1537078d8f sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

f64b57408f Check error return from reading integer part of temperature.
There's a very remote, but possible, chance that the integer part read will
fail, but the fraction read succeeds, at which point the reported temperature is
invalid.

76f5b95a89 Fix some integer signs. These unsigned integers should all be signed.

86338f41d2 Avoid using the degree symbol. Looks ugly on the console. 2012-08-19 19:32:38 +00:00

e97eae1577 Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.
This means that their use is restricted to a single C file.

a482702706 Move the celsius-to-kelvin conversion to a place that powermac_thermal can
see it as well.

95e41991d8 Update the I2C-based temperature/fan drivers to connect to the Powermac
thermal control module. This provides automatic fan management on all G5
PowerMacs and Xserves.

1cef14c1d4 Add three new drivers for fan control and temperature reading on the
PowerMac7,2.

- The fcu driver lets us read and write the fan RPMs for all fans in the
  PowerMac7,2. This driver is PowerMac specific.
- The ds1775 is a driver to read the temperature for the drive bay sensor.
- The max6690 is another driver to read temperatures. Here it is used to
  read the inlet, the backside and the U3 heatsink temperature.

An additional driver, the ad7417, will follow later.

Thanks to nwhitehorn for guiding me through this driver development.
