[PATCH 5.15 331/913] soc: mediatek: pm-domains: Add wakeup capacity support in power domain

[Greg Kroah-Hartman]

From: Chun-Jie Chen <chun-jie.chen@xxxxxxxxxxxx>

[ Upstream commit ac0ca395543af061f7ad77afcda0afb323d82468 ]

Due to some power domain needs to keep on for wakeup in system suspend,
so add GENPD_FLAG_ACTIVE_WAKEUP support in Mediatek power domain driver.

Fixes: 59b644b01cf4 ("soc: mediatek: Add MediaTek SCPSYS power domains")
