hwmon: (applesmc) Properly initialize lockdep attributes

2011-01-23T17:28:50+00:00

The switch to dynamically allocated sysfs attributes left the
internal lockdep members uninitialized, causing a formal bug.
This patch adds sysfs_attr_init() to the node creation function,
remedying the problem.

hwmon: (applesmc) Fix checkpatch errors and fix value range checks

2011-01-08T18:55:46+00:00

This patch fixes all checkpatch errors and most of the checkpatch warnings.
It also fixes the range check in applesmc_store_fan_speed().

hwmon: (applesmc) Update copyright information

2011-01-08T18:55:45+00:00

With the preceding patches, git blame assigns about half of
the file to the present author. Add a line to the copyright
to reflect this.

hwmon: (applesmc) Simplify feature sysfs handling

2011-01-08T18:55:43+00:00

Given the dynamic node construction method, the setup of the
accelerometer, light sensor and keyboard backlight sysfs nodes
can be simplified. This patch does not contain any logic changes.

hwmon: (applesmc) Dynamic creation of fan files

2011-01-08T18:55:42+00:00

With the dynamic temperature group in place, the setup of fans
can be simplified. This patch sets up the fans dynamically, removing
a hundred lines of code.

hwmon: (applesmc) Extract all features generically

2011-01-08T18:55:41+00:00

With temperature keys being determined automatically, the dmi match
data is only used to assign features that can easily be detected from
the smc. This patch removes the dmi match data altogether, and reduces
the match table to the main machine models.

hwmon: (applesmc) Handle new temperature format

2011-01-08T18:55:40+00:00

The recent Macbooks have temperature registers of a new type.
This patch adds the logic to handle them.

hwmon: (applesmc) Dynamic creation of temperature files

2011-01-08T18:55:39+00:00

The current driver creates temperature files based on a list
of temperature keys given per device. Apart from slow adaption
to new machine models, the number of sensors also depends on
the number of processors. This patch looks up the temperature
keys dynamically, thereby supporting all models.

hwmon: (applesmc) Introduce a register lookup table

2011-01-08T18:55:38+00:00

One main problem with the current driver is the inability to quickly
search for supported keys, resulting in detailed feature maps per
machine model which are cumbersome to maintain.

This patch adds a register lookup table, which enables binary search
for supported keys. The lookup also reduces the io frequency, so the
original mutex is replaced by locks around the actual io.
