It seems as if the conclusion was that the patch is at the right location omap5xxx_dt_clk_init(). Has it been merged somewhere? It seems as if we still need it in our 5.10-rc series: https://git.goldelico.com/?p=letux-kernel.git;a=commit;h=aa8eda144e8faa185e154710ca0eef12adb2d29d BR and thanks, Nikolaus
