From: Stephen Boyd Date: Wed, 1 Jun 2016 23:15:12 +0000 (-0700) Subject: clk: clps711x: Migrate to clk_hw based OF and registration APIs X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f48d947a162dfa9d62ebe6d79eb30100cb81751b;p=openwrt%2Fstaging%2Fblogic.git clk: clps711x: Migrate to clk_hw based OF and registration APIs Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs.
