iio: ti_am335x_adc: Fix wrong samples received on 1st read

2013-07-21T17:27:35Z

Previously we tried to read data form ADC even before ADC sequencer finished sampling. This led to wrong samples. We now wait on ADC status register idle bit to be set. Signed-off-by: Patil, Rachna Signed-off-by: Zubair Lutfullah Signed-off-by: Jonathan Cameron

iio:trigger: Fix use_count race condition

2013-07-20T09:18:53Z

When using more than one trigger consumer it can happen that multiple threads perform a read-modify-update cycle on 'use_count' concurrently. This can cause updates to be lost and use_count can get stuck at non-zero value, in which case the IIO core assumes that at least one thread is still running and will wait for it to finish before running any trigger handlers again. This effectively renders the trigger disabled and a reboot is necessary before it can be used again. To fix this make use_count an atomic variable. Also set it to the number of consumers before starting the first consumer, otherwise it might happen that use_count drops to 0 even though not all consumers have been run yet.

Jonathan writes: The first round of IIO fixes for the 3.11 cycle. This set is larger than I would like, partly due to my lack of review time in the weeks before the merge window and partly because a couple of large drivers and the subsystem as a whole seem to be getting a lot more exposure and testing recently. 1) A long term bug in trigger handling gave a double free of the device. 2) Wrong return value handling means offsets are ignored in iio_convert_raw_to_processed_unlocked. 3) The iio_channel_has_info utility function was incorrectly updated during the recent info_mask split, this is now fixed. 4) mxs-lradc has a couple of little fixes. 5) A couple of missing .driver_module entries meant that drivers could be removed from underneath their users. 6) Error path fixes for ad7303 and lis3l02dq. 7) The scale value for presure in the lps331ap driver was out by a factor of 100.

iio: lps331ap: Fix wrong in_pressure_scale output value

2013-07-16T07:51:57Z

This patch fixes improper in_pressure_scale output that is returned by the lps331ap barometer sensor driver. According to the documentation the pressure after applying the scale has to be expressed in kilopascal units. With erroneous implementation the scale value larger by two orders of magnitude is returned - 2441410 instead of 24414.

Pull MFD update from Samuel Ortiz: "For the 3.11 merge we only have one new MFD driver for the Kontron PLD. But we also have: - Support for the TPS659038 PMIC from the palmas driver. - Intel's Coleto Creek and Avoton SoCs support from the lpc_ich driver. - RTL8411B support from the rtsx driver. - More DT support for the Arizona, max8998, twl4030-power and the ti_am335x_tsadc drivers. - The SSBI driver move under MFD. - A conversion to the devm_* API for most of the MFD drivers. - The twl4030-power got split from twl-core into its own module. - A major ti_am335x_adc cleanup, leading to a proper DT support. - Our regular arizona and wm* updates and cleanups from the Wolfson folks. - A better error handling and initialization, and a regulator subdevice addition for the 88pm80x driver. - A bulk platform_set_drvdata() call removal that's no longer need since commit 0998d0631001 ("device-core: Ensure drvdata = NULL when no driver is bound") * tag 'mfd-3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next: (102 commits) mfd: sec: Provide max_register to regmap mfd: wm8994: Remove duplicate check for active JACKDET MAINTAINERS: Add include directory to MFD file patterns mfd: sec: Remove fields not used since regmap conversion watchdog: Kontron PLD watchdog timer driver mfd: max8998: Add support for Device Tree regulator: max8998: Use arrays for specifying voltages in platform data mfd: max8998: Add irq domain support regulator: palmas: Add TPS659038 support mfd: Kontron PLD mfd driver mfd: palmas: Add TPS659038 PMIC support mfd: palmas: Add SMPS10_BOOST feature mfd: palmas: Check if irq is valid mfd: lpc_ich: iTCO_wdt patch for Intel Coleto Creek DeviceIDs mfd: twl-core: Change TWL6025 references to TWL6032 mfd: davinci_voicecodec: Fix build breakage mfd: vexpress: Make the driver optional for arm and arm64 mfd: htc-egpio: Use devm_ioremap_nocache() instead of ioremap_nocache() mfd: davinci_voicecodec: Convert to use devm_* APIs mfd: twl4030-power: Fix relocking on error ...

iio: inkern: fix iio_convert_raw_to_processed_unlocked

2013-07-03T19:30:52Z

When reading IIO_CHAN_INFO_OFFSET, the return value of iio_channel_read() for success will be IIO_VAL*, checking for 0 is not correct. Without this fix the offset applied by iio drivers will be ignored when converting a raw value to one in appropriate base units (e.g mV) in a IIO client drivers that use iio_convert_raw_to_processed including iio-hwmon.
