0d15463c05 dtoc: Rename the phandle struct
Rather than naming the phandle struct according to the number of cells it
uses (e.g. struct phandle_2_cell) name it according to the number of
arguments it has (e.g. struct phandle_1_arg). This is a more intuitive
naming.

2cce586651 dtoc: Support multiple compatible strings in a node
Sometimes a node will have multiple compatible strings. Drivers may use
one or the other so the best approach seems to be to #define them to be
equivalent.

Update dtoc to support this.

e160f7d430 dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

1269625177 dm: Update the of-platdata README for the new features
Revise the content based on the v2 additions. This is kept as a separate
patch to avoid confusing those who have already reviewed the v1 series.
