2021-11-17iio: at91-sama5d2: Use dev_to_iio_dev() in sysfs callbacksLars-Peter Clausen
Using `dev_get_drvdata()` in IIO sysfs callbacks to get a pointer to the IIO device is a relic from the very early days of IIO. The IIO core as well as most other drivers have switched over to using `dev_to_iio_dev()` instead. This driver is one of the last few drivers remaining that uses the outdated idiom, update it. This will allow to eventually update the IIO core to no longer set the drvdata for the IIO device and free it up for driver usage.

2021-11-17iio: at91-sama5d2: Fix incorrect cast to platform_deviceLars-Peter Clausen
The at91-sama5d2 driver calls `to_platform_device()` on a struct device that is part of a IIO device. This is incorrect since `to_platform_device()` must only be called on a struct device that is part of a platform device. The code still works by accident because non of the struct platform_device specific fields are accessed. Refactor the code a bit so that it behaves identically, but does not use the incorrect cast. This avoids accidentally adding undefined behavior in the future by assuming the `struct platform_device` is actually valid.

2021-11-17iio: imx7d_adc: Don't pass IIO device to imx7d_adc_{enable,disable}()Lars-Peter Clausen
The `imx7d_adc_enable()` and `imx7d_adc_disable()` functions are used as the suspend and resume callbacks for the device. When called as suspend/resume functions they are called with the platform_device's device as their parameter. In addition the functions are called on device probe and remove. In this case they are passed the struct device of the IIO device that the driver registers. This works because in the `imx7d_adc_{enable,disable}()` functions the passed struct device is only ever used as a parameter to `dev_get_drvdata()` and `dev_get_drvdata()` returns the same value for the platform device and the IIO device. But for consistency we should pass the same struct device to the `imx7d_adc_{enable,disable}()` in all cases. This will avoid accidental breakage if the device is ever used for something more than `dev_get_drvdata()`. Another motivation is that `dev_get_drvdata()` on the IIO device relies on the IIO core calling `dev_set_drvdata()`. Something we want to remove.

2021-11-17iio: xilinx-xadc: Make IRQ optionalLars-Peter Clausen
In some setups the IRQ signal of the XADC might not be wired to the host system. The driver currently requires that an interrupt is specified. Make the interrupt optional so the driver can be used in such setups where the interrupt is not connected. Since both the internal triggers as well as events depend on the interrupt being connected both are not available when the interrupt is not connected. Buffered access is still supported even without an interrupt since an external trigger can be used. The IRQ is only optional when using the AXI interface, since the PCAP interface needs the IRQ for reading and writing registers.

2021-10-21iio: adc: ti_am335x_adc: Wait the idle state to avoid stallsMiquel Raynal
At least on a am4372, a simple: $ cat /sys/bus/iio/devices/iio\:deviceX/in_voltage*_raw can stall forever. It seems that it comes from the fact that the internal state machine does not have enough time to return to its idle state in this situation before receiving another request, leading to an internal stall. Add a tiadc_wait_idle() helper to ensure no new conversion is requested while the FSM is still busy.
