Subject: Re: [PATCH] pio: add arch specific gpio_is_valid() function
Date: Mon, 6 Sep 2010 19:23:22 -0700 (PDT) [thread overview]
Message-ID: <280328.53116.qm@web180311.mail.gq1.yahoo.com> (raw)
In-Reply-To: <20100903164158.GH17702@game.jcrosoft.org>
Still not liking or accepting this proposed
change to the GPIO framework.
For the AT91 case (where integers 0..N are
IRQs, but N..max are GPIOs)
A simpler solution is just to use a bit in
the integer to indicate IRQ vs GPIO. Like
maybe the sign bit.. which is never set on
valid GPIO numbers, but platforms could let
be set on IRQs.
