I'm good with this, so: Reviewed-by: Doug Anderson <diand...@chromium.org> To address Bartlomiej: =m is what's in ChromeOS for exynos, though I notice that other platforms in the ChromeOS tree have =y. I'm not sure why there is a difference, but it's probably just carelessness. Normally in ChromeOS we use "=m" for drivers that can afford to wait until after the UI is up and running. That helps improve boot time since the user can use the device sooner (and it's OK if the battery driver takes a few extra seconds to load). The only things that really should be "=y" are drivers that are critical to load early or that are needed for the user to interact with the system. In this case you could argue that loading sbs earlier means that if the system is low on battery it will get back to "shutdown" sooner. I'm not sure getting the shutdown a few seconds earlier is really critical, though... -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
