- 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.
