* gpio: grgpio: Staticize local symbolsSachin Kamat2013-06-191-3/+3
| | | | | | | | Local symbols accessed only in this file are made static. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Acked-by: Andreas Larsson <andreas@gaisler.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: grgpio: Add irq supportAndreas Larsson2013-04-261-3/+359
| | | | | | | | | | The drivers sets up an irq domain and hands out unique irqs to irq capable gpio lines regardless of how underlying irq maps to gpio lines. Any gpio line can map to any one or none of the irqs of the core, independently of each other.
