Mostly cleanup. No new drivers this time around, but support for several chips added to existing drivers: TPS40400, TPS40422, MTD040, MAX34446, ZL9101M, ZL9117M, and LM96080. Also, added watchdog support for SCH56xx, and additional attributes for a couple of drivers. 312869e hwmon: (sch56xx) Add support for the integrated watchdog (v2) 840e191 hwmon: (w83627ehf) Add

Description
|
|
-----------
|
|
|
|
This driver supports hardware montoring for Maxim MAX34440 PMBus 6-Channel
|
|
Power-Supply Manager, MAX34441 PMBus 5-Channel Power-Supply Manager
|
|
and Intelligent Fan Controller, and MAX34446 PMBus Power-Supply Data Logger.
|
|
|
|
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.
|
|
|
|
For MAX34446, the value of the currX_crit attribute determines if current or
|
|
voltage measurement is enabled for a given channel. Voltage measurement is
|
|
enabled if currX_crit is set to 0; current measurement is enabled if the
|
|
attribute is set to a positive value. Power measurement is only enabled if
|
|
channel 1 (3) is configured for voltage measurement, and channel 2 (4) is
|
|
configured for current measurement.
|
|
|
|
|
|
Platform data support
|
|
---------------------
|
|
|
|
The driver supports standard PMBus driver platform data.
|
|
|
|
|
|
