The adf4371 has channels that are very closely coupled, so additional documentation is needed to express these constraints. Unfortunately having the same sysfs filename in multiple documentation does not work well when generating automated documentation. To avoid this issue, we add a new device specific description to the main docs and remove the one in the device specific file.

This one is challenging as both the places this appears in specific drivers are making 'unusual' uses of what looks like a simple output current channel. As a side note, this was particular bit of ABI occurs in other drivers where the use is much more straight forward e.g. dac/ad5421 This patch attempts to make a best effort of adding it to the main docs but retaining enough information. Both of these drivers probably need specific documents being written to describe their unusual interfaces, but those should be in the main documentation, not under Documentation/ABI. That is a non trivial job so left for another time.

The interface is standard and the extra info provided on exactly what is being powered down is not of interest to most users. Hence this doesn't need it's own documentation and can rely on the docs in sysfs-bus-iio Fixes $ scripts/get_abi.pl validate Warning: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_powerdown is defined 2 times: ./Documentation/ABI/testing/sysfs-bus-iio-frequency-adf4371:36 ./Documentation/ABI/testing/sysfs-bus-iio:588 Cc: Alexandru Ardelean <alexandru.ardelean@analog.com> Reported-by:

This device has the unusual characteristic that the calibbias values have well defined units (more commonly they are tweaks to a DAC) Unfortunately the previous approach of having more specific documentation in sysfs-bus-iio-icm42600 results in warnings during the documentation build and random ordering in the resulting documentation. To avoid this, add a note to the main documentation on this special characteristic for the icm42600. The _available for calibbias was missing from the main sysfs-bus-iio docs so also add that, allowing us to drop the icm42600 specific file.

With commit 3ba10e37371d ("iio: adis: add burst_max_speed_hz variable"), we just need to define 'burst_max_speed_hz' and the adis core will take care of setting up the spi transfers for burst mode. Hence, we fix a potential race with the spi core where we could be left witn an invalid 'max_speed_hz'.

Typically, in burst mode, the device cannot operate at it's full spi speed. Hence, the spi transfers for burst mode have to take this into account. With this change we avoid a potential race with the spi core as drivers were 'hacking' the device 'max_speed_hz' directly in the trigger handler. Reviewed-by:

There's no point in pushing data to IIO buffers in case 'spi_sync()' fails. Reviewed-by:

It makes more sense to update the device page as soon as we we successfully changed it. Moreover, a follow up patch will handle 'spi_sync' error path which would leave 'current_page' in a inconsistent state. Signed-off-by:

On an IRQ handler we should not return normal error codes as 'irqreturn_t' is expected. This is done by jumping to the 'check_burst32' label where we return 'IRQ_HANDLED'. Note that it is fine to do the burst32 check in this error path. If we have proper settings to apply burst32, we might just do the setup now so that the next sample already uses it.

This binding covers class of simple SPI ADCs which only provide data output - they don't have MOSI pin. The only real variation between them is over how many supplies they use and which one is used for the reference. Michael listed as maintainer for this one as it is his driver and falls under the catch all MAINTAINERS entry for ADI devices. Signed-off-by:

Not all of the parts supported by this driver use single supply. Hence we add chip_info fields to say what additional supplies exist and in the case of vref, ensure that is used for the reference voltage rather than vcc. One corner case is the ad7091r which has an internal reference that can be over-driven by an external reference connected on the vref pin. To handle that force_ext_vref is introduced and set if an optional vref regulator is present. Tested using really simple QEMU model and some fixed regulators. The devm_add_action_or_reset() callback is changed to take the regulator as it's parameter so we can use one callback for all the different regulators without having to store pointers to them in the iio_priv() structure.

Binding documentation for this driver was missing. Note that the binding and some in tree dts files specifiy interrupts etc but the driver is fairly simple and does not yet make use of them.

Linux driver currently relies on the driver.name to match to the compatible, but that doesn't mean it isn't a good idea to document it. Only real complexity is the 3 separate power supplies. Signed-off-by:

These two devices have different internal characteristics, but their external connectivity and as a result device tree descriptions are identical. Note that neither driver in Linux currently has an of_match_table but instead rely on matching via name alone. Signed-off-by:
