| * iio: adc: at91: don't use the last converted data registerLudovic Desroches2014-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If touchscreen mode is enabled and a conversion is requested on another channel, the result in the last converted data register can be a touchscreen relative value. Starting a conversion involves to do a conversion for all active channel. It starts with ADC channels and ends with touchscreen channels. Then if ADC_LCD register is not read quickly, its content may be a touchscreen conversion. To remove this temporal constraint, the conversion value is taken from the channel data register.

A mixed bag of fixes, many of which feel just to late for 3.15. * hid sensors - some devices need a feature report request in order to change power state. This isn't part of the spec, but has been observed on several devices and does no harm to others. * mpl3115 has had two errors in the buffer description fixed. The presure is signed, not unsigned and the temperature has 12 bits rather than 16. These could lead to incorrect interpretation of the data in userspace. * tsl2x7x - the high byte of the proximity thresholds should be written along with the low byte (which was). This could lead to interesting results with large thresholds. * twl4030 - a flag to specify processed values were required was not set when initializing a reading. As such values returned were in an unknown state. Fixed by simply initializing it appropriately. * IIO_SIMPLE_DUMMY_BUFFER did not select IIO_BUFFER leading to randconfig build errors. * ak8975 was applying an unwanted le16_to_cpu conversion as the i2c framework already performs one. As such for big endian systems, the bytes would be in the wrong order in the magnetic field measurements reported. * mxs-lradc - the controllable voltage dividers were not enabled / disabled for later channels than the first one during conversion. * at91_adc error handling returned -ENOMEM in a u8. Return value of at91_adc_get_trigger_value_by_name changed to int thus allowing -ENOMEM and also original values to be returned. * mcb - mcb_request_mem returns and ERR_PTR but the caller was checking for NULL to detect an error.

Lots of stuff here, tons of cleanup patches, a few new drivers, and some removed as well, but I think we are still adding a few thousand more lines than we remove, due to the new drivers being bigger than the ones deleted. One notible bit of work did stand out, Jes Sorensen has gone on a tear, fixing up a wireless driver to be "more sane" than it originally was from the vendor, with over 500 patches merged here. Good stuff, and a number of users laptops are better off for it.

This (rather late) set consists only of fixes to patches earlier in the cycle or minor fixes for other problems (such as randconfig build issues picked up by Arnd). I've included the general minor fixes here as it is very late in the current cycle and they can all wait for the merge window. * Recent change to hid-sensors introduced a possible infinite loop due to a typo. In the same series, a report interval unit read was added but in the case where the hardware doesn't support it a value of 0 would lead to some nasty issues. The patch sets it to the specified default of msecs. * Anon inodes were used by IIO without being explicitly selected. This has been true for a long time so it clearly only effects rather unusual configurations (rand configs) * at91 requires the input subsytem but this wasn't explicity in the Kconfig. * A couple of parts supported by the max1363 driver were using the wrong iio_chan_spec arrays and hence would missreport their bit depths. This has been there a long time and was never right so isn't a regression.
