This removes the fclkin sysfs attribute and replaces it with getting the CLKIN clock rate using the clk subsystem (i.e. from the devicetree). CLKIN comes from an external oscillator that is connected directly to the AD2S1210 chip, so users of the sysfs attributes should not need to be concerned with this. The fclkin field (the datasheet name) is renamed to clkin_hz to be more obvious that it is a frequency in Hz. Signed-off-by:

This adds an implementation of IIO_CHAN_INFO_SCALE to the ad2s1210 resolver driver. This allows userspace to get the scale factor for the raw values. Signed-off-by:

This removes the special handling for resolutions lower than 16 bits. This will allow us to use a fixed scale independent of the resolution. A new sample field is added to store the raw data instead of reusing the config mode rx buffer so that we don't have to do a cast or worry about unaligned access. Also, for the record, according to the datasheet, the logic for the special handling based on hysteresis that was removed was incorrect. Signed-off-by:

There are quite a few imports and we will be adding more so it will make it easier to read if they are sorted. Signed-off-by:

Since we never call spi_get_drvdata(), we can remove spi_set_drvdata(). Signed-off-by:

This adds a check to the return value of ad2s1210_initial() since it can fail. The call is also moved before devm_iio_device_register() so that we don't have to unregister the device if it fails. Signed-off-by:

This removes the call to spi_setup() in the ad2s1210 driver. Setting MODE_3 was incorrect. It should be MODE_1 but we can let the device tree select this and avoid the need to call spi_setup(). Signed-off-by:

This fixes a use before initialization in ad2s1210_probe(). The ad2s1210_setup_gpios() function uses st->sdev but it was being called before this field was initialized. Signed-off-by:

In theory, this code path should not be reachable because of the previous switch statement. But just in case we should make sure we are restoring the SAMPLE gpio to its original state before returning in addition to releasing the mutex lock. Signed-off-by:

When reading the fault attribute, an empty string was printed if the fault register value was non-zero. This is fixed by checking that the return value is less than zero instead of not zero. Also always print two hex digits while we are touching this line. Signed-off-by:

The deta angle and deta velocity channels were added in parallel with color temperature and chromacity so this merge had to assign a consistent order. I put the color related ones second. Signed-off-by: -

In most cases, ambient color sensors also support the x and y light colors, which represent the coordinates on the CIE 1931 chromaticity diagram. Thus, add light chromaticity x and y for SFH1.1. Signed-off-by:

Sensor hub attributes can be extended to support more channels. Repeat the reading for the two existing channels and store them separately. It still operates in the same manner as before where there was just one entry. So in order to support more sensor hub attributes for ALS use channel index to get specific sensor hub attributes.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
