In order to provide per-user accounting, this separates the struct clk
used in the common clock framework into two structures 'struct clk_core'
and 'struct clk'.  struct clk_core will be used for internal
manipulation and struct clk will be used in the clock API
implementation.

In this patch, struct clk is simply renamed to struct clk_core and a new
struct clk is implemented which simply wraps it.  In the next patch, the
new struct clk will be used to implement per-user clock enable
accounting.

There is a rather hacky #define of clk_core to clk for the non-common
clk case in order to avoid a mass rename of all clk non-common clk
implementations.

Hi Rabin,

I reviewed it with help of git diff --word-diff and didn't found any silly
mistake in the replacement of clk with clk_core :)

diff --git a/drivers/clk/clk-core.h b/drivers/clk/clk-core.h
+#ifdef CONFIG_COMMON_CLK
+#define clk_to_clk_core(clk)   ((struct clk_core *)(clk))
+#define clk_core_to_clk(core)  ((struct clk *)(core))
+#else
+#define clk_to_clk_core(clk)   ((clk))
+#define clk_core_to_clk(core)  ((core))

Isn't something wrong here? For common clk case shouldn't
this be:
+#define clk_to_clk_core(clk)  (&clk->clk)
+#define clk_core_to_clk(core) (container_of(clk, ...))  //not getting into the exact format here
Sorry, if i am missing basics.
