SPDX-License-Identifier: GPL-2.0-or-later Kernel driver ltc4286 ===================== Supported chips: * Analog Devices LTC4286 Prefix: 'ltc4286' Addresses scanned: - Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ltc4286.pdf * Analog Devices LTC4287 Prefix: 'ltc4287' Addresses scanned: - Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ltc4287.pdf Author: Delphine CC Chiu <Delphine_CC_Chiu@Wiwynn.com> Description ----------- This driver supports hardware monitoring for Analog Devices LTC4286 and LTC4287 Hot-Swap Controller and Digital Power Monitors. LTC4286 and LTC4287 are hot-swap controllers that allow a circuit board to be removed from or inserted into a live backplane. They also feature current and voltage readback via an integrated 12 bit analog-to-digital converter (ADC), accessed using a PMBus interface. The driver is a client driver to the core PMBus driver. Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. Usage Notes ----------- This driver does not auto-detect devices. You will have to instantiate the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for details. The shunt value in micro-ohms can be set via device tree at compile-time. Please refer to the Documentation/devicetree/bindings/hwmon/lltc,ltc4286.yaml for bindings if the device tree is used. Platform data support --------------------- The driver supports standard PMBus driver platform data. Please see Documentation/hwmon/pmbus.rst for details. Sysfs entries ------------- The following attributes are supported. Limits are read-write, history reset attributes are write-only, all other attributes are read-only. ======================= ======================================================= in1_label "vin" in1_input Measured voltage. in1_alarm Input voltage alarm. in1_min Minimum input voltage. in1_max Maximum input voltage. in2_label "vout1" in2_input Measured voltage. in2_alarm Output voltage alarm. in2_min Minimum output voltage. in2_max Maximum output voltage. curr1_label "iout1" curr1_input Measured current. curr1_alarm Output current alarm. curr1_max Maximum current. power1_label "pin" power1_input Input power. power1_alarm Input power alarm. power1_max Maximum poewr. temp1_input Chip temperature. temp1_min Minimum chip temperature. temp1_max Maximum chip temperature. temp1_crit Critical chip temperature. temp1_alarm Chip temperature alarm. ======================= ======================================================= |
