[PATCH 0/2] accel/ivpu: Expose NPU frequency into userspace

[Maciej Falkowski]

This patchset introduces the capability to measure the NPU frequency
and makes it accessible to a userspace via sysfs. The initial patch in the series
addresses the inconsistency in retrieving the clock frequency from
the device across the Meteor Lake and Lunar Lake generations.

Subsequently, the latter patch exposes the driver's frequency
through sysfs to facilitate frequency sampling.
