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 valueJacek Anaszewski2013-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A complete refurbished series inclunding: - DT support for the MFD, TSC and ADC driver & platform device support, which has no users, has been killed. - iio_map from last series is gone and replaced by proper nodes in the device tree. - suspend fixes which means correct data structs are taken and no interrupt storm - fifo split which should problem with TSC & ADC beeing used at the same time - The ADC channels are now checked before blindly applied. That means the touch part reads X, Y and Z coordinates and does not mix them up. Same goes for the IIO ADC driver. - The IIO ADC driver now creates files named in_voltageX_raw where X represents the ADC line instead of a number starting at 0. A read from this file can return -EBUSY in case touch is busy and the ADC didn't collect a value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TSC part allows to specify the input lines. The IIO part assumes that it usues always the last few, that means if IIO has adc-channels set to 2 it will use channel 6 and 7. However it might make sense to use only 6. This patch changes the device property (which was introduced recently and was never in an official release) in a way that the user can specify which of the AIN lines should be used. In Addition to this, the name is now AINx where x is the channel number i.e. for AIN6 we would have 6. Prior this, it always started counting at 0 which is confusing. In addition to this, it also checks for correct step number during reading and does not rely on proper FIFO depth.

| | * input: ti_am335x_adc: use only FIFO0 and clean up a littleSebastian Andrzej Siewior2013-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver programs a threshold of "coordinate_readouts" say 5. The REG_FIFO0THR registers says it should it be programmed to "threshold minus one". The driver does not expect just 5 coordinates but 5 * 2 + 2. Multiplied by two because 5 for X and 5 for Y and plus 2 because we have two Z. The whole thing kind of works because It reads the 5 coordinates for X and Y from FIFO0 and FIFO1 and the last element in each FIFO is ignored within the loop and read later. Nothing guaranties that FIFO1 is ready by the time it is read. In fact I could see that that FIFO1 reaturns for Y channels 8,9, 10, 12, 6 and for Y channel 7 for Z. The problem is that channel 7 and channel 12 got somehow mixed up. The other Problem is that FIFO1 is also used by the IIO part leading to wrong results if both (tsc & adc) are used. The patch tries to clean up the whole thing a little: - Remove the +1 and -1 in REG_STEPCONFIG, REG_STEPDELAY and its counter part in the for loop. This is just confusing. - Use only FIFO0 in TSC. The fifo has space for 64 entries so should be fine. - Read the whole FIFO in one function and check the channel. - in case we dawdle around, make sure we only read a multiple of our coordinate set. On the second interrupt we will cleanup the remaining enties. Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code has hard coded value written to step enable bits. Now the bits are updated based on how many steps are needed to be configured got from platform data. The user needs to take care not to exceed the count more than 16. While using ADC and TSC one should take care to set this parameter correctly. Sebastian added the common lock and moved the code, that manipulates the steps, from into the mfd module.

| | * mfd: input: iio: ti_am335x_adc: use one structure for ti_tscadc_devSebastian Andrzej Siewior2013-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mfd driver creates platform data for the child devices and it is the ti_tscadc_dev struct. This struct is copied for the two devices. The copy of the structure makes a common lock in this structure a little less usefull. Therefore the platform data is not a pointer to the structure and the same structure is used. While doing the change I noticed that the suspend/resume code assumes the wrong pointer for ti_tscadc_dev and this has been fixed as well.

* iio: at91_adc: fix missing Sample and Hold timeJean-Christophe PLAGNIOL-VILLARD2013-04-02
| | | | | | | | | | | On the at91_adc a minimal Sample and Hold Time is necessary for the ADC to guarantee the best converted final value between two channels selection. This time has to be programmed through the bitfield SHTIM in the Mode Register ADC_MR.
