22 This driver supports hardware monitoring for Maxim MAX15301 controller chip and
25 The driver is a client driver to the core PMBus driver. Please see
26 Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core for details
27 on PMBus client drivers.
33 This driver does not auto-detect devices. You will have to instantiate the
34 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
41 The driver supports standard PMBus driver platform data.
50 The controller requires a minimum interval between I2C bus accesses.
51 The default interval is set to 100 us. For manual override, the driver
52 provides a writeable module parameter, 'delay', which can be used to
53 set the interval to a value between 0 and 65,535 microseconds.
59 The following attributes are supported. Limits are read-write; all other
60 attributes are read-only.
