the MUSB IP is always OTG, so there's no point
in adding so many ifdefs on the code. Drop those
and always compile the driver for OTG support.
This also allows us to drop the useless "driver
mode" choice. For doing that, we need to make
musb depend on both Host and Peripheral side.

We have a generic way of enabling/disabling
different debug messages on a driver called
DYNAMIC_PRINTK. Anyone interested in enabling
just part of the debug messages, please read
the documentation under:
Documentation/dynamic-debug-howto.txt
for information on how to use that great
infrastructure.

Commit 3dacdf11 "usb: factor out state_string() on otg drivers"
broke building musb drivers since there is already another
otg_state_string() function in musb drivers, but with different
prototype. Fix musb drivers to use common otg_state_string(), too.
Also provide a nop for otg_state_string() if CONFIG_USB_OTG_UTILS
is not defined.

commit 4814ced511 (OMAP:
control: move plat-omap/control.h to mach-omap2/control.h)
moved <plat/control.h> to another location, preventing
drivers from accessing it, so we need to pass function
pointers from arch code to be able to talk to internal
PHY on AM35x.

instead of using musb_platform_suspend_resume,
we can use dev_pm_ops and let platform_device
core handle when to call musb_core's suspend and
glue layer's suspend.

musb core doesn't need to know about platform
specific details. So start moving clock
handling to platform glue layer and make
musb core agnostic about that.

that structure currently only holds a device
pointer to our own platform_device and musb's
platform_device, but soon it will hold pointers
to our clock structures and glue-specific bits
and pieces.

Just adding its own platform_driver, not really
using it yet.
When all HW glue layers are converted, more patches
will come to split power management code from musb_core
and move it completely to HW glue layer.

preparing to a big refactor on musb code. We need
to be able to compile in all glue layers (or at
least all ARM-based ones) together and have a
working binary.
While preparing for that, we move every glue
layer to export only one symbol, which is
a struct musb_platform_ops, and make all
other functions static.
Later patches will come to allow for compiling
all glue layers together and have a working
binary.

AM35x supports only 32bit read operations so we need to have
workaround for 8bit and 16bit read operations.

AM35x has musb interface and uses CPPI4.1 DMA engine.
Current patch supports only PIO mode. DMA support can be
added later once basic CPPI4.1 DMA patch is accepted.
Also added USB_MUSB_AM35X which is required to differentiate musb ips
between OMAP3x and AM35x. This config would be used to for below
purposes,
- Select am35x.c instead of omap2430.c for compilation
at drivers/usb/musb directory. Please note there are
significant differneces in these two files as musb ip
in quite different on AM35x.
Please note that in multi omap configuration only omap2430.c
file will get compiled and we would require to select only
AM35x based board config to compile am35x.c
- Select workaround codes applicable for AM35x musb issues.
one such workaround is for bytewise read issue on AM35x.
