24 Description
25 -----------
26
27 This driver implements support for Infineon Mu
28 family dual loop voltage regulators.
29 These families include XDPE11280, XDPE12284 an
30 The devices from this family compliant with:
31
32 - Intel VR13 and VR13HC rev 1.3, IMVP8 rev 1.2
33 converter specification.
34 - Intel SVID rev 1.9. protocol.
35 - PMBus rev 1.3 interface.
36
37 Devices support linear format for reading inpu
38 input and output power and temperature.
39 Device supports VID format for reading output
40 supported:
41 - VR12.0 mode, 5-mV DAC - 0x01.
42 - VR12.5 mode, 10-mV DAC - 0x02.
43 - IMVP9 mode, 5-mV DAC - 0x03.
44 - AMD mode 6.25mV - 0x10.
45
46 Devices support two pages for telemetry.
47
48 The driver provides for current: input, maximu
49 and maximum and critical alarms. Critical thre
50 supported only for current output.
