+From 45ead148322ba7be9de970a2ab6be4ed3f7ca184 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 33/53] soc: mediatek: PMIC wrap: add wrapper callbacks for
+ init_reg_clock
+
+Split init_reg_clock up into SoC specific callbacks. The patch also
+reorders the code to avoid the need for callback function prototypes.
