This patch series adds basic clock, reset & DT support for StarFive JH7110 SoC. @Stephen and @Conor, I have made this series start with the shared dt-bindings, so it will be easier to merge. @Conor, patch 1, 2, 16~21 were already in your branch. Patch 22 is the same with the patch [1] I submitted before, which you had accepted but not merge it into your branch. You can simply review or test the patches at the link [2]. Hope this series will be merged soon.
