clk: renesas: mstp: Keep wakeup sources active during system suspend
If a device is part of the CPG/MSTP 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. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org>
