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.Reported-and-tested-by: Stefan Richter

With temperature keys being determined automatically, the dmi match

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.Signed-off-by: Henrik Rydberg

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.Signed-off-by: Henrik Rydberg

The Apple SMC uses a systematic labeling scheme for the hardware
temperature sensors. This scheme is currently hidden from
userland. Since the sensor set, and consequently the numbering,
differs between models, an extensive database of configurations is
required for an application such as fan control. This patch adds the
SMC labels to the hwmon sysfs interface, allowing applications to use
the sensors more intelligibly.[rydberg@euromail.se: fixed error handling]

On resume from suspend, the driver currently resets the logical state as
if it was brought up from halt. This patch uses the
dev_pm_ops.resume/restore methods to synchronize the hardware with the
memorized logical state, in effect bringing back the accelerometer and
backlight to the state prior to suspend. Works for both suspend to ram
and hibernation. The patch has zero effect on the running state.Signed-off-by: Henrik Rydberg

The light sensors ALV0 and ALV1 on newer MacBooks (early 2008 and later)
changed to report 10 bytes instead the earlier 6, and the sensor encoding
subsequently changed. As a result, the reported light sensors readings
are much too low.Via experiments leading up to this patch, it seems only the ALV0 is
reporting data, and the most useful value therein is a 10-bit big-endian
value at offset 6. This suggests that a new protocol was added as a
backward-compatible replacement on top of the old one.This patch makes applesmc report the improved light sensor reading for the
new machines, on a scale in conformance with earlier ones.Signed-off-by: Alex Murray

The read fail ratio is sensitive to the delay between the first byte
written and the first byte read; apparently the sensors cannot be rushed.
Increasing the minimum wait time, without changing the total wait time,
improves the fail ratio from a 8% chance that any of the sensors fails in
one read, down to 0.4%, on a Macbook Air. On a Macbook Pro 3,1, the
effect is even more apparent. By reducing the number of status polls, the
ratio is further improved to below 0.1%. Finally, increasing the total
wait time brings the fail ratio down to virtually zero.Signed-off-by: Henrik Rydberg
