From 5fd9c05c846db98319e75496612da24435cee208 Mon Sep 17 00:00:00 2001
From: Geliang Tang <geliangtang@163.com>
Date: Fri, 8 Jan 2016 23:51:46 +0800
Subject: [PATCH] clk: move the common clock's to_clk_*(_hw) macros to
 clk-provider.h

to_clk_*(_hw) macros have been repeatedly defined in many places.
This patch moves all the to_clk_*(_hw) definitions in the common
clock framework to public header clk-provider.h, and drop the local
definitions.
