Again, this is an ABI break. Changing driver architecture for 1 OS is not a reason to change DT. Rob

I thought that since the NPCM8xx clock driver hasn't upstream the kernel vanilla yet and and in the latest NPCM8xx clock driver patch the NPCM8xx clock driver. using auxiliary device framework instead of DT we should remove the nuvoton,npcm845-clk.yaml file. https://patchwork.kernel.org/project/linux-clk/patch/20240509192411.2432066-4-tmaimon77@gmail.com/ > > Rob Thanks, Tomer

Anyway, once binding is released other users might start to use it, so yeah, could still be ABI break. Best regards, Krzysztof
