SPDX-License-Identifier: GPL-2.0 Kernel driver max15301 ====================== Supported chips: * Maxim MAX15301 Prefix: 'max15301', 'bmr461' Addresses scanned: - Datasheet: https://datasheets.maximintegrated.com/en/ds/MAX15301.pdf Author: Erik Rosen <erik.rosen@metormote.com> Description ----------- This driver supports hardware monitoring for Maxim MAX15301 controller chip and compatible modules. The driver is a client driver to the core PMBus driver. Please see Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core 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. Platform data support --------------------- The driver supports standard PMBus driver platform data. Module parameters ----------------- delay ----- The controller requires a minimum interval between I2C bus accesses. The default interval is set to 100 us. For manual override, the driver provides a writeable module parameter, 'delay', which can be used to set the interval to a value between 0 and 65,535 microseconds. Sysfs entries ------------- The following attributes are supported. Limits are read-write; all other attributes are read-only. ======================= ======================================================== in1_label "vin" in1_input Measured input voltage. in1_lcrit Critical minimum input voltage. in1_crit Critical maximum input voltage. in1_lcrit_alarm Input voltage critical low alarm. in1_crit_alarm Input voltage critical high alarm. in2_label "vout1" in2_input Measured output voltage. in2_lcrit Critical minimum output Voltage. in2_crit Critical maximum output voltage. in2_lcrit_alarm Critical output voltage critical low alarm. in2_crit_alarm Critical output voltage critical high alarm. curr1_label "iout1" curr1_input Measured output current. curr1_crit Critical maximum output current. curr1_crit_alarm Output current critical high alarm. temp1_input Measured maximum temperature of all phases. temp1_max Maximum temperature limit. temp1_max_alarm High temperature alarm. temp1_crit Critical maximum temperature limit. temp1_crit_alarm Critical maximum temperature alarm. ======================= ======================================================== |
