From 944b9a41e004534f3634335aa1d6bec16700028f Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 1 Jun 2016 16:15:15 -0700 Subject: [PATCH] clk: ls1x: 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.
