From 390403fd79821bbd0c3a0d83307df2be87047b36 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 10 Apr 2014 11:01:09 -0700 Subject: ARM: OMAP3: PM: remove access to PRM_VOLTCTRL register There is a solitary write to this register every wakeup from off-mode, which isn't doing anything, so remove it. Also note that modifying this register trashes any attempted voltage scaling configuration and the change probably should never have gotten merged in the first place.

This does not work currently for GPMC when booted in device tree mode as it attempts to remap the the allocated GPMC partition to the address configured by the device tree plus the device offset. Note that this works just fine when booted with legacy mode. Let's fix the issue by just ignoring any device specific offset while remapping. And let's make sure the remap address confirms to the GPMC 16MB minimum granularity as listed in the TRM for GPMC_CONFIG7 BASEADDRESS bits.
