The sad fact is that removal of pm_genpd_dev_need_restore() calls from arch/arm/mach-exynos/pm_domains.c introduces regressions in multiple exynos drivers (I'm sure it breaks media drivers). I think before doing such changes all relevant drivers should be updated first. I need to take a closer look again, but it seems after dropping the pm_genpd_dev_need_restore() calls, client driver's runtime_resume() callback is not being called in response to first pm_runtime_get(_sync) call, even if a device is runtime pm active. More details can be found in commit ebc35c726298ba3fdebba316a 'ARM: EXYNOS: register devices in 'need_restore' state for pm_domains'. The above only happens when devices are added to an inactive power domain, then I guess patch 2/4 is also an attempt to address this issue ? -- Thanks, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
