Subject: [PATCH v9 2/5] clk: samsung: Add support for runtime PM
Date: Mon, 21 Aug 2017 10:05:00 +0200	[thread overview]
Message-ID: <1503302703-13801-3-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1503302703-13801-1-git-send-email-m.szyprowski@samsung.com>

This patch adds struct device pointer to samsung_clk_provider and forwarding it
to clk_register_* functions, so drivers can register clocks, which use runtime
pm feature.
