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
|
|
-----------
|
|
|
|
The LM75 implements one temperature sensor. Limits can be set through the
|
|
Overtemperature Shutdown register and Hysteresis register. Each value can be
|
|
set and read to half-degree accuracy.
|
|
An alarm is issued (usually to a connected LM78) when the temperature
|
|
gets higher then the Overtemperature Shutdown value; it stays on until
|
|
the temperature falls below the Hysteresis value.
|
|
All temperatures are in degrees Celsius, and are guaranteed within a
|
|
range of -55 to +125 degrees.
|
|
|
|
The driver caches the values for a period varying between 1 second for the
|
|
slowest chips and 125 ms for the fastest chips; reading it more often
|
|
will do no harm, but will return 'old' values.
|
|
|
|
The original LM75 was typically used in combination with LM78-like chips
|
|
on PC motherboards, to measure the temperature of the processor(s). Clones
|
|
are now used in various embedded designs.
|
|
|
|
The LM75 is essentially an industry standard; there may be other
|
|
LM75 clones not listed here, with or without various enhancements,
|
|
that are supported. The clones are not detected by the driver, unless
|
|
they reproduce the exact register tricks of the original LM75, and must
|
|
therefore be instantiated explicitly. Higher resolution up to 16-bit
|
|
is supported by this driver, other specific enhancements are not.
|
|
|
|
The LM77 is not supported, contrary to what we pretended for a long time.
|
|
Both chips are simply not compatible, value encoding differs.
