iio: Move attach/detach of the poll func to the core

2020-06-20T16:34:44Z

All devices using a triggered buffer need to attach and detach the trigger to the device in order to properly work. Instead of doing this in each and every driver by hand move this into the core. At this point in time, all drivers should have been resolved to attach/detach the poll-function in the same order. This patch removes all explicit calls of iio_triggered_buffer_postenable() & iio_triggered_buffer_predisable() in all drivers, since the core handles now the pollfunc attach/detach. The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's not immediately obvious that removing the hooks doesn't break anything. Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board. All seems to be fine.

iio: core: pass parent device as parameter during allocation

2020-06-14T10:49:56Z

The change passes the parent device to the iio_device_alloc() call. This also updates the devm_iio_device_alloc() call to consider the device object as the parent device by default. Having it passed like this, should ensure that any IIO device object already has a device object as parent, allowing for neater control, like passing the 'indio_dev' object for other stuff [like buffers/triggers/etc], and potentially creating iiom_xxx(indio_dev) functions. With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an update to pass the parent object as a parameter. In the next patch all devm_iio_device_alloc() calls will be handled.

iio: dummy_evgen: Fix use after free on error in iio_dummy_evgen_create()

2020-05-20T12:11:41Z

We need to preserve the "iio_evgen->irq_sim_domain" error code before we free "iio_evgen" otherwise it leads to a use after free. Fixes: 337cbeb2c13e ("genirq/irq_sim: Simplify the API") Signed-off-by: Dan Carpenter Signed-off-by: Marc Zyngier

genirq/irq_sim: Simplify the API

2020-05-18T09:30:21Z

The interrupt simulator API exposes a lot of custom data structures and functions and doesn't reuse the interfaces already exposed by the irq subsystem. This patch tries to address it. We hide all the simulator-related data structures from users and instead rely on the well-known irq domain. When creating the interrupt simulator the user receives a pointer to a newly created irq_domain and can use it to create mappings for simulated interrupts. It is also possible to pass a handle to fwnode when creating the simulator domain and retrieve it using irq_find_matching_fwnode(). The irq_sim_fire() function is dropped as well. Instead we implement the irq_get/set_irqchip_state interface. We modify the two modules that use the simulator at the same time as adding these changes in order to reduce the intermediate bloat that would result when trying to migrate the drivers in separate patches.

spi: docs: convert to ReST and add it to the kABI bookset
