I've applied this one but did some corrections [0]: - ppi-partitions is supposed to be a subnode of the gic, that is why the code also start search for it starting from the gic node - I've moved it - I've renamed the phandles taking part0/part1 from the example feels a bit to generic, so it's now ppi_cluster0 and ppi_cluster1 matching the cpu-clusters I've gave this a spin on my rk3399evb and the ppi-partitions got recognized as well as the pmu instances got created, but please also double check again.
