Trivial case where no attributes are valid for some parts. Better handled using two iio_info structures and selecting the right one at probe time. Signed-off-by:

Trivial usecase in which just having two different attr groups covers all options. Slightly more code, but a simpler to follow result. Signed-off-by:

It saves a couple of lines of code but reduces simplicity of code. I generally wish to discourage use of is_visible throughout IIO. Signed-off-by:

We always hold the waitqueue lock when modifying the flags field. So it is safe to use the non-atomic bitops here instead of the atomic versions. The lock has to be held, because we need to clear the busy flag and flush the event FIFO in one atomic operation when closing the event file descriptor. Signed-off-by:

Add poll support to the event queue. This will allow us to check for pending events in a application's event loop using poll() or similar. Since we already have support for blocking reads adding poll support as well is trivial. Signed-off-by:

Use the waitqueue lock to protect the event queue instead of a custom mutex. This has the advantage that we can call the waitqueue operations with the lock held, which simplifies the code flow a bit. Signed-off-by:

The current IIO event code uses a list to emulate FIFO like behavior. Just use a kfifo directly instead to implement the event queue. As part of this patch the maximum of events in the queue is increased from 10 to 16 since kfifo requires a power of two for the number of FIFO elements. Signed-off-by:

The core iio file has gotten quite cluttered over time. This patch moves the event handling code into its own file. Since the event handling code is largely independent from the core code the only code changes necessary for this are to make the moved iio_device_register_eventset, iio_device_unregister_eventset and iio_event_getfd functions non static. This has also the advantage that industrialio-core.c is now closer again to its counterpart in the outofstaging branch. Signed-off-by:

The documentation for the iio_event_interface does not match the actual struct anymore. This patch removes the documentation for non-existing fields and adds documentation for missing fields. Signed-off-by:

Just like isl29018; trivial addition. Using both asahi-kasei,ak8975 and the non-prefixed version (I couldn't figure out if Asahi Kasei had a stock symbol to use, I only found numerical indexes for their stock info). Signed-off-by:

This patch is ported over by me (Ian Abbott) from the out-of-tree Comedi git repository at "git://comedi.org/git/comedi/comedi.git". The original patch is by Nicholas Nell. The patch adds support for trailing (falling) edge external triggers for scans in asynchronous command support in the ni_pcidio driver. This is supported at least on the PCI-DIO_32HS and PCI-6533 boards; not sure about the other boards. Signed-off-by:

When setting up the DMA for 'read' streaming acquisition command, grab the MITE channel spinlock before preparing and arming the DMA. Change inspired by ni_ai_setup_MITE_dma() in ni_mio_common.c. Signed-off-by:

When setting up the DMA for 'read' streaming acquisition on the DIO subdevice, mark the whole buffer as writable before starting the DMA. This prevents a spurious detection of a DMA overwrite of good data during the first interrupt. Problem reported by Nicholas Nell. Fix suggested by Frank Mori Hess. Signed-off-by:

The original patch is by Nicholas Nell. ----- Advantech PCI-1739U support Hello, I've added a bit of simple configuration to adv_pci_dio.c in order to make the PCI-1739U work with the adv_pci_dio driver. I have tested inputs only so far but they seem to work. A git style patch is attached. Thanks, -- Nicholas Nell Professional Research Assistant University of Colorado ----- Signed-off-by:

Paul Fulmek reports that PXIe-6251 works the same as the existing PCIe-6251 and just needs the new PCI device ID adding to ni_pci_table[] and a new entry adding to ni_boards[] based on the existing entry for PCIe-6251. The new entry has PCI device ID 0x72e8 and board name "pxie-6251". Thanks Paul! Signed-off-by:

If allocating 'pdata_urb' fails, the function will return -ENOMEM without freeing the memory allocated, just a few lines above, for 'purb' and will leak that memory when 'purb' goes out of scope. This patch resolves the leak by freeing the allocated storage with usb_free_urb() before the return. Signed-off-by:

Since all the asserts and DBC macros are gone, the kconfig macro CONFIG_TIDSPBRIDGE_DEBUG is not almost used, but for printing trace messages. Since it is almost not used, I don't see any case for keep it churning the configuration menu. This patch removes completely the kconfig macro CONFIG_TIDSPBRIDGE_DEBUG, using only TIDSPBRIDGE_BACKTRACE for enabling the debug trace messages. Signed-off-by:

This macro is only valid when CONFIG_TIDSPBRDIGE_DEBUG is enabled and it only prints a log message, it is not a real assertion mechanism like BUG_ON() or WARN_ON(). It is better to remove them: less code to maintain. Signed-off-by:

The kernel does not use a "Design by Contract" approach, and it is only activated in the module if CONFIG_TIDSPBRDIGE_DEBUG is enabled, so they are executed rarely. It is better to remove them: less code to maintain. Signed-off-by:
