Adding the twl6030-usb transceiver support for OMAP4 musb driver.

OMAP4 supports 2 types of transceiver interface.

1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality
is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin
sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY
functionality is embedded within the OMAP4430.

There is no direct interactions between the MUSB controller and TWL6030
chip to communicate the session-valid, session-end and ID-GND events.
It has to be done through a software by setting/resetting bits in
one of the control module register of OMAP4430 which in turn toggles
the appropriate signals to MUSB controller.

The internal transceiver has functional clocks and
powerdown bits to powerdown the PHY for power saving.

Since there is no option available for having 2 transceiver drivers
for one USB controller, internal PHY specific APIs are passed through
plaform_data function pointers to use in the twl6030-usb transceiver
driver.

2. ULPI interface is provided for off-chip transceivers.

With TWL6030-usb, VBUS SESS_VLD and SESS_END events are not generated
as expected. When these interrupts are enabled, charger VBUS detection
interrupt does not get generated. So USBOTG has to be dependent on charger
VBUS interrupts.
So added one bit for USBOTG and changed the handler to call the
USBOTG handler whenever there is a charger VBUS interrpt.

VBUS SESS_VLD and SESS_END event generation issue is under debug with
HW team. This fix might not be required once after fixing the issue.

all glue layers are now fully moved to the
new setup. We are now using dev_pm_ops to
implement suspend/resume functionality and
thus, musb_platform_suspend/resume has become
deprecated and useless.

This patch drops those function pointers and
its uses.
Signed-off-by: NFelipe Balbi <balbi@ti.com>

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.

useless for us. Drop it.

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.

moving clock handling to platform glue

We will call glue layer drivers musb-<glue layer>,
so in order to keep things somewhat standard, let's
change the underscore into a dash.

This will make things simpler when choosing which
glue layer to compile. It avoids a lot of magic
around the "default" Kconfig option and lets the

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.

This will be passed to musb_core by platform glue
layer in order to make it easier to compile support
for several HW glue layers.

Later patches will come using this structure and
also moving HW glue layers to its own platform
driver; the idea is to be able to handle platform
peculiarities in a manner which doesn't affect one
another.
