In the current boot, clients making use of the AB8500 sysctrl
may be probed before the ab8500-sysctrl driver. This gives them
-EINVAL, but should rather give -EPROBE_DEFER.Before this, the abx500 clock driver didn't probe properly,
and as a result the codec driver in turn using the clocks did
not probe properly. After this patch, everything probes
properly.Also add OF compatible-string probing. This driver is all
device tree, so let's just make a drive-by-fix of that as
well.Signed-off-by: Linus Walleij

The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config AB8500_CORE
drivers/mfd/Kconfig: bool "ST-Ericsson AB8500 Mixed Signal Power Management chip"...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.We replace module.h with init.h and export.h -- the latter since the file
does make use of EXPORT_SYMBOL.Signed-off-by: Paul Gortmaker

Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.Everything has been in linux-next for a while"

A check for a valid plat->sysctrl was introduced in:
2377e52 mfd: ab8500-sysctrl: Error check clean up
but the driver works just fine even without that initialization data,
and enforcing it breaks existing platforms for no reason.This patch removes the check and let the driver go ahead with probe.

AB8500 sysctrl driver implements a pm_power_off handler, but that is
currently not registered until a specific platform data field is
enabled.This patch drops the platform data field and always registers
ab8500_power_off if no other pm_power_off handler was defined before,
and also introduces the necessary cleanup code in the driver's remove

The abx500-clk driver is initiated at arch_initcall level. Moreover it
is relying on the ab8500-sysctrl API to be available. Therefore move
ab8500-sysctrl to arch_initcall level as well. The device is already
added before the abx500 clk device, thus it will be probed before as
well, which is exactly what we want.Signed-off-by: Ulf Hansson

This adds a pretty straight-forward system control driver for the
AB8500. This driver will be used from the core platform, e.g the
clock tree implementation in the machine code, and is by nature
singleton.There are a few simple functions to read, write, set and clear
registers so that the machine code can control its own foundation.Cc: Mattias Wallin
