This series introduces interconnect debugfs files that support voting for any path the framework supports.
We've historically relied on an out-of-tree module for this, which used the old icc_get() that was recently removed in [0]. The old icc_get() took integer endpoint IDs, which made identifying paths in our old implementation non-intuitive. The logical node names typically don't change much chip-to-chip, but the raw integer IDs do. Take this opportunity to introduce an icc_get() that uses string names instead, which allows for a more intuitive and generic debugfs interface.
We rely on this support for debug, test, and verification. Hopefully it'll be useful for other vendors as well.
