clk: More Range Fixes

[PATCH 0/2] clk: More Range Fixes

Posted by Maxime Ripard 3 years, 5 months ago

Hi,

Here are patches that might address the issues reported by Marek and Mark,
according to Stephen's intuition :)

Either way, it's still fixing and adding test coverage for a regression
introduced by my recent work.

If it's easier for you to test, this series is also pushed here:

It looks it fixes the issue I've reported here: 
https://lore.kernel.org/all/8cdd1927-da38-c23e-fa75-384694724b1c@samsung.com/

All my Amlogic Meson G12A/B based boards work fine after applying those 
fixes.
