These ID's are used as "icc_node->id" while creating the icc_node. So, can't use the duplicate numbers. $ grep TEGRA234_MEMORY_ "include/dt-bindings/memory/tegra234- mc.h" #define TEGRA234_MEMORY_CLIENT_PTCR 0x00 #define TEGRA234_MEMORY_CLIENT_MIU7R 0x01 #define TEGRA234_MEMORY_CLIENT_MIU7W 0x02 #define TEGRA234_MEMORY_CLIENT_MIU8R 0x03 .... Dummy ID's which are already being used are starting from '1000'. So, added to that number as the ID's used for creating "icc_node" for CPU clusters are also dummy and they are not part of HW MC client's list. $ grep "100[0-9]" ./drivers/memory/tegra/mc.h #define TEGRA_ICC_MC 1000 #define TEGRA_ICC_EMC 1001 #define TEGRA_ICC_EMEM 1002
