2011-02-28IIO: ADC: AD7476: Update timestamp handlingMichael Hennerich

2011-02-28IIO: Documentation: iio_utils: Prevent buffer overflowMichael Hennerich
The first part of build_channel_array()identifies the number of enabled channels. Further down this count is used to allocate the ci_array. The next section parses the scan_elements directory again, and fills ci_array regardless if the channel is enabled or not. So if less than available channels are enabled ci_array memory is overflowed. This fix makes sure that we allocate enough memory. But the whole approach looks a bit cumbersome to me. Why not allocate memory for MAX_CHANNLES, less say 64 (I never seen a part with more than that channels). And skip the first part entirely.

2011-02-28IIO: ADC: New driver for the AD7298 8-channel SPI ADCMichael Hennerich
This patch adds support for the AD7298: 8-Channel, 1MSPS, 12-Bit SAR ADC with Temperature Sensor via SPI bus. This patch replaces the existing ad7298.c driver completely. It was necessary since, the old driver did not comply with the IIO ABI for such devices. Changes since V1: IIO: ADC: New driver for the AD7298 8-channel SPI ADC Add documentation for new sysfs file tempX_input. Simplify bit defines. Remove outdated comments. Fix indention style. ad7298_show_temp(): Add locking. Simplify temperature calculation. Change temperature result from degrees into milli degrees Celsius. Rename file according to new sysfs ABI documentation Add timestamp attributes. Revise timestamp handling accordingly. Preset timestamp generation.

2011-02-27Staging: hv: add mouse driverGreg Kroah-Hartman
This driver adds mouse support to the hyper-v subsystem. The code was originally written by Citrix, modified heavily by Hank at Microsoft, and then further by me, to get it to build properly due to all of the recent hyperv changes in the tree. At the moment, it is marked "BROKEN" as it has not been tested well, and it will conflict with other api changes that KY is doing, which I will fix up later in this driver. It still needs lots of work, and normal "cleanup". I don't recommend anyone running it on their machine unless they are very brave and know how to debug kernel drivers in a hyperv system.

2011-02-27Staging: samsung-laptop: fix brightness level and add new device idsNils Faerber
The patch is against the 2.6.37 drivers/staging/samsung-laptop driver and implements some extra enhancements. It fixes an issue that the brightness would not change the level at once as well as and some other oddities. It was resolved by reallocated the SABI memory reagion using the "nocache" option. The patch also introduces a new set of supported netbook models, especially the NC10plus which was used for testing this patch. This new set of models also offer 9 instead of just 8 brightness levels so it also introduces an additional parameter for the models struct so that models can define their own brightness range.

This is the bluetooth protocol driver for the TI WiLink7 chipsets. Texas Instrument's WiLink chipsets combine wireless technologies like BT, FM, GPS and WLAN onto a single chip. This Bluetooth driver works on top of the TI_ST shared transport line discipline driver which also allows other drivers like FM V4L2 and GPS character driver to make use of the same UART interface.

xgifb staging driver for XG20, XG21, XG40, XG42 frame buffer device has a accelerator engine that never get used (XGIfb_accel is always 0). Also the driver has a set of defines that hides the synchronization mechanism used to access critical sections and a way to disable spinlocks use at compile time. In a earlier patch all the code that depends on the accelerator being active was deleted because it was dead code. Since the only usage of this synchronization defines were in that dead code, this patch removes all the now unused spinlock conditional compilation logic.
