commit ad1adb89a0d9410345d573b6995a1fa9f9b7c74a
(usb: musb: gadget: do not poke with gadget's list_head)
fixed a bug in musb where it was corrupting the list_head
which is supposed to be used by gadget drivers. While
doing that, I forgot to fix the usage in musb_gadget_dequeue()
method. Fix that.

For OMAP3 and OMAP4 for offmode and retention support, musb
sysconfig is configured to force idle and standby with ENABLE_FORCE bit
of OTG_FORCESTNDBY set.
And on wakeup configure to no ilde/standby with resetting the ENABLE_FORCE
bit. There is not need to save and restore of this register anymore
so removed omap2430_save_context/omap2430_restore_context functions.
and also removed otg_forcestandby member of musb_context_registers
structure

Powerdown the internal PHY during board init for OMAP44xx.
So that when musb is disabled core transition to retention/off

In OMAP3xxx with OTG mode or host only mode, When the device
is inserted after the gadget driver loading the enumeration was not
through. This is because the mentor controller will start sensing the
ID PIN only after setting the session bit.
So after ID-GND, need to set the session bit for mentor to get it
configured as A device.
This is a fix to set the session bit again in ID_GND notification handler.
Tested with OMAP3630Zoom3 platform.

add names to EHCI and OHCI resources. That will help us
identify the resource correctly when moving to a setup
where OHCI and EHCI play well together.

now that we have names on all memory bases, we can
switch to use platform_get_resource_byname() which
will make it simpler when we move to a setup where
OHCI and EHCI on OMAP play well together.

enabling and disabling the common clocks for ehci
and ohci is implemented. usbhs is a common parent
platform driver for EHCI and OHCI driver. This driver
receives the clock enable and disable requests
from ehci and ohci drivers.The UHH and TLL
initialization is also performed.

A new usbhs platform device is defined;
this device will be the parent device of ehci and
ohci platform devices. the usbhs_init function
is defined which does the usbhs device initialization
and I/O mux of ehci and ohci.

From: Keshava Munegowda <keshava_mgowda-l0cyMroinI0@public.gmane.org>
The ehci and ohci drivers are simplified; Since
UHH and TLL initialization, clock handling are
done by common usbhs core driver, these functionalities
are removed from ehci and ohci drivers.
