* iio:gyro: bug on L3GD20H gyroscope supportDenis CIOCCA2014-02-185-9/+5
| | | | | | | | | | | The driver was not able to manage the sensor: during probe function and wai check, the driver stops and writes: "device name and WhoAmI mismatch." The correct value of L3GD20H wai is 0xd7 instead of 0xd4. Dropped support for the sensor.

| | | | | | | | | | | | | | | This patch is fixed [read/write] integration time function. cm36651 have integration time from 1 to 640 milliseconds. But, print more then the thousand second. when call *_integration_time attribute. Because read_integration_time function return IIO_VAL_INT. read integration time function is changed return IIO_VAL_INT_PLUS_MICRO; And then .write_raw_get_fmt callback function for parse a fixed-point number from a string. Some description is revised milliseconds unit. v2: cm36651_write_int_time function fixed as it was.

* iio: max1363: Use devm_regulator_get_optional for optional regulatorGuenter Roeck2014-02-081-1/+1
| | | | | | | | | | | | | In kernel version 3.13, devm_regulator_get() may return no error if a regulator is undeclared. regulator_get_voltage() will return -EINVAL if this happens. This causes the driver to fail loading if the vref regulator is not declared. Since vref is optional, call devm_regulator_get_optional instead.

* iio: ak8975: Fix calculation formula for convert micro tesla to gauss unitBeomho Seo2014-02-081-7/+9
| | | | | | | | | | | | | | This effects the reported scale of the raw values, and thus userspace applications that use this value. One micro tesla equal 0.01 gauss. So I have fixed calculation formula And add RAW_TO_GAUSS macro. ASA is in the range of 0 to 255. If multiply 0.003, calculation result(in_magn_[*]_scale) is always 0. So multiply 3000 and return and IIO_VAL_INT_PLUS_MICRO. As a result, read_raw call back function return accurate scale value.

Thus some sysfs reads would give the wrong values. * A missing dependency on HAS_IOMEM in spear_adc and lpc32xx was causing some test build failures (on s390 and perhaps elsewhere). I also have a few fixes queued up for things that went in during the 3.14 merge window which will follow as a separate pull request (to avoid rebasing my tree).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ADC driver always programs all possible ADC values and discards them except for the value IIO asked for. On the am335x-evm the driver programs four values and it takes 500us to gather them. Reducing the number of conversations down to the (required) one also reduces the busy loop down to 125us. This leads to another error, namely the FIFOCOUNT register is sometimes (like one out of 10 attempts) not updated in time leading to EBUSY. The next read has the FIFOCOUNT register updated. Checking for the ADCSTAT register for being idle isn't a good choice either. The problem is that if TSC is used at the same time, the HW completes the conversation for ADC *and* before the driver noticed it, the HW begins to perform a TSC conversation and so the driver never seen the HW idle. The next time we would have two values in the FIFO but since the driver reads everything we always see the current one. So instead of polling for the IDLE bit in ADCStatus register, we should check the FIFOCOUNT register. It should be one instead of zero because we request one value. This change in turn leads to another error. Sometimes if TSC & ADC are used together the TSC starts generating interrupts even if nobody actually touched the touchscreen. The interrupts seem valid because TSC's FIFO is filled with values for each channel of the TSC. This condition stops after a few ADC reads but will occur again. Not good. On top of this (even without the changes I just mentioned) there is a ADC & TSC lockup condition which was reported to me by Jeff Lance including the following test case: A busy loop of "cat /sys/bus/iio/devices/iio\:device0/in_voltage4_raw" and a mug on touch screen. With this setup, the hardware will lockup after something between 20 minutes and it could take up to a couple of hours. During that lockup, the ADCSTAT register says 0x30 (or 0x70) which means STEP_ID = IDLE and FSM_BUSY = yes. That means the hardware says that it is idle and busy at the same time which is an invalid condition. For all this reasons I decided to rework this TSC/ADC part and add a handshake / synchronization here: First the ADC signals that it needs the HW and writes a 0 mask into the SE register. The HW (if active) will complete the current conversation and become idle. The TSC driver will gather the values from the FIFO (woken up by an interrupt) and won't "enable" another conversation. Instead it will wake up the ADC driver which is already waiting. The ADC driver will start "its" conversation and once it is done, it will enable the TSC steps so the TSC will work again. After this rework I haven't observed the lockup so far. Plus the busy loop has been reduced from 500us to 125us. The continues-read mode remains unchanged.

It should avoid the read-back of the register to avoid the latency and the fact that the bits are reset to 0 after the individual conversation took place. The reason why this is required like this to work, is that read-back of the register removes the bits of the ADC so they do not start another conversation after the register is re-written from the TSC side for the update. To avoid the not required read-back I introduce a "set once" variant which does not update the cache mask. After the conversation completes, the bit is removed from the SE register anyway and we don't plan a new conversation "any time soon". The current set function is renamed to set_cache to distinguish the two operations. This is a small preparation for a larger sync-rework.

New drivers * HID inclinometer driver. * DHT11 humidity driver. Note that previous humidity drivers have been in hwmon, but no one was ever entirely happy with that, and they should find a more comfortable home in IIO (their original placement in hwmon was my fault - oops). As this is our first humidity driver, core support is also added. New features * Two of mxs-lradc channels are internally wired to a temperature sensor, make this explicit in the driver by providing the relevant temperature channel. * Add support for blocking IO on buffers. * Add a data_available call back to the interface between buffer implementations and the core. This is much cleaner than the old, 'stufftoread' flag. Implemented in the kfifo buffer. Cleanups * Last user of the old event configuration interface is converted and the old interface dropped. Nice to be rid of this thanks to Lars-Peter's hard work! * Replace all remaining instances of the IIO_ST macro with explicit filling of the scan_type structure within struct iio_chan_spec. This macro was a bad idea, that rapidly ceased to cover all elements of the structure. Miss reading of the macro arguements has led to a number of bugs so lets just get rid of it. The final removal patch is awaiting for some fixes to make their way into mainline. In a couple of drivers, no elements of scan_type were even being used so in those case, it has been dropped entirely. * Drop a couple of of_match_ptr helper uses in drivers where devicetree is not optional and hence the structures being protected by this always exist. * Fix up some cases where data was read from a device in a particular byte order, but he code placed it into a s16 or similar. These were highlighted by Sparse. * Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers core code. * ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code and possibly avoiding issues with i2c bus drivers that assume they can dma directly into the buffer. Note that this cannot currently happen as the the i2c_smbus_read_i2c_block_data function has a memcpy from the buffer actually passed to the bus driver. I missed this element of the commit message and don't think it is major enough to rebase the iio tree. * ad5791 and ad5504 stop storing buffers on the stack for an SPI driver. Unlike the i2c drivers, this is a real issue for SPI drivers which can dma directly into the buffer supplied.

| * | | | iio: Add support for blocking IO on buffersLars-Peter Clausen2013-12-031-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the IIO buffer interface only allows non-blocking reads. This patch adds support for blocking IO. In blocking mode the thread will go to sleep if no data is available and will wait for the buffer implementation to signal that new data is available by waking up the buffers waitqueue.

| * | | | iio: kfifo_buf: Implement data_available() callbackLars-Peter Clausen2013-12-031-9/+14

The kfifo used by the buffer already knows whether it is empty or not based on the position of its read and write pointer. Using this makes it a lot easier to tell whether data is available or not and it is not necessary to take special measures to ensure that no race conditions between reading and writing from the buffer occur. Note, that we still have to take the buffers lock to protect against concurrent resizeing of the kfifo.

| * | | | iio: Add data_available callback for buffersLars-Peter Clausen2013-12-031-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new data_available() callback to the iio_buffer_access_funcs struct. The callback is used to indicate whether data is available in the buffer for reading. It is meant to replace the stufftoread flag from the iio_buffer struct. The reasoning for this is that the buffer implementation usually can determine whether data is available rather easily based on its state, on the other hand it can be rather tricky to update the stufftoread flag in a race free way.
