+Kernel driver xdpe122
+=====================
+
+Supported chips:
+
+  * Infineon XDPE12254
+
+    Prefix: 'xdpe12254'
+
+  * Infineon XDPE12284
+
+    Prefix: 'xdpe12284'

+Description
+-----------
+
+This driver implements support for Infineon Multi-phase XDPE122 family
+dual loop voltage regulators.
+The family includes XDPE12284 and XDPE12254 devices.
+The devices from this family complaint with:
+- Intel VR13 and VR13HC rev 1.3, IMVP8 rev 1.2 and IMPVP9 rev 1.3 DC-DC
+  converter specification.
+- Intel SVID rev 1.9. protocol.
+- PMBus rev 1.3 interface.
+
+Devices support linear format for reading input voltage, input and output current,
+input and output power and temperature.
+Device supports VID format for reading output voltage. The below modes are
+supported:
+- VR12.0 mode, 5-mV DAC - 0x01.
+- VR12.5 mode, 10-mV DAC - 0x02.
+- IMVP9 mode, 5-mV DAC - 0x03.
+- AMD mode 6.25mV - 0x10.
+
+Devices support two pages for telemetry.
+
+The driver provides for current: input, maximum and critical thresholds
+and maximum and critical alarms. Critical thresholds and critical alarm are
+supported only for current output.
+The driver exports the following attributes for via the sysfs files, where
+indexes 1, 2 are for "iin" and 3, 4 for "iout":
+
+**curr[3-4]_crit**
+
+**curr[3-4]_crit_alarm**
+
+**curr[1-4]_input**
+
+**curr[1-4]_label**
+
+**curr[1-4]_max**
+
+**curr[1-4]_max_alarm**
+
+The driver provides for voltage: input, critical and low critical thresholds
+and critical and low critical alarms.
+The driver exports the following attributes for via the sysfs files, where
+indexes 1, 2 are for "vin" and 3, 4 for "vout":
+
+**in[1-4]_crit**
+
+**in[1-4_crit_alarm**
+
+**in[1-4]_input**
+
+**in[1-4_label**
+
+**in[1-4]_lcrit**
+
+**in[1-41_lcrit_alarm**
+
+The driver provides for power: input and alarms. Power alarm is supported only
+for power input.
+The driver exports the following attributes for via the sysfs files, where
+indexes 1, 2 are for "pin" and 3, 4 for "pout":
+
+**power[1-2]_alarm**
+
+**power[1-4]_input**
+
+**power[1-4]_label**
+
+The driver provides for temperature: input, maximum and critical thresholds
+and maximum and critical alarms.
+The driver exports the following attributes for via the sysfs files:
+
+**temp[1-2]_crit**
+
+**temp[1-2]_crit_alarm**
+
+**temp[1-2]_input**
+
+**temp[1-2]_max**
+
+**temp[1-2]_max_alarm**
