^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) Controls access arbitration for GPIO-based FSI master. A
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) value of 0 (the default) sets normal mode, where the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) driver performs FSI bus transactions, 1 sets external mode,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) where the FSI bus is driven externally (for example, by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) a debug device).
