2015-03-29iio: add support for hardware fifoOctavian Purdila
Some devices have hardware buffers that can store a number of samples for later consumption. Hardware usually provides interrupts to notify the processor when the FIFO is full or when it has reached a certain watermark level. This helps with reducing the number of interrupts to the host processor and thus it helps decreasing the power consumption. This patch enables usage of hardware FIFOs for IIO devices in conjunction with software device buffers. When the hardware FIFO is enabled the samples are stored in the hardware FIFO. The samples are later flushed to the device software buffer when the number of entries in the hardware FIFO reaches the hardware watermark or when a flush operation is triggered by the user when doing a non-blocking read on an empty software device buffer. In order to implement hardware FIFO support the device drivers must implement the following new operations: setting and getting the hardware FIFO watermark level, flushing the hardware FIFO to the software device buffer. The device must also expose information about the hardware FIFO such it's minimum and maximum watermark and if necessary a list of supported watermark values. Finally, the device driver must activate the hardware FIFO when the device buffer is enabled, if the current device settings allows it. The software device buffer watermark is passed by the IIO core to the device driver as a hint for the hardware FIFO watermark. The device driver can adjust this value to allow for hardware limitations (such as capping it to the maximum hardware watermark or adjust it to a value that is supported by the hardware). It can also disable the hardware watermark (and implicitly the hardware FIFO) it this value is below the minimum hardware watermark. Since a driver may support hardware FIFO only when not in triggered buffer mode (due to different semantics of hardware FIFO sampling and triggered sampling) this patch changes the IIO core code to allow falling back to non-triggered buffered mode if no trigger is enabled.

2015-03-29iio: add watermark logic to iio read and pollJosselin Costanzi
Currently the IIO buffer blocking read only wait until at least one data element is available. This patch makes the reader sleep until enough data is collected before returning to userspace. This should limit the read() calls count when trying to get data in batches.

2015-03-28tools: iio: generic_buffer: Fix generic scale extractionIrina Tirdea
When using generic_buffer to read data, the scale is not properly detected for scale shared by type. This is caused by a problem with the generation of generic name out of the full name. E.g.: for current->name in_accel_z, the extracted generic name is "in" (when it should be "in_accel"). This is used in generic_buffer to generate scale and offset paths (in_accel_scale). Consider the in_ or out_ prefix when extracting the generic name from the full name.

2015-03-26staging/lustre/ptlrpc: false alarm in AT network latency measuringLiang Zhen
If early reply of client RPC is lost and client RPC is expired and resent, server will drop the resent RPC because it's already in processing, server may also send reply or early reply to client, which can still match reply buffer of the original request. In this case, client is measuring time from resent time, but server is reporting service time of original RPC, which is longer than the time measured by client.
