The i.MX8M differntiates between three types of composite clocks (called slices): Core, Bus and IP (peripheral) clocks. How muxes are configured differs between these clocks, so the driver is populating a mux_ops variable to point at the correct struct clk_ops. Unfortunately, mux_ops wasn't actually used, leading to barebox hangs, depending on the assigned-clock-parents properties in the device tree. This is correct here. The issues were observed on an i.MX8MP.
