This patch completes commit 08406f5 by fixing the following issues, according to
the reference manual:
* MXC_OTG_UCTRL_OPM_BIT disables (masks) the power/oc pins if set, like H1PM and
H2PM, not the opposite.
* MXC_OTG_PHYCTRL_OC_DIS_BIT disables the oc pin if set, like H1_OC_DIS, not the
opposite.
* Typos in comments.

The EHCI driver is not stable enough to be enabled by default. In v3.5,
it has at least the following problems:
- warning dump during bootup
- hang during suspend
- prevents CORE powerdomain from entering retention during idle (even
when no USB devices connected.)
This demonstrates that this driver has not been thoroughly tested and
therfore should not be enabled in the default defconfig.
In addition, the problems above cause new PM regressions which need be
addressed before this driver should be enabled in the default
defconfig.

As the AB8500 is a subordinate MFD device to the DB8500-PRCMU,
for consistency and a better 1:1 depiction of how the hardware
is laid out, it is a good idea to register it in the same way
as we do for the other MFD child devices. In order for us to do
this successfully we have to pass AB8500's platform data when
registering the DB8500-PRCMU from platform code.
Also solves this issue:
WARNING: at fs/sysfs/dir.c:526 sysfs_add_one+0x88/0xb0()

Add irq domain support for max8997 interrupts. The reverse mapping method
used is linear mapping since the sub-drivers of max8997 such as regulator
and charger drivers can use the max8997 irq_domain to get the linux irq
number for max8997 interrupts. All uses of irq_base in platform data and
max8997 driver private data are removed.

Hierarchically, the AB8500 is a child of the DB8500 PRCMU. So now that
Device Tree is being used and MFD core code is Device Tree aware, we
can simply register DB8500 PRCMU from Device Tree in the normal way
then allow the DB8500 PRCMU driver to register the AB8500 as a simple
MFD device at probe time.

Al has some fixes, we have some concerns with Al's patches but we've

This will allow almost complete removal of all non-DT board files in v3.7.
* Other miscellaneous changes.

When pin control mapping tables are written the registered device
name is supplied for use in name-based searches within the pinctrl
driver. In the case of the DB8500 the string "pinctrl-db8500" is
used. However, when we register the driver with Device Tree, its
naming convention uses something that looks more like "pinctrl.2".
To work around the device naming inconsistencies between devices
registered via platform code and the ones registered by Device
Tree, we use AUXDATA to over-ride the Device Tree naming scheme.

We can control renesas_usbhs driver as 2 way which are
autonomy mode and external IRQ trigger mode.
Autonomy mode is very easy settings for platform,
but it required USB power domain always ON,
since its connection/disconnection IRQ come from it.
If platform uses external IRQ trigger mode,
USB power domain can be OFF, since its
connection/disconnection IRQ come from external IRQ.
This patch enable external IRQ mode.
Now it is possible to add USB support on A4SP domain.
