From 7aff266552d6042b43d3d5a9b13f0009ef862033 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 13 Oct 2017 14:24:22 +0200 Subject: clk: renesas: cpg-mssr: Keep wakeup sources active during system suspend If a device is part of the CPG/MSSR Clock Domain and to be used as a wakeup source, it must be kept active during system suspend. Currently this is handled in device-specific drivers by explicitly increasing the use count of the module clock when the device is configured as a wakeup source. However, the proper way to prevent the device from being stopped is to inform this requirement to the genpd core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag. Note that this will only affect devices configured as wakeup sources.
