Simple conversion with a few minor tweaks: * I added 1MHz max for spi-max-frequency * I have give myself as the maintainer. This driver was written by Gregor Boirie but I don't have an up to date email address for Gregor. Signed-off-by:

Very simple binding for this i2c device with no properties beyond reg and compatible. Hence doesn't need it's own document. Signed-off-by:

Jonathan Cameron authored
The conversion is straight forward, but leaves an open question. The compatible for this device has never had a vendor. Harald Geyer has identified as probably being made by aosong, but we have no current match to any of their more specific part numbers. As such, this is noted in the file but the compatible doesn't include the vendor prefix. Signed-off-by:

This is conversion of the driver to use device-managed functions. The IIO registration and triggered buffer setup both have device-managed versions. The regulator disable needs to be handled via an action_or_reset handler. With these changes, the remove hook is removed, and the error path is cleaned up in probe. Signed-off-by:

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:

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.
