Converted to maintain the requirement for Vdd-supply as per original file. It is possible we could relax this requirement to make it at least one of Vdd-supply and REF-supply. We need to establish the scaling of the output channel and if REF-supply is provided that is used instead of Vdd-supply, hence I cannot see why a dummy regulator cannot be used for Vdd-supply if this happens. For now, let us keep it simple. Drop adi,use-external-reference from binding example as no such binding exists. Signed-off-by:

This one is a bit interesting because the binding was moved from misc a while back, but the linux support for this device is provided via the ad5446 DAC driver which doesn't currently have a binding. For now, lets just convert this file over, but we may want to think about consolidating this with proper documentation of the bindings for the other parts supported by the ad5446 driver. As Daniel Mack does not seem to have been active since 2015, I've put myself as maintainer of this binding for now. Signed-off-by:

A few tweaks in this conversion. * The example didn't have the I2C address of 4C in the node name so fixed that. * The reference voltage in the txt file is an optional binding, but the driver is making use of it to provide the scaling of the output channels. As such I have made it required going forwards. Signed-off-by:

Simple conversion. There hasn't been much activity around this driver for a long time and I don't think I have any up to date contact details for the original authors. As such, I've listed myself as the binding maintainer. More than happy to hand it off to someone more relevant though! Signed-off-by:

One quirk in the txt file was that the xclr gpio was specified as xclr-gpio rather than xclr-gpios. I've fixed that in the yaml version. 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:

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.
