From a1bbd630710d5da89a9c347c84d7badd30e7e68a Mon Sep 17 00:00:00 2001

Subject: [PATCH 034/102] soc: mediatek: PMIC wrap: split SoC specific init
into callback
This patch moves the SoC specific wrapper init code into separate callback
to avoid pwrap_init() getting too large. This is done by adding a new
element called init_special to pmic_wrapper_type. Each currently supported
SoC gets its own version of the callback and we copy the code that was
previously inside pwrap_init() to these new callbacks. Finally we point the
2 instances of pmic_wrapper_type at the 2 new functions.
