|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: "First round of iio fixes post the 3.9 merge window. 1) Some little fixes for the ad5064 dac driver. 2) A build warning 'fix' for a false positive in st_sensors 3) A couple of missing dependencies on IIO_BUFFER. So nothing major and these mostly showed the advantages of the randconfig builds various people have performed."

| | | | | | | | | | | | | | | | The DAC value range check allows values one larger than the maximum value, which effectively results in setting the DAC value to 0. This patch fixes the issue. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
| * iio:ad5064: Fix address of the second channel for ad5065/ad5045/ad5025Lars-Peter Clausen2013-03-021-20/+29
| | | | | | | | | | | | | | | | | | | | | | The ad5065, ad5045, ad5025 use address '3' for the second channel, so they need their own channel spec. Note that ad5064_sync_powerdown_mode() also needs to be slightly updated since it was relying on the fact that chan->address always equaled chan->channel.

This driver already covers a large set of new parts (20 gyros, accelerometer and magnetometers) not currently covered by the existing drivers. The intent moving forward is to merge this with the other drivers for similar parts already in tree. The lis3l02dq driver currently in staging/iio will be trivial, the lis3 driver in misc more complex as it has a number of additional interfaces. Any merging in of the lis3 driver will rely on the not currently merged iio_input bridge driver and handling of freefall notifications etc. 2) A driver for the itg3200 gyroscope. Graduations from staging 1) Cleanup and move out of staging of the adxrs450 gyroscope driver. The cleanup required was all minor but there were a couple of fixes hidden in there. Core and driver additions 1) Initial work from Guenter Roeck on device tree support for IIO's provider/ consumer code. Focuses on the iio_hwmon driver and the max1363 adc driver. The full device tree syntax is currently under discussion but should follow shortly. Cleanups and fixes 1) Remove a noop function __iio_update_buffer 2) Couple of small fixes and cleanups for the max1363 "

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For chips with more than 8 bit ADC resolution, received data was always masked against 0xfff, ie with a 12 bit mask. This can result in bad data for chips with 10 bit resolution if those chips have higher bits set (seen with MAX1139). The receive buffer was defined as char array. This could result in unintentional sign extensions if the upper bit in a received byte was set. Since the chip is configured for unipolar mode, we never have to handle negative values, and sign extensions are never needed.

But the only user of this function just passes in these exact fields, so the call basically looks like this: buffer->bytes_per_datum = buffer->bytes_per_datum; buffer->length = buffer->length; Which means it is a noop and can be removed. Also remove the function itself, since it is now unused. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

Well, the omapdrm fixes aren't really "small" but they were waiting on a number of other drm patches to go in through the drm tree, and got delayed by my vacation over the holidays. They are totally self-contained, everyone involved have acked them, and they fix issues that people have been having with the driver. Other than that one, it's a bunch of tiny bugfixes for a number of reported issues.

Fix it. Driver should also not attempt to free the interrupt in its error path if none was allocated. Fix that problem as well. Finally, testing if the regulator was allocated is not necessary in the remove function, since the probe function bails out if this is the case. Remove that check.
