So how about just make it: int context_may_be_lost(struct device *dev); And then we can easily add more logic to it as needed for gpio-omap in addition to enable_off_mode. Regards, Tony

Add a quirk function to convey off mode state. This can be used to perform additional save/restore during off mode. Signed-off-by: Keerthy <j-keerthy@ti.com> --- arch/arm/mach-omap2/pdata-quirks.c | 6 ++++++ include/linux/platform_data/pinctrl-single.h | 1 + 2 files changed, 7 insertions(+)
