The RCU (Reset controller Unit) register block provides many different functionalities. Before they were handed by the code in arch/mips/lantiq /xway/reset.c, now there are separate drivers for the functionality. This block provides support for reset controller, GPHY firmware loading, USB PHY initialization and cross bar configuration. These changes are making the old device tree incompatible with the current kernel. The upstream Linux kernel supports loading the device tree blob from the boot loader since about one year, the latest released vendor kernel does not support loading the device tree from a bot loader. I would prefer if this would go through the mips tree. There are more patches planed which would convert the Lantiq code to the common clock framework.
