ARM: at91/pio: add new PIO3 features
This patch adds the support for new PIO controller found on some at91sam SOCs. - more peripheral multiplexing - more features to configure on a PIO (pull-down, Schmitt trigger, debouncer) - support for several IRQ triggering features (type and polarity) Support for those new features are retrieved from the device tree compatibility string. Debugfs at91_gpio file is updated to monitor configuration. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
