From: Sascha Hauer Date: Fri, 22 Jan 2016 12:39:25 +0000 (+0100) Subject: soc: mediatek: SCPSYS: Fix double enabling of regulators X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cc8ed76938b5cf6a54ab3d60edabaf808dc960d1;p=openwrt%2Fstaging%2Fblogic.git soc: mediatek: SCPSYS: Fix double enabling of regulators With CONFIG_PM enabled do not call genpd->power_on manually as this will cause the regulators being turned on once in SCPSYS probe and then again when the genpd core turns on the domains. Instead, call genpd->power_on only with CONFIG_PM disabled and tell the genpd core that the domains are disabled when registered.
