This series (on top of current char-misc-next) implements "external
mode" (ie, support for FSI debug devices) for the GPIO-based FSI master
driver.
We implement this control in the GPIO master driver, as it has the
mapping of raw GPIO pins to fsi control signals, and provides a
mechanism for the kernel to retain exclusive access to those GPIOs.
Cheers,
Jeremy
