OMAP4430 supports UTMI and ULPI types of transceiver interface.
In UTMI mode: The PHY is embedded within OMAP4430. 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.
musb driver is register for blocking notifications from the transceiver
driver to get the event notifications for connect/disconnect and ID-GND.
Based on these events call the transceiver init/shutdown function to
configure the transceiver to toggle the VBUS valid, session end and ID_GND
signals to musb and power on/off the internal PHY.
For ID_GND event notifications, toggle the ID_GND signal and then wait for
musb to be configured as "A" device, and then call the transceiver function
to set the VBUS.
In OTG mode and musb as a host, When the Micro A connector used, VBUS is turned on
and session bit set. When the device is connected, enumeration goes through.
When the device disconnected from the other end of the connector(ID is still grounded),
link will detect the disconnect and end the session. When the device is connected back,
there are no events generated in the TWL6030-usb, and link is already down.
So the device is not detected. Removed the session bit disable code which
will recognize the connect of the device.
Limitation: In OTG host mode, if device is connected during boot, it does not get
detected. If disconnect and connect it back or connect after boot only it works.
Fix for this, I will submit seperate patch later.

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.

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.

Soon resource data will get automatically
populated from a set of autogenerated data
from TI's hardware database for the OMAP
platform.
Such database, might not have resources at
the expected order by the current drivers.
While we could hack in some exceptions to
that tool to generate resources in a specific
order, it seems less fragile to use the
resource name instead. That way, no matter
what order the resources are generated, the
driver still work.
Modified the OMAP, Blackfin and Davinci
architecture files to add the name of the IRQs
in the resource structures and musb driver to
use the platform_get_irq_byname() api to get
the device and dma irq numbers instead of using
the index.

The Inventra DMA engine used with the MUSB controller in many
SoCs cannot use DMA for control transfers on EP0, but can use
DMA for all other transfers.
The USB core maps urbs for DMA if hcd->self.uses_dma is true.
(hcd->self.uses_dma is true for MUSB as well).
Split the uses_dma flag into two - one that says if the
controller needs to use PIO for control transfers, and
another which says if the controller uses DMA (for all
other transfers).
Also, populate this flag for all MUSB by default.
(Tested on OMAP3 and OMAP4 boards, with EHCI and MUSB HCDs
simultaneously in use).

If RXCSR_AUTOCLEAR flag is not cleard before PIO reading, one packet
may be recieved by musb fifo, but no chance to notify
software, so cause packet loss, follows the detailed process:
- PIO read one packet
- musb fifo auto clear the MUSB_RXCSR_RXPKTRDY
- musb continue to recieve the next packet, and MUSB_RXCSR_RXPKTRDY
is set
- software clear the MUSB_RXCSR_RXPKTRDY, so there is no chance for
musb to notify software that the 2nd recieved packet.
The patch does fix the g_ether issue below:
- use fifo_mode 3 to enable double buffer
- 'ping -s 1024 IP_OF_BEAGLE_XM'
- one usb packet of 512 byte is lost, so ping failed,
which can be observed by wireshark
note:
Beagle xm takes musb rtl1.8 and may fallback to pio mode
for unaligned buffer.

Buffer is mapped to dma when dma channel is
allocated. If, for some reason, dma channel
programming fails, musb code will fallback
to PIO mode to transfer that request. In
that case, we need to unmap the buffer
back to CPU.
MUSB RTL1.8 and above cannot handle buffers
which are not 32bit aligned. That happens to
every request sent by g_ether gadget
driver. Since the buffer sent was unaligned,
we need to fallback to PIO.
Because of that, g_ether was failing due
to missing buffer unmapping.
With this patch and [1] g_ether works fine
with all MUSB revisions.
Verified with OMAP3630 board, which has
MUSB RTL1.8 using g_ether and g_zero.

The Inventra DMA engine in version 1.8 and later of the MUSB
controller cannot handle DMA addresses that are not aligned
to a 4 byte boundary. It ends up ignoring the last two bits
programmed in the DMA_ADDR register. This is a deliberate
design change in the controller and is documented in the
programming guide.
Earlier versions of the controller could handle these
accesses just fine.
Fail dma_channel_program if we see an unaligned address when
using the newer controllers, so that the caller can carry out
the transfer using PIO mode.
(Current callers already have this backup path in place).

musb_gadget_queue() checks for '!req->buf' condition twice:
in the second case the code is both duplicated and unreachable
as the first check returns early.

musb driver still may write MUSB_DEVCTL register after clock is disabled
in musb_platform_exit, which may cause the kernel oops[1] when musb_hdrc
module is loaded for the 2nd time.
The patch fixes the kernel oops in this case.

Split the USB MMR init steps out into a helper func that both the platform
init and the resume code may call.
Then while suspending, the gpio_vrsel will change from high to low which
will generate a wakeup event and resume the system immediately, so we need
to manually drive it low before we sleep.
