For proper operation, STM32 ADC should be used with a clock duty cycle of 50%, in the range of 49% to 51%. Depending on the clock tree, divider can be used in case clock duty cycle is out of this range. In case clk_get_scaled_duty_cycle() returns an error, kindly apply a divider by default (don't make the probe fail). Signed-off-by:

The aim of this is to improve a bit the organization of ioctl() calls in IIO core. Currently the chardev is split across IIO core sub-modules/files. The main chardev has to be able to handle ioctl() calls, and if we need to add buffer ioctl() calls, this would complicate things. The 'industrialio-core.c' file will provide a 'iio_device_ioctl()' which will iterate over a list of ioctls registered with the IIO device. These can be event ioctl() or buffer ioctl() calls, or something else. Each ioctl() handler will have to return a IIO_IOCTL_UNHANDLED code (which is positive 1), if the ioctl() did not handle the call in any. This eliminates any potential ambiguities about negative error codes, which should fail the call altogether. If any ioctl() returns 0, it was considered that it was serviced successfully and the loop will exit. This change also moves the handling of the IIO_GET_EVENT_FD_IOCTL command inside 'industrialio-event.c', where this is better suited. This patch is a combination of 2 other patches from an older series: Patch 1: iio: core: add simple centralized mechanism for ioctl() handlers Link: https://lore.kernel.org/linux-iio/20200427131100.50845-6-alexandru.ardelean@analog.com/ Patch 2: iio: core: use new common ioctl() mechanism Link: https://lore.kernel.org/linux-iio/20200427131100.50845-7-alexandru.ardelean@analog.com/Signed-off-by:

Replace of_property_read_u32() with device_property_read_u32(), when reading the amstaos,cover-comp-gain.This opens up the possibility of passing the properties during platform instantiation of the device by a suitable populated struct property_entry. Additionally, a minor change in logic is added to remove the of_node present check. Signed-off-by:

This change removes the old platform data for ad7298. It is only used to provide whether to use an external regulator as a reference. So, the logic is inverted a bit. The driver now tries to obtain a regulator. If one is provided, then the external ref is used. The rest of the logic should work as before. Signed-off-by:

The order in which 'users' counter is decremented vs calling drivers' close() method is implementation specific, and we should not rely on it. Let's introduce driver private flag and use it to signal ISR to exit when device is being closed. This has a side-effect of fixing issue of accessing inut->users outside of input->mutex protection.

Add support for setting the hysteresis as a shifted value of a channel's proximity threshold. Each channel can have a different threshold, but the hysteresis applies to all channels as a right shift factor. Therefore, duplicate the hysteresis value across all channels and make it depend on the channel's proximity threshold. This is sort of odd but seems to work in practice as most of the time only one channel is used. Signed-off-by:

This change inverts/reworks the logic to use an external reference via a provided regulator. Now the driver tries to obtain a regulator. If one is found, then it is used. The rest of the driver logic already checks if there is a non-NULL reference to a regulator, so it should be fine. Signed-off-by:
