Subject: ARM: S3C64XX: Initial support for Wolfson/Simtec Cragganmore/Banff

The Cragganmore carrier card and Banff CPU module are used on Wolfson
Microelectronics reference systems.  This initial support covers the
core system which is a fairly generic S3C6410 based design, further
patches will add support for the key features of the reference system.

The initial board bringup and therefore much of the key code was done by
Ben Dooks for Simtec, with additional work (especially around the
integration of the Wolfson devices) being done by myself.

From ae24c263271ea450df8af331c0ec34ff3086c962 Mon Sep 17 00:00:00 2001
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
Date: Wed, 22 Jun 2011 13:08:13 +0900
Subject: ARM: S3C64XX: Refresh Cragganmore support

The original Cragganmore code was submitted while new code was being
refused for mainline. This patch was unexpectedly merged upstream but
development had continued in the expectation that the code would be
resubmitted later so no split patches were maintained. This patch
synchronises that work with the recently merged driver.

The main changes are fleshing out of the PMIC and audio integration for
the system, including addition of the Dallas Dhu and Tobermory audio
modules, plus some minor updates to account for revision 2 hardware.

Subject: ARM: S3C64XX: Configure supplies for all Cragganmore regulators

All the regulators on the system are supplied from the fixed wall supply.
While there's no functional value in telling the regulator core this it
does ensure that as a regulator maintainer I'll be exercising the supply
logic frequently.
