The core clk framework is left largely untouched this time around except for
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
more excited about the support for loading DT overlays from KUnit tests so that
we can test how the clk framework parses DT nodes during clk registration. The
clk framework has some places that are highly DeviceTree dependent so this
charts the path to extend the KUnit tests to cover even more framework code in
the future. I've got some more tests on the list that use the DT overlay
support, but they uncovered issues with clk unregistration that I'm still
working on fixing.
Outside the core, the clk driver update pile is dominated by Qualcomm and
Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
things all over the place, like adding missing clk frequencies or moving
defines for the number of clks out of DT binding headers into the drivers.
There are even conversions of DT bindings to YAML and migration away from
strings to describe clk topology. Overall it doesn't look unusual so I expect
the new drivers to be where we'll have fixes in the coming weeks.
