i2c: Remove obsolete cleanup for clientdata

2010-09-30T12:14:22+00:00

A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit. This is obsolete meanwhile, so fix it and hope the word will spread.

vmware balloon: rename module

2010-09-23T00:22:38+00:00

In an effort to minimize customer confusion we want to unify naming
convention for VMware-provided kernel modules.  This change renames the
balloon driver from vmware_ballon to vmw_balloon.

We expect to follow this naming convention (vmw_) for all
modules that are part of mainline kernel and/or being distributed by
VMware, with the sole exception of vmxnet3 driver (since the name of
mainline driver happens to match with the name used in VMware Tools).

cs5535-mfgpt: reuse timers that have never been set up

2010-08-11T15:59:20+00:00

The MFGPT hardware may be set up only once, therefore
cs5535_mfgpt_free_timer() didn't re-set the timer's "avail" bit.  However
if a timer is freed before it has actually been in use then it may be made
available again.

param: remove unnecessary writable charp

2010-08-11T13:34:27+00:00

sysfs-writable charp arguments need to be locked against modification
(since the old ones may be kfreed underneath us).  String arguments
are much simpler, so use them for small strings (eg. IFNAMSIZ).

lkdtm only uses the parameters at module initialization time, so there's
not much point making them writable.

hmc6352: add driver for the HMC6352 compass

2010-08-10T03:45:10+00:00

This driver will report the heading values in degrees to the sysfs
interface.  The values returned are headings .  e.g.  245.6

Alan: Cleanups requested now all folded in and a sysfs description to keep
Andrew happy. The sysfs description now resembles hwmon.

drivers/misc: support for the pressure sensor BMP085 from Bosch Sensortec

2010-08-10T03:45:05+00:00

This driver adds support for the BMP085 digital pressure sensor from Bosch
Sensortec.  It exposes a sysfs api to userspace where pressure and
temperature measurement results can be read from the pressure0_input and
temp0_input file.  The chip is able to calculate the average of up to
eight samples to increase the accuracy.  This feature can be controlled by
writing to the oversampling file.

The BMP085 digital pressure sensor can measure ambient air pressure and
temperature.  Both values can be obtained from sysfs files.  The pressure
is measured by reading from pressure0_input.  Valid values range from
30000 to 110000 pascal with a resolution of 1 pascal (=0.01 millibar).

temp0_input holds the current temperature in degree celsius, multiplied by
10.  This results in a resolution of a tenth degree celsius.  Values range
from -400 to 850.

To increase the accuracy, this chip can calculate the average of 1, 2, 4
or 8 samples.  This behavior is controlled through the oversampling sysfs
file.  Two to the power of the value written to that file specifies how
many samples will be used.  Valid values: 0..3.

drivers/misc: ROHM BH1780GLI ambient light sensor driver

2010-08-10T03:45:05+00:00

Add support for ROHM BH1780GLI Ambient light sensor.

BH1780 supports I2C interface.  Driver supports read/update of power state
and read of lux value (through SYSFS).  Writing value 3 to power_state
enables the sensor and current lux value could be read.

Currently this driver follows the same sysfs convention as supported by
drivers/misc/isl29003.c.
