The only issue is that the gpios on the same "port" have restrictions on their status - they can only be enabled "all" or "none" for gpios that map to the same port. F.ex. gpio0, gpio32, gpio64 and gpio96 must all be enabled or disabled because at the hardware level you control the _port_.
This is fairly common. For example that an entire port/block share a clock.
But as I noted earlier, that could just be the driver enforcing this.
Yeps. Yours, Linus Walleij _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
