[PATCH V2 0/2] Add complex scheduler level for arm64

From: Wang Qing <redacted>

The DSU cluster supports blocks that are called complexes
which contain up to two cores of the same type and some shared logic,
which sharing some logic between the cores can make a complex area efficient.

Complex also can be considered as a shared cache group smaller
than cluster.

This patch adds complex level for complexs by parsing cache topology
form DT. It will directly benefit a lot of workload which loves more
resources such as memory bandwidth, caches.

Note this patch only handle the DT case.

V2:
fix commit log and loop more

  arch_topology: support for describing cache topology from DT
  arm64: Add complex scheduler level for arm64
