| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx. The XADC has a DRP interface for communication. Currently two different frontends for the DRP interface exist. One that is only available on the ZYNQ family as a hardmacro in the SoC portion of the ZYNQ. The other one is available on all series 7 platforms and is a softmacro with a AXI interface. This driver supports both interfaces and internally has a small abstraction layer that hides the specifics of these interfaces from the main driver logic. The ADC has a couple of internal channels which are used for voltage and temperature monitoring of the FPGA as well as one primary and up to 16 channels auxiliary channels for measuring external voltages. The external auxiliary channels can either be directly connected each to one physical pin on the FPGA or they can make use of an external multiplexer which is responsible for multiplexing the external signals onto one pair of physical pins. The voltage and temperature monitoring channels also have an event capability which allows to generate a interrupt when their value falls below or raises above a set threshold. Buffered sampling mode is supported by the driver, but only for AXI-XADC since the ZYNQ XADC interface does not have capabilities for supporting buffer mode (no end-of-conversion interrupt). If buffered mode is supported the driver will register two triggers. One "xadc-samplerate" trigger which will generate samples with the configured samplerate. And one "xadc-convst" trigger which will generate one sample each time the CONVST (conversion start) signal is asserted.

| * | | iio:event: Fix and cleanup lockingLars-Peter Clausen2014-02-231-42/+41Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The event code currently holds a spinlock with IRQs disabled while calling kfifo_to_user(). kfifo_to_user() can generate a page fault though, which means we have to be able to sleep, which is not possible if the interrupts are disabled. The good thing is that kfifo handles concurrent read and write access just fine as long as there is only one reader and one writer, so we do not any locking to protect against concurrent access from the read and writer thread. It is possible though that userspace is trying to read from the event FIFO from multiple concurrent threads, so we need to add locking to protect against this. This is done using a mutex. The mutex will only protect the kfifo_to_user() call, it will not protect the waitqueue. This means that multiple threads can be waiting for new data and once a new event is added to the FIFO all waiting threads will be woken up. If one of those threads is unable to read any data (because another thread already read all the data) it will go back to sleep. The only remaining issue is that now that the clearing of the BUSY flag and the emptying of the FIFO does no longer happen in one atomic step it is possible that a event is added to the FIFO after it has been emptied and this sample will be visible the next time a new event file descriptor is created. To avoid this rather move the emptying of the FIFO from iio_event_chrdev_release to iio_event_getfd().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

Included is the patch previously set as the fourth round for 3.13 which was to late to be appropriate. * Another endian fix (ad799x adc) due to missuse of the IIO_ST macro (which is going away very shortly) * A reversed error check in ad5933 which will make the probe fail. * A buffer overflow in the example code in the documentation. * ad799x was freeing an irq that might or might not have been requested. * tsl2563 was checking the wrong element of chan_spec for modifiers. 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).
