Please use SET_SYSTEM_SLEEP_PM_OPS(). ?See <linux/pm.h>

We can use following macro to initialize .suspend and .resume callbacks.
But how do we initialize .runtime_suspend and .runtime_resume callbacks?

#define SIMPLE_DEV_PM_OPS(name, suspend_fn, resume_fn) \
const struct dev_pm_ops name = { \
? ? ? ? SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) \
}

Do we have something similar to following where we can assign separate
pair of callbacks?

SET_RUNTIME_PM_OPS()

Yes, I have done this way:

static const struct dev_pm_ops gpio_pm_ops = {
        SET_SYSTEM_SLEEP_PM_OPS(omap_gpio_suspend, omap_gpio_resume)
        SET_RUNTIME_PM_OPS(omap_gpio_runtime_suspend, omap_gpio_runtime_resume,
                                                                        NULL)

Perfect.
