20 Description
21 -----------
22
23 This driver implements support for Infineon Di
24 XDPE152C4 and XDPE15284 dual loop voltage regu
25 The devices are compliant with:
26
27 - Intel VR13, VR13HC and VR14 rev 1.86
28 converter specification.
29 - Intel SVID rev 1.93. protocol.
30 - PMBus rev 1.3.1 interface.
31
32 Devices support linear format for reading inpu
33 and output current, input and output power and
34
35 Devices support two pages for telemetry.
36
37 The driver provides for current: input, maximu
38 and maximum and critical alarms. Low Critical
39 supported only for current output.
