2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

It's been in the works for a long time and it will be interesting to see what hardware support shows up now that this is available. New core features + associate cleanup. * Add generic DMA buffer infrastructure * Add a DMAengine framework based buffer Also associated minor changes. - Set the device buffer watermark based on the minimum watermark for all attached buffers rather than just the 'primary' one. - iio_buffer_init - only set the watermark default if one hasn't already been provided. This allows simple support for devices with a fixed watermark. - read only attribute for watermark on fixed watermark devices. - add explicit buffer enable/disable callbacks to allow the buffer to do more than trivial actions when it is being turned on and off. * IIO_VAL_INT support in write_raw_get_fmt function.

Staging graduation * Dummy driver - this driver acts as both an example and a test device for those with out hardware to develop userspace code against. Cleanups and minor bits and bobs. * treewide - Sort out the ordering of iio_device_register/unregister vs runtime pm function calls so that it's all nice and consistent and not race prone. - Check sscanf return values. None of the cases will actually happen as the strings are supplied internally, but best to be consistent on this. * ad7780 - switch over to the gpio descriptor interface and remove the now unused platform data which gets rid of a header entirely. * ad7793 - drop a pointless else statement. * at91_adc - Swap kmalloc_array in for a kmalloc doing the same job. * dummy - get rid of some commented out lines that snuck in during the move of the driver. * lm3533-als - Print an error message on provision of an invalid resistance. * mcp320x - Add compatible strings with vendor prefix and deprecate those with no vendor prefix. * mxs-lradc - Use BIT macro in various places rather than shifted ones. * pa12203001 - Power off the chip if the registration fails. * pulsedlight-lidar-lite - add runtime PM support. * xilinx XADC - constify an iio_buffer_setup_ops structure.

2015-10-25iio: mma8452: support either of the available interrupt pinsMartin Kepplinger
This change is important in order for everyone to be easily able to use the driver for one of the supported accelerometer chips! Until now, the driver blindly assumed that the INT1 interrupt line is wired on a user's board. But these devices have 2 interrupt lines and can route their interrupt sources to one of them. Now, if "INT2" is found and matches i2c_client->irq, INT2 will be used. The chip's default actually is INT2, which is why probably many boards will have it wired and can make use of this. Of course, this also falls back to assuming INT1, so for existing users nothing will break. The new functionality is described in the bindings doc.
