iio: Switch i2c drivers back to use .probe()

2023-05-21T17:54:53Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

iio: light: adjd_s311: Convert to i2c's .probe_new()

2022-11-23T20:20:27Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20221118224540.619276-113-uwe@kleine-koenig.org Signed-off-by: Jonathan Cameron

iio: light: adjd_s311: convert probe to device-managed functions

2021-07-17T17:44:18Z

Now that the driver's buffer is stored on the adjd_s311_data private object, the driver is a simple conversion to use only device-managed functions in the probe. The iio_triggered_buffer_setup() and iio_device_register() functions are the only ones needing conversion. And i2c_set_clientdata() is no longer required.

iio: light: adjd_s311: move buffer on adjd_s311_data object

2021-07-17T17:44:18Z

This change moves the entire buffer on the private adjd_s311_data type. Since the device has 4 channels, it's not a big waste to just allocate the maximum possible buffer and use only what's needed. This is in contrast with free-ing and re-allocating the buffer on the update_scan_mode hook. Since the driver pushes buffer data with iio_push_to_buffers_with_timestamp(), the buffer must also include a 64-bit buffer for the timestamp, for each sample-set. With this change, the adjd_s311_update_scan_mode() is no longer needed.

iio: remove explicit IIO device parent assignment

2020-06-14T10:49:59Z

This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment. Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio:core: timestamping clock selection support

2016-06-30T18:41:38Z

Adds a new per-device sysfs attribute "current_timestamp_clock" to allow userspace to select a particular POSIX clock for buffered samples and events timestamping. Following clocks, as listed in clock_gettime(2), are supported: CLOCK_REALTIME, CLOCK_MONOTONIC, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME and CLOCK_TAI.
