From 35d7dccc74184bdead550e6633636504539a0105 Mon Sep 17 00:00:00 2001
From: Tomasz Figa <t.figa@samsung.com>
Date: Fri, 23 Aug 2013 19:09:41 +0200
Subject: [PATCH 0584/1302] clk: max77686: Refactor driver data handling
As a prerequisite for further patch adding OF clock provider support to
the driver, this patch changes the driver to store an array of struct
clk * as driver data.
