iio: accel: bma180: Fix indio_dev->trig assignment

2014-08-25T20:48:04+00:00

This can result in wrong reference count for trigger device, call iio_trigger_get to increment reference. Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion with Jonathan. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron Cc: Stable@vger.kernel.org

Pull staging driver updates from Greg KH: "Here's the big pull request for the staging driver tree for 3.17-rc1. Lots of things in here, over 2000 patches, but the best part is this: 1480 files changed, 39070 insertions(+), 254659 deletions(-) Thanks to the great work of Kristina Martšenko, 14 different staging drivers have been removed from the tree as they were obsolete and no one was willing to work on cleaning them up. Other than the driver removals, loads of cleanups are in here (comedi, lustre, etc.) as well as the usual IIO driver updates and additions. All of this has been in the linux-next tree for a while" * tag 'staging-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (2199 commits) staging: comedi: addi_apci_1564: remove diagnostic interrupt support code staging: comedi: addi_apci_1564: add subdevice to check diagnostic status staging: wlan-ng: coding style problem fix staging: wlan-ng: fixing coding style problems staging: comedi: ii_pci20kc: request and ioremap memory staging: lustre: bitwise vs logical typo staging: dgnc: Remove unneeded dgnc_trace.c and dgnc_trace.h staging: dgnc: rephrase comment staging: comedi: ni_tio: remove some dead code staging: rtl8723au: Fix static symbol sparse warning staging: rtl8723au: usb_dvobj_init(): Remove unused variable 'pdev_desc' staging: rtl8723au: Do not duplicate kernel provided USB macros staging: rtl8723au: Remove never set struct pwrctrl_priv.bHWPowerdown staging: rtl8723au: Remove two never set variables staging: rtl8723au: RSSI_test is never set staging:r8190: coding style: Fixed checkpatch reported Error staging:r8180: coding style: Fixed too long lines staging:r8180: coding style: Fixed commenting style staging: lustre: ptlrpc: lproc_ptlrpc.c - fix dereferenceing user space buffer staging: lustre: ldlm: ldlm_resource.c - fix dereferenceing user space buffer ...

Jonathan writes: Fourth round of IIO new drivers, functionality and cleanups for the 3.17 cycle New functionality * A new modifier to indicate that a rotation is relative to either true or magnetic north. This is to be used by some magnetometers that provide data in this way. * hid magnetometer now supports output rotations from various variants on North * HMC5843 driver converted to regmap and reworked to allow easy support of other similar devices. Support for HMC5983 added via both i2c and SPI. * Rework of Exynos driver to simplify extension to support more devices. * Addition of support for the Exynos3250 ADC (which requires an additional clock) Support for quite a few more devices on its way. Cleanups * ad7997 - a number of cleanups and tweaks to how the events are controlled to make it more intuitive. * kxcjk - cleanups and minor fixes for this new driver.

iio:kxcjk-1013: Fix endianness in scan_type

2014-07-20T16:52:15+00:00

driver uses i2c_smbus_read_word_data() to the data in the trigger handler and hence already does endianness conversion; the I2C chip has data in little endian, but the value is provides in CPU endianness Signed-off-by: Peter Meerwald Reviewed-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio:bma180: Missing check for frequency fractional part

2014-07-20T16:39:47+00:00

val2 should be zero This will make no difference for correct inputs but will reject incorrect ones with a decimal part in the value written to the sysfs interface. Signed-off-by: Peter Meerwald Cc: Oleksandr Kravchenko Signed-off-by: Jonathan Cameron Cc: Stable@vger.kernel.org

iio:bma180: Fix scale factors to report correct acceleration units

2014-07-20T16:38:39+00:00

The userspace interface for acceleration sensors is documented as using m/s^2 units [Documentation/ABI/testing/sysfs-bus-iio] The fullscale raw values for the BMA80 corresponds to -/+ 1, 1.5, 2, etc G depending on the selected mode. The scale table was converting to G rather than m/s^2. Change the scaling table to match the documented interface. See commit 71702e6e, iio: mma8452: Use correct acceleration units, for a related fix.

iio: accel: kxcjk-1013: Increment ref counter for indio_dev->trig

2014-07-20T15:37:52+00:00

Assigning indio_dev->trig is not a good idea, as this can result in wrong reference count for trigger device. If assigned, it is better to increment reference counter by calling iio_trigger_get.

iio: accel: kxcjk-1013: Use try_reenable to ack intr

2014-07-20T15:24:22+00:00

This chip needs explicit interrupt ack, introducing try_reenable callback. Also removed separate function to ack interrupt as this doesn't add any value. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: accel: kxcjk-1013: Fix setting frequency

2014-07-20T15:18:58+00:00

Fix issue with setting of 12.5 and 6.25 HZ. The match of val2 fails. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron
