In commit 001dd84 ("usb: musb: start musb on the udc side, too") it was
ensured that the state engine is started also in OTG mode after a
removal / insertion of the gadget.
Unfortunately this change also introduced a bug: If the device is
configured as OTG and it connected with a remote host _without_ loading
a gadget then we bug() later (because musb->otg->gadget is not
initialized).
Initially I assumed it might be nice to have the host part of musb in
OTG mode working without having a gadget loaded. This bug and fact that
it wasn't working like this before the host/gadget split made me realize
that this was a silly idea.
This patch now introduces back the old behavior where in OTG mode the
host mode is only working after the gadget has been loaded.

After commit 09fc7d22b0 (usb: musb: fix incorrect
usage of resource pointer), CPPI DMA driver on DaVinci DM6467 can't detect its
dedicated IRQ and so the MUSB IRQ is erroneously used instead. This is because
only 2 resources are passed to the MUSB driver from the DaVinci glue layer, so
fix this by always copying 3 resources (it's safe since a placeholder for the
3rd resource is always there) and passing 'pdev->num_resources' instead of the
size of musb_resources[] to platform_device_add_resources().

This is what I observe:
On the first connect, the musb starts with DEVCTL.Session set. On
disconnect, musb_core calls try_idle. That functions removes the Session
bit signalizing that the session is over (something that only in OTG is
required). A new device, that is plugged, is no longer recognized.
I've setup a timer and checked the DEVCTL register and I haven't seen a
change in VBus and I saw the B-Device bit set. After setting the IDDIG
into A mode and forcing the device to behave like a A device, I didn't
see a change.
Neither VBUS goes to 0b11 nor does a session start request comes.
In the TI-v3.2 kernel they skip to call musb_platform_try_idle() in the
OTG_STATE_A_WAIT_BCON state while not in OTG mode.
Since the second port hast a standard A plug the patch changes the port
to run in host mode only and skips the timer which would remove
DEVCTL.Session so we can reconnect to another device later.

This driver is currently used by musb' cppi41 couter part. I may merge
both dma engine user of musb at some point but not just yet.
The driver seems to work in RX/TX mode in host mode, tested on mass
storage. I increaed the size of the TX / RX transfers and waited for the
core code to cancel a transfers and it seems to recover.
v2..3:
- use mall transfers on RX side and check data toggle.
- use rndis mode on tx side so we haveon interrupt for 4096 transfers.
- remove custom "transferred" hack and use dmaengine_tx_status() to
compute the total amount of data that has been transferred.
- cancel transfers and reclaim descriptors
v1..v2:
- RX path added
- dma mode 0 & 1 is working
- device tree nodes re-created.

This moves the two instances from the big node into two child nodes. The
glue layer ontop does almost nothing.
There is one devices containing the control module for USB (2) phy,
(2) usb and later the dma engine. The usb device is the "glue device"
which contains the musb device as a child. This is what we do ever since.
The new file musb_am335x is just here to prob the new bus and populate
child devices.
There are a lot of changes to the dsps file as a result of the changes:
- musb_core_offset
This is gone. The device tree provides memory ressources information
for the device there is no need to "fix" things
- instances
This is gone as well. If we have two instances then we have have two
child enabled nodes in the device tree. For instance the SoC in beagle
bone has two USB instances but only one has been wired up so there is
no need to load and init the second instance since it won't be used.
- dsps_glue is now per glue device
In the past there was one of this structs but with an array of two and
each instance accessed its variable depending on the platform device
id.
- no unneeded copy of structs
I do not know why struct dsps_musb_wrapper is copied but it is not
necessary. The same goes for musb_hdrc_platform_data which allocated
on demand and then again by platform_device_add_data(). One copy is
enough.

lguest: fix CONFIG_PAE -> CONFIG_x86_PAE in comment
...
These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
have these changes merged through arm-soc. As we proceed to untangle
the dependencies between platform code and driver code, the amount of
changes in this category is fortunately shrinking, for 3.11 we have
16 branches here and 101 non-merge changesets, the majority of which
are for the stedma40 dma engine driver used in the ux500 platform.
Cleaning up that code touches multiple subsystems, but gets rid
of the dependency in the end.
The mailbox code moved out from mach-omap2 to drivers/mailbox
is an intermediate step and is still omap specific at the moment.
Patches exist to generalize the subsystem and add other drivers
with the same API, but those did not make it for 3.11.
Conflicts:
* In cpu-db8500.c results from the removal of the u8500_of_init_devices
function in combination with the split of u8500_auxdata_lookup.
* In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.
