Description
|
|
-----------
|
|
|
|
This driver supports hardware monitoring for Intersil / Zilker Labs ZL6100 and
|
|
compatible digital DC-DC controllers.
|
|
|
|
The driver is a client driver to the core PMBus driver. Please see
|
|
Documentation/hwmon/pmbus 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 for
|
|
details.
|
|
|
|
WARNING: Do not access chip registers using the i2cdump command, and do not use
|
|
any of the i2ctools commands on a command register used to save and restore
|
|
configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by
|
|
this driver interpret any access to those command registers (including read
|
|
commands) as request to execute the command in question. Unless write accesses
|
|
to those registers are protected, this may result in power loss, board resets,
|
|
and/or Flash corruption. Worst case, your board may turn into a brick.
|
|
|
|
|
|
Platform data support
|
|
---------------------
|
|
|
|
The driver supports standard PMBus driver platform data.
|
|
|
|
|
|
Module parameters
|
|
-----------------
|
|
|
|
delay
|
|
-----
|
|
|
|
Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C
|
|
bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms
|
|
appears to be sufficient and has not caused any problems in testing. The problem
|
|
is known to affect all currently supported chips. 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_min Minimum input voltage.
|
|
in1_max Maximum input voltage.
|
|

|
|
|
|
vmon attributes are supported on ZL2004, ZL9101M,
|
|
and ZL9117M only.
|
|
|
|

|
|
|
|
X is 3 for ZL2004, ZL9101M, and ZL9117M, 2 otherwise.
