What: /sys/bus/platform/devices/[..]/fsi-master-gpio/external_mode
Date: Feb 2018
KernelVersion: 4.17
Contact: jk@ozlabs.org
Description:
Controls access arbitration for GPIO-based FSI master. A
value of 0 (the default) sets normal mode, where the
driver performs FSI bus transactions, 1 sets external mode,
where the FSI bus is driven externally (for example, by
a debug device).
