[PATCH 0/2] gpio: of: Support cascaded GPIO

[Pantelis Antoniou]

These two patches enable GPIO cascades where a match may be
retried until the finalr real GPIO is located.

The first patch removes the const specifier from gpiospec at of_xlate(),
while the second introduces the new method of_gpiochip_find() that
performs the cascade operation.
