In this case we only gain the ability to have the compiler drop the struct dev_pm_ops because the callbacks are called from paths other than suspend and resume. In general the purpose of this new macro is to allow automated removal of the callbacks as well, but that doesn't apply here. Signed-off-by:

We can't duplicate the description of sampling_frequency. This device has some unusual requirements which we solved by giving a sampling_frequency of 0 special meaning. As such add a note about this unusual usage to the main documentation. Whilst I don't particularly like this resolution, it is the best I could come up with given earlier discussion on this topic.

Instead of registering callback to process sensor events right at initialization time, wait for the sensor to be register in the iio subsystem. Events can come at probe time (in case the kernel rebooted abruptly without switching the sensor off for instance), and be sent to IIO core before the sensor is fully registered. Fixes: aa984f1b ("iio: cros_ec: Register to cros_ec_sensorhub when EC supports FIFO") Reported-by:

It's not correct to use artificial device created by IIO core to retrieve device properties. Even ->get_default_reg() callback takes a simple struct device pointer which suggests it wants to operate on the real device. Correct this by replacing pointer to IIO device by a real device pointer in the caller of ->get_default_reg(). Signed-off-by:

To provide a new IIO trigger to the IIO core, usually driver executes the following pipeline: allocate()/register()/get(). Before, IIO core assigned trig->owner as a pointer to the module which registered this trigger at the register() stage. But actually the trigger object is owned by the module earlier, on the allocate() stage, when trigger object is successfully allocated for the driver. This patch moves trig->owner initialization from register() stage of trigger initialization pipeline to allocate() stage to eliminate all misunderstandings and time gaps between trigger object creation and owner acquiring.

This patch set is to support bucket in icc-rpm driver, so it implements the similar mechanism in the icc-rpmh driver. It uses interconnect path tag to indicate the bandwidth voting is for which buckets, and there have three kinds of buckets: AWC, WAKE and SLEEP, finally the wake and sleep bucket values are used to set the corresponding clock (active and sleep clocks). So far, we keep the AWC bucket but doesn't really use it. Link: https://lore.kernel.org/r/20220712015929.2789881-1-leo.yan@linaro.org Signed-off-by:
