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.
