[PATCH v8 1/7] interconnect: icc-clk: Allow user to specify master/slave ids

[Varadarajan Narayanan]

Presently, icc-clk driver autogenerates the master and slave ids.
However, devices with multiple nodes on the interconnect could
have other constraints and may not match with the auto generated
node ids. Hence, allow the driver to provide the preferred master
and slave ids.

v8: Per review feedback, set master/slave ids explicitly. Dont autogenerate
