This is only used by omap1.
And to fix things properly, this should not be included
from the drivers at all.

We are moving omap2+ to use the device tree based pinctrl-single.c
and will be removing the old mux framework. This will remove the
omap1 specific parts from plat-omap.

TIF_NOTIFY_RESUME will work in precisely the same way; all that
is achieved by TIF_IRET is appearing that there's some work to be

Amend the PL022 pin controller to optionally take a pin control
handle and set the state of the pins to "default" on boot and
runtime resume, and to "sleep" at runtime suspend. This way we
will dynamically save power on the SPI busses, for example some
electronic designs may be able to ground the pins when unused
instead of pull-up. Some pin controllers may want to set the
pins as wake-up sources when sleeping.
Effect on platforms using the PL022 driver:
- If the platform does not use pin control - no semantic effect,
the pinctrl stubs will kick in and resolve the situation.
- Platforms using this driver and have pin control but no
function defined for the PL022 need to either supply a
"default" function in their map or enable pinctrl dummies
so the driver is satisfied.
- Platforms using this driver with hogs for setting up the PL022
pin control - stop using hogs to take the pl022 pin control
handle, let the driver handle this.
I'be looked at some platforms that may be affected:
- SPEAr: appears to define the proper functions in their device
trees and not hogging them, so things should be smooth, the
driver will simply start to take its pins.
- Ux500: the proper function is defined and will be taken properly
by the driver. New sleep states introduced by a separate patch to
ux500 but no regression, since the default state is sufficient.
- U300: old hog deleted as part of this patch.
- LPC32xx: does not appear to be using pinctrl.
- ARM Integrator IMPD1, RealView & Versatile: does not use pinctrl.

Card Detection GPIO on the HREF is located on the tc3598x-gpio
expander.

Since initial support was provided for the Nomadik I2C driver, it
has been converted to an AMBA device. AMBA devices are probed in
a slightly different way to other devices, so we have to identify
them using an "arm,primecell" compatible string. As well as doing
just that, this patch specifies which regulators the controller
should use and requests a clock-speed. The latter is provided as
more of an example, as it's the same as the recently changed
default configuration.
