* iio:trigger: Fix use_count race conditionLars-Peter Clausen2013-07-20
| | | | | | | | | | | | | | | | 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.

* iio: Fix iio_channel_has_infoAlexandre Belloni2013-07-02
| | | | | | | | | | | Since the info_mask split, iio_channel_has_info() is not working correctly. info_mask_separate and info_mask_shared_by_type, it is not possible to compare them directly with the iio_chan_info_enum enum. Correct that bit using the BIT() macro.

New stuff 1) Add OF support for specifying mappings between iio devices and their in kernel consumers. 2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and ad7924 added later in series) 3) Driver for Exynos adc (dt suppor for phy added later in series). 4) Make iio_push_event save IRQ context - necessary if it is to be used within an interrupt handler. Users of this functionality to follow. 5) For iio use the device tree node name to provide the hwmon name attribute if available. Removal and moves out of staging 1) Drop the adt7410 driver from IIO now that there is a hmwon driver with equivalent support. This device is very much targeted at hardware monitoring so hwmon is a more appropriate host for the driver. 2) Move iio_hwmon driver to drivers/hwmon. Cleanups 1) Minor cleanup in ST common library. 2) Large set of patches to break the info_mask element which previously used odd and even bits to specify if a channel attribute was either shared across similar channels or specific to only one. Now we have two bitmaps, one for those parameters that are specific to this channel and one for those shared by all channels with the same type as this one. This has no effect on the userspace abi. It simplifies the core code and provides more space for new channel parameters. It has been on the todo list for a long time! Conflicts: drivers/iio/dac/ad5064.c

| | | | | | | | | | | | | | | Some of the newer generation devices from the ADIS16XXX series have more registers than what can be supported with the current register addressing scheme. These devices implement register paging to support a larger register range. Each page is 128 registers large and the currently active page can be selected via register 0x00 in each page. This patch implements transparent paging inside the common adis library. The register read/write interface stays the same and when a register is accessed the library automatically switches to the correct page if it is not already selected. The page number is encoded in the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.

* iio: Introduce a new fractional value typeLars-Peter Clausen2012-09-15
| | | | | | | | | | | | | | | | | | | | | | | Currently IIO uses a decimal fixed point representations for real type numbers. This patch introduces a new representation for rational type numbers. The number will be expressed by specifying a numerator and denominator. For converting a raw value to a processed value multiply it by the numerator and divide it by the denominator. The reasoning for introducing this new type is that for a lot of devices the scale can be represented easily by a fractional number, but it is not possible to represent it as fixed point number without rounding. E.g. for a simple DAC the scale is often the reference voltage divided by the number of possible values (Usually 2**n_bits - 1). Each driver currently implements the conversion of this fraction to a fixed point number on its own. Also when it comes to the in-kernel interface this allows to directly use the fractional factors to convert a raw value to a processed value. This should on one hand require less instructions and on the other hand increase the precision. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
