[PATCH 0/3] of: Reimplement of_(bus_)?n_(size|addr)_cells()

[Rob Herring (Arm)]

This series reworks the of_(bus_)?n_(size|addr)_cells() functions. They 
fail to hold the DT spinlock while accessing 'parent' pointer and don't 
hold a reference to the parent node. Neither is likely a real issue as 
most nodes are static.

With these issues fixed, we can then replace the open coded version in 
of_irq_parse_raw().

This series depends on the fixes from this series[1].
