus™
+The ADP105X is an advanced digital controller with a PMBus™
 interface targeting high density, high efficiency dc-to-dc power
 conversion used to monitor system temperatures, voltages and currents.
 Through the PMBus interface, the device can monitor input/output voltages,
