[PATCH] Add system-cache-controller to the list of generic node names

[PATCH] Add system-cache-controller to the list of generic node names

[Sai Prakash Ranjan]

System Cache Controller (Last Level Cache Controller/LLCC) does not
have a cache-level associated with it as enforced by the already
existing 'cache-controller' node name, so add system-cache-controller
to the list of generic node names as decided on the lkml in [1][2]
and already being used in the dts for sometime now.

I don't want to encourage others to use this over 'cache-controller'

Right, but why would others use this over cache-controller? This is 
supposed
to be used only for last level cache controllers where there is no 
cache-level
associated with it like in the system cache controller/LLCC found in QTI 
SoCs.
Also you had acked the corresponding change in the DT binding for LLCC 
[1].

I don't agree there's never a level.

Using the cache binding will be necessary if you want to populate the
kernel's cache info. If your caches have MPAM support, they are going
to need to follow the cache binding as well.

Yes, but that doesn't mean it belongs in the spec. Maybe when we have
more than 1 case that will change, but for now I don't think it should
be in the spec.
