27 This driver implements support for Infineon Multi-phase XDPE112 and XDPE122
28 family dual loop voltage regulators.
29 These families include XDPE11280, XDPE12284 and XDPE12254 devices.
30 The devices from this family compliant with:
32 - Intel VR13 and VR13HC rev 1.3, IMVP8 rev 1.2 and IMPVP9 rev 1.3 DC-DC
33 converter specification.
34 - Intel SVID rev 1.9. protocol.
35 - PMBus rev 1.3 interface.
37 Devices support linear format for reading input voltage, input and output current,
38 input and output power and temperature.
39 Device supports VID format for reading output voltage. The below modes are
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.
46 Devices support two pages for telemetry.
48 The driver provides for current: input, maximum and critical thresholds
49 and maximum and critical alarms. Critical thresholds and critical alarm are
50 supported only for current output.
51 The driver exports the following attributes for via the sysfs files, where
52 indexes 1, 2 are for "iin" and 3, 4 for "iout":
56 **curr[3-4]_crit_alarm**
64 **curr[1-4]_max_alarm**
66 The driver provides for voltage: input, critical and low critical thresholds
67 and critical and low critical alarms.
68 The driver exports the following attributes for via the sysfs files, where
69 indexes 1, 2 are for "vin" and 3, 4 for "vout":
81 **in[1-41_lcrit_alarm**
83 The driver provides for power: input and alarms. Power alarm is supported only
85 The driver exports the following attributes for via the sysfs files, where
86 indexes 1, 2 are for "pin" and 3, 4 for "pout":
94 The driver provides for temperature: input, maximum and critical thresholds
95 and maximum and critical alarms.
96 The driver exports the following attributes for via the sysfs files:
100 **temp[1-2]_crit_alarm**
106 **temp[1-2]_max_alarm**
