[GIT PULL v2] of: Add of-graph helpers to loop over endpoints and find ports by id

[Philipp Zabel]

Hi Grant, Rob,

this series has been around for quite some time now, basically unchanged
except for adding fixes for new users of the API that keep appearing
over time in different subsystems.

It would be really helpful to get this merged for v4.0. Could you still
make this happen?

Alternatively, could I please get your ack to allow this tag to be
merged into the other subsystem trees for v4.1 so that patches that
depend on it don't have to wait for yet another merge window?

best regards
Philipp

----------------------------------------------------------------
of: Add of-graph helpers to loop over endpoints and find ports by id

This series converts of_graph_get_next_endpoint to decrement the
refcount of
the passed prev parameter. This allows to add a
for_each_endpoint_of_node
helper macro to loop over all endpoints in a device tree node.
The of_graph_get_port_by_id function is added to retrieve a port by its
known
port id (contained in the reg property) from the device tree.
