Subject: [PATCH 0/2] iio: frequency: add iio support for Amlogic clock measure
Date: Mon, 24 Jun 2024 19:31:01 +0200	[thread overview]
Message-ID: <20240624173105.909554-1-jbrunet@baylibre.com> (raw)

Add support for the HW found in most Amlogic SoC dedicated to measure
system clocks.

This drivers aims to replace the one found in
drivers/soc/amlogic/meson-clk-measure.c with following improvements:

* Access to the measurements through the IIO API:
  Easier re-use of the results in userspace and other drivers
* Controllable scale with raw measurements
* Higher precision with processed measurements
