     20Description
     21-----------
     22
     23This driver implements support for Infineon Digital Multi-phase Controller
     24XDPE152C4 and XDPE15284 dual loop voltage regulators.
     25The 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
     32Devices support linear format for reading input and output voltage, input
     33and output current, input and output power and temperature.
     34
     35Devices support two pages for telemetry.
     36
     37The driver provides for current: input, maximum and critical thresholds
     38and maximum and critical alarms. Low Critical thresholds and Low critical alarm are
     39supported only for current output.
     40The driver exports the following attributes for via the sysfs files, where
     41indexes 1, 2 are for "iin" and 3, 4 for "iout":
     42
     43**curr[1-4]_crit**
     44
     45**curr[1-4]_crit_alarm**
     46
     47**curr[1-4]_input**
     48
     49**curr[1-4]_label**
     50
     51**curr[1-4]_max**
     52
     53**curr[1-4]_max_alarm**
     54
     55**curr[3-4]_lcrit**
     56
     57**curr[3-4]_lcrit_alarm**
     58
     59**curr[3-4]_rated_max**
     60
     61The driver provides for voltage: input, critical and low critical thresholds
     62and critical and low critical alarms.
     63The driver exports the following attributes for via the sysfs files, where
     64indexes 1, 2 are for "vin" and 3, 4 for "vout":
     65
     66**in[1-4]_min**

     89
     90**in[3-4]_rated_min**
     91
     92The driver provides for power: input and alarms.
     93The driver exports the following attributes for via the sysfs files, where
     94indexes 1, 2 are for "pin" and 3, 4 for "pout":
     95
     96**power[1-2]_alarm**
     97
     98**power[1-4]_input**
     99

    101
    102**power[1-4]_max**
    103
    104**power[1-4]_rated_max**
    105
    106The driver provides for temperature: input, maximum and critical thresholds
    107and maximum and critical alarms.
    108The driver exports the following attributes for via the sysfs files:
    109
    110**temp[1-2]_crit**
