Rafael J. Wysocki 8b258cc8ac PM Sleep: Do not extend wakeup paths to devices with ignore_children set ... Commit 4ca46ff3e0 (PM / Sleep: Mark devices involved in wakeup signaling during suspend) introduced the power.wakeup_path field in struct dev_pm_info to mark devices whose children are enabled to wake up the system from sleep states, so that power domains containing the parents that provide their children with wakeup power and/or relay their wakeup signals are not turned off. Unfortunately, that introduced a PM regression on SH7372 whose power consumption in the system "memory sleep" state increased as a result of it, because it prevented the power domain containing the I2C controller from being turned off when some children of that controller were enabled to wake up the system, although the controller was not necessary for them to signal wakeup. To fix this issue use the observation that devices whose power.ignore_children flag is set for runtime PM should be treated analogously during system suspend. Namely, they shouldn't be included in wakeup paths going through their children. Since the SH7372 I2C controller's power.ignore_children flag is set, doing so will restore the previous behavior of that SOC. Signed-off-by: Rafael J.
