From: Christopher Bostic <cbostic@linux.vnet.ibm.com>
Add an optional FSI master property 'no-scan-on-init. This can be specified to indicate that a master should not be automatically scanned at init time. This is required in cases where a scan could interfere with another FSI master on the same bus.
