It might be worth adding a WARN_ON() or similar to this function though so we know if anything ever actually hits it at runtime. Seems like at least some of the other similar stubs do so (omap1 for example).

Provide a simple implementation of clk_set_parent() in the lantiq subarch so that callers of it will build without errors. Fixes these build errors: ERROR: modpost: "clk_set_parent" [sound/soc/jz4740/snd-soc-jz4740-i2s.ko] undefined! ERROR: modpost: "clk_set_parent" [sound/soc/atmel/snd-soc-atmel-i2s.ko] undefined!
