- Kernel driver adm1275
- =====================
- Supported chips:
- * Analog Devices ADM1275
- Prefix: 'adm1275'
- Addresses scanned: -
- Datasheet: www.analog.com/static/imported-files/data_sheets/ADM1275.pdf
- Author: Guenter Roeck <guenter.roeck@ericsson.com>
- Description
- -----------
- This driver supports hardware montoring for Analog Devices ADM1275 Hot-Swap
- Controller and Digital Power Monitor.
- The ADM1275 is a hot-swap controller that allows a circuit board to be removed
- from or inserted into a live backplane. It also features 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 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 for
- details.
- Platform data support
- ---------------------
- The driver supports standard PMBus driver platform data. Please see
- Documentation/hwmon/pmbus for details.
- Sysfs entries
- -------------
- The following attributes are supported. Limits are read-write; all other
- attributes are read-only.
- in1_label "vin1" or "vout1" depending on chip variant and
- configuration.
- in1_input Measured voltage. From READ_VOUT register.
- in1_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
- in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
- in1_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
- in1_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
- curr1_label "iout1"
- curr1_input Measured current. From READ_IOUT register.
- curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
- curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT register.
