This driver only turns the power for some regulators on at probe and off via a custom devm_add_action_or_reset() callback. The new devm_regulator_bulk_get_enable() replaces all this boilerplate code. Signed-off-by:

This driver only turns the power on at probe and off via a custom devm_add_action_or_reset() callback. The new devm_regulator_get_enable() replaces this boilerplate code. Note that in event of an error on the devm_regulator_get() the driver would have continued without enabling the regulator which is probably not a good idea. So here we handle any error as a reason to fail the probe(). In theory this may expose breakage on a platform that was previously papered over but it seems low risk. Signed-off-by:

Drop open-coded pattern: 'devm_regulator_get(), regulator_enable(), add_action_or_reset(regulator_disable)' and use the devm_regulator_get_enable() and drop the pointer to the regulator. This simplifies code and makes it less tempting to add manual control for the regulator which is also controlled by devm. Signed-off-by:

Use devm_regulator_bulk_get_enable() instead of open coded bulk-get, bulk-enable, add-action-to-disable-at-detach - pattern. A functional change (which seems like a bugfix) is that if regulator_bulk_get fails, the enable is not attempted. Signed-off-by:

As these exports are only relevant to core module and users in the bus specific modules, move them out of the main kernel namespace. Includes using EXPORT_NS_GPL_DEV_PM_OPS() and the simplifications that brings by allowing the compiler to remove unused struct dev_pm_ops and callbacks without needing explicit __maybe_unused markings.

MPL115 supports shutdown gpio which can be used to set the state to low power mode. Power from all internal circuits and registers is removed. This is done by pulling the SHDN pin to low. This patch enables runtime PM on MPL115 to increase power savings. According to spec., a wakeup time period of ~5 ms exists between waking up and actually communicating with the device. This is implemented using sleep delay. Signed-off-by:

Now that there are no more users accessing 'mlock' directly, we can move it to the iio_dev private structure. Hence, it's now explicit that new driver's should not directly use this lock. Signed-off-by:

The pattern used in this device does not quite fit in the iio_device_claim_direct_mode() typical usage. In this case, we want to know if we are in buffered mode or not to know if the device is powered (buffer mode) or not. And depending on that max30102_get_temp() will power on the device if needed. Hence, in order to keep the same functionality, we try to: 1. Claim Buffered mode; 2: If 1) succeeds call max30102_get_temp() without powering on the device; 3: Release Buffered mode; 4: If 1) fails, Claim Direct mode; 5: If 4) succeeds call max30102_get_temp() with powering on the device; 6: Release Direct mode; 7: If 4) fails, goto to 1) and try again. This dance between buffered and direct mode is not particularly pretty (as well as the loop introduced by the goto statement) but it does allow us to get rid of the mlock usage while keeping the same behavior.

The pattern used in this device does not quite fit in the iio_device_claim_direct_mode() typical usage. In this case, iio_buffer_enabled() was being used not to prevent the raw access but to allow it. Hence, let's make use of the new iio_device_claim_buffer_mode() API to make sure we stay in buffered mode during the complete read. Note that we are shadowing the error code returned by iio_device_claim_buffer_mode() so that we keep the original one (-EAGAIN). The reason is that some userspace stack might already be relying on this particular code so that we are not taking chances and leave it alone. Signed-off-by:

These APIs are analogous to iio_device_claim_direct_mode() and iio_device_release_direct_mode() but, as the name suggests, with the logic flipped. While this looks odd enough, it will have at least two users (in following changes) and it will be important to move the IIO mlock to the private struct. Signed-off-by:
