OMAP3: GPIO fixes for off-mode
Off mode is now using the omap2 retention fix code for scanning GPIOs during off-mode transitions. All the *non_wakeup_gpios variables are now used for off-mode transition tracking on OMAP3. This patch fixes cases where GPIO state changes are missed during off-mode. Signed-off-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
