[PATCH v3 0/3] Add Amlogic Meson GX SoC Clock Measure Driver

[narmstrong@baylibre.com (Neil Armstrong)]

The Amlogic Meson GX SoCs embeds a clock measurer IP to measure the internal
clocks frequencies.
The precision is determined by stepping into the duration until the counter
overflows.
The debugfs shows a pretty summary and each clock can be measured
individually aswell.

This patchset includes the dt-bindings, driver and the DT node added to the
meson-gx dtsi.

Changes since v2 at [2]:
- Removed all reference to GX
- Added compatibles for meson8/meson8b
- Used Martin's suggestions on the divider naming
- Added Martin's meson8/meson8b clk id table
- Added Martin's fixes to support 32bit SoCs

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
