[U-Boot] [PATCH] powerpc/mpc85xx:Avoid fix clk groups for Cluster & HW accelerator
CHASSIS2 architecture never fix clock groups for Cluster and hardware accelerator like PME, FMA. These are SoC defined. SoC defines :- - NUM of PLLs present in the system - Clusters and their Clock group - hardware accelerator and their clock group if no clock group, then platform clock divider for FMAN, PME
