5*4882a593SmuzhiyunDescription:
6*4882a593Smuzhiyun                Controls access arbitration for GPIO-based FSI master. A
7*4882a593Smuzhiyun		value of 0 (the default) sets normal mode, where the
8*4882a593Smuzhiyun		driver performs FSI bus transactions, 1 sets external mode,
9*4882a593Smuzhiyun		where the FSI bus is driven externally (for example, by
10*4882a593Smuzhiyun		a debug device).
