From ac269395cdd80b9b088d9b5306015bd4b8bc176d Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 30 Jul 2015 17:20:57 -0700 Subject: [PATCH] clk: qcom: Convert to clk_hw based provider APIs We're removing struct clk from the clk provider API, so switch this code to using the clk_hw based provider APIs.
