JZ4740 USB Device Controller is not OTG compatible and does not have
DEVCTL register in silicon.

During ethernet-over-usb transactions, on reset, musb driver tries to
read from DEVCTL and consequently sets device as host (A-Device)
instead of peripheral (B-Device), which makes it a composite device to
the USB gadget driver.
This induces a kernel panic during power down where the USB gadget
driver does a null pointer dereference when trying to access the
composite device configuration.

On reset, do not rely on DEVCTL value for setting gadget peripheral
mode. Use is_otg flag instead to set it to B-Device.

Currently, resume and reset is completed when the USB core calls back
the root hub, asking for the port's state. This results in
unpredictable timing of state assertion, which in turn renders some
USB devices unusable after resume.

Fix this by moving the logic to end the reset and suspend state out of
musb_hub_control() into separate functions called from delayed workers.
GetPortStatus only reports the current state now, without taking any
real action.

The rh_timeout variable is kept in order to define a minimum time gap
between reset and resume only.

FWIW, in my case, a Verbatim "STORE N GO" mass storage device won't
resume cleanly without this patch.

USB remote wakeup using PHY wakeup is supported only in standby mode.
Enabling the PHY_WKUP will break DS0 mode of system suspend.
If the same is enabled while entering DS0, AM33xx never stays in DS0,
it returns immediately from DS0. By default make the PHY wakeup
disabled, using sysfs entry enable the same manually to get
the remote wakeup working from standby.

echo enabled > /sys/bus/platform/device/<usb phy id>/power/wakeup
This will enable the PHY wakeup while going to standby.

PHY wakeup feature is required to wakeup  the system from standby
state. Since AM33xx has a bug in which PHY wakeup should not
be enabled while entering DS0, disable the same by default.
A user wishing to use USB wakeup from standby mode need to enable
the same using the sysfs entries.

Also remove am335x_phy_runtime_(suspend/resume) this driver doesnot really
enable/disable the clocks to the PHY.
Add am335x_phy_(suspend/resume) and use the same for enabling the PHY_WKUP.

In the nokia gadget some USB functions (obex 1 and 2, phonet) are optional.

If at the start of nokia_bind_config e.g. fi_phonet is an error pointer,
which can happen because we don't fail the bind process if
usb_get_function_instance() fails for fi_phonet, then f_phonet is NULL, and

phonet_stat = usb_add_function(c, f_phonet);

is never called and phonet_stat remains 0.

If, in these circumstances, we hit the err_conf label then !phonet_stat
evaluates to true and we try usb_remove_function() with its second
parameter being f_phonet which is NULL and it causes NULL pointer
dereference.

This patch changes the initial values of (obex1|obex2|phonet)_stat to a
nonzero value so that if the err_conf label is hit while the respective
functions have not been acquired the usb_remove_function() is not called
for those functions.

This patch adds "maxpacket_limit" to struct usb_ep. This field contains
maximum value of maxpacket supported by driver, and is set in driver probe.
This value should be used by autoconfig() function, because value of field
"maxpacket" is set to value from endpoint descriptor when endpoint becomes
enabled. So when autoconfig() function will be called again for this endpoint,
"maxpacket" value will contain wMaxPacketSize from descriptior instead of
maximum packet size for this endpoint.

For this reason this patch adds new field "maxpacket_limit" which contains
value of maximum packet size (which defines maximum endpoint capabilities).
This value is used in ep_matches() function used by autoconfig().

Value of "maxpacket_limit" should be set in UDC driver probe function, using
usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function
set choosen value to both "maxpacket_limit" and "maxpacket" fields.

This patch modifies UDC drivers by adding support for maxpacket_limit.
