Subject: [PATCH v2 0/3] Add Amlogic Meson GX SoC Clock Measure Driver
The Amlogic Meson GX SoCs embeds a clock measurer IP to measure the internal
clocks frequencyies.
The precision is determined by stepping into the divider until the counter
overflows.
The debugfs slows a pretty summary and each clock can be measured
individually aswell.
Thsi patchset includes the dt-bindings, driver and the DT node added to the
meson-gx dtsi.
Changes since v1 at [1]:
- fixed clock names
- added summary in debugfs and moved indivudual clocks into a subdirectory
- added the GX table to the match data
