I will try to add more description in the binding for cluster; And the structure of dsp cluster (like sub node of DSP cluster is core, etc). Did I get your feedback right? > > -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
