This implements various helpers to support OF bindings for the GPIO LIB API. Previously this was PowerPC specific, but it seems this code isn't arch-dependent anyhow, so let's place it into of/. SPARC will not see this addition yet, real hardware seem to not use GPIOs at all. But this might change: http://www.leox.org/docs/faq_MLleon.html "16-bit I/O port" sounds promising. :-) Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
