This is useful in virtualized or multi-domain environments where keyslot layout is partitioned (e.g., per-VM isolation). If the property is not present, the keyslot is used as-is (identity mapping). The binding is used by the exynos UFS driver to support secure inline encryption in domain-isolated scenarios.
