--------------------------------
[ Upstream commit fc1aabb088860d6cf9dd03612b7a6f0de91ccac2 ]
Provide a simple implementation of clk_get_parent() in the lantiq subarch so that callers of it will build without errors.
Fixes this build error: ERROR: modpost: "clk_get_parent" [drivers/iio/adc/ingenic-adc.ko] undefined!
