From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> Changes in v2: [By Ulf Hansson] - I have picked up the series from Geert [1] and converted it into use the WAKEUP_PATH driver PM flag. This includes some minor changes to each patch and updates to the changelogs. - An important note, the WAKEUP_PATH driver PM flag is introduced in a separate series [2], not yet applied, so @subject series depends on it. - One more note, two of the patches has a checkpatch error, however I did not fix them, becuase I think that should be done separate.

Kind regards Uffe Hi all, If an interrupt controller in a Renesas ARM SoC is part of a Clock Domain, and it is part of the wakeup path, it must be kept active during system suspend. Currently this is handled in all interrupt controller drivers by explicitly increasing the use count of the module clock when the device is part of the wakeup path. However, this explicit clock handling is merely a workaround for a failure to properly communicate wakeup information to the device core. Hence this series fixes the affected drivers by setting the devices' power.wakeup_path fields instead, to indicate they are part of the wakeup path. Depending on the PM Domain's active_wakeup configuration, the genpd core code will keep the device enabled (and the clock running) during system suspend when needed. Note that most of these patches depend on the series "[PATCH v2 0/3] PM / Domain: renesas: Fix active wakeup behavior", hence they should not be applied yet. This has been tested on r8a73a4/ape6evm, r8a7740/armadillo, r8a7791/koelsch, r8a7795/salvator-x and -xs, r8a7796/salvator-x, and sh73a0/kzm9g. Thanks for your comments!
