Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Description
|
|
-----------
|
|
|
|
This driver supports hardware monitoring 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.
|
|
It also supports the MAX34451, MAX34460, and MAX34461 PMBus Voltage Monitor &
|
|
Sequencers. The MAX34451 supports monitoring voltage or current of 12 channels
|
|
based on GIN pins. The MAX34460 supports 12 voltage channels, and the MAX34461
|
|
supports 16 voltage channels.
|
|
|
|
The driver is a client driver to the core PMBus driver. Please see
|
|
Documentation/hwmon/pmbus.rst 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.
|
|
|
|
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.
|
|
|
