Subject: [PATCH 7/7] mfd: exynos-lpass: Add runtime PM support
Date: Wed, 25 Jan 2017 12:50:31 +0100 [thread overview]
Message-ID: <1485345031-2948-8-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1485345031-2948-1-git-send-email-m.szyprowski@samsung.com>
Convert exisitng lpass-suspend/resume callbacks into runtime PM callbacks.
This way Exynos LPASS driver will be ready for use with power domains
enabled. LPASS will be runtime resumed/suspended as a result of its child
devices runtime PM transitions.
