The change will break existing DTB. Will fix it in v2. The code will need to be like: clk[ckil] = of_clk_get_by_name(ccm_node, "ckil"); if (IS_ERR(clk[ckil])) clk[ckil] = imx_obtain_fixed_clock("ckil", 0); I think the new clock driver will just need to call of_clk_get_by_name() and stay away from imx_obtain_fixed_clock(), but it's unnecessary to churn the existing clock drivers. That said, I will only apply the first patch and drop all others.
