On the verge of applying this patch, looking deeper, I noticed
drivers/bus/ti-sysc.c managing the sysc controls. infact, I wonder if
b2745d92bb015cc4454d4195c4ce6e2852db397e ("bus: ti-sysc: Add support
for PRUSS SYSC type") could be merged with this?


Could you say why drivers/bus/ti-sysc.c would'nt be the right solution?

Ccying Kevin if he has any ideas about this.
