- Select am35x.c instead of omap2430.c for compilation

Please note that in multi omap configuration only omap2430.c

AM35x based board config to compile am35x.c
- Select workaround codes applicable for AM35x musb issues.

may as well do so.
This patch (as1432) softens our acceptance criterion by allowing

This commit implements port remote wakeup.
When a port is in U3 state and resume signaling is detected from a device,
the port transitions to the Resume state, and the xHC generates a Port Status
Change Event.
For USB3 port, software write a '0' to the PLS field to complete the resume
signaling. For USB2 port, the resume should be signaling for at least 20ms,
irq handler set a timer for port remote wakeup, and then finishes process in
hub_control GetPortStatus.
Some codes are borrowed from EHCI code.

Add software trigger USB device suspend resume function hook.
Do port suspend & resume in terms of xHCI spec.
Port Suspend:
Stop all endpoints via Stop Endpoint Command with Suspend (SP) flag set.
Place individual ports into suspend mode by writing '3' for Port Link State
(PLS) field into PORTSC register. This can only be done when the port is in
Enabled state. When writing, the Port Link State Write Strobe (LWS) bit shall
be set to '1'.
Allocate an xhci_command and stash it in xhci_virt_device to wait completion for
the last Stop Endpoint Command. Use the Suspend bit in TRB to indicate the Stop
Endpoint Command is for port suspend. Based on Sarah's suggestion.
Port Resume:
Write '0' in PLS field, device will transition to running state.
Ring an endpoints' doorbell to restart it.

When the system suspends and a host controller's power is lost, the USB
core attempts to revive any USB devices that had the persist_enabled flag
set. For non-SuperSpeed devices, it will disable the port, and then set
the udev->reset_resume flag. This will cause the USB core to reset the
device, verify the device descriptors to make sure it's the same device,
and re-install any non-default configurations or alternate interface
settings.
However, we can't disable SuperSpeed root hub ports because that turns off
SuperSpeed terminations, which will inhibit any devices connecting at USB
3.0 speeds. (Plus external hubs don't allow SuperSpeed ports to be
disabled.)
Because of this logic in hub_activate():
/* We can forget about a "removed" device when there's a
* physical disconnect or the connect status changes.
*/
if (!(portstatus & USB_PORT_STAT_CONNECTION) ||
(portchange & USB_PORT_STAT_C_CONNECTION))
clear_bit(port1, hub->removed_bits);
if (!udev || udev->state == USB_STATE_NOTATTACHED) {
/* Tell khubd to disconnect the device or
* check for a new connection
*/
if (udev || (portstatus & USB_PORT_STAT_CONNECTION))
set_bit(port1, hub->change_bits);
} else if (portstatus & USB_PORT_STAT_ENABLE) {
/* The power session apparently survived the resume.
* If there was an overcurrent or suspend change
* (i.e., remote wakeup request), have khubd
* take care of it.
*/
if (portchange)
set_bit(port1, hub->change_bits);
} else if (udev->persist_enabled) {
udev->reset_resume = 1;
set_bit(port1, hub->change_bits);
} else {
/* The power session is gone; tell khubd */
usb_set_device_state(udev, USB_STATE_NOTATTACHED);
set_bit(port1, hub->change_bits);
}
a SuperSpeed device after a resume with a loss of power will never get the
reset_resume flag set. Instead the core will assume the power session
survived and that the device still has the same address, configuration,
and alternate interface settings. The xHCI host controller will have no
knowledge of the device (since all xhci_virt_devices were destroyed when
power loss was discovered, and xhci_discover_or_reset_device() has not
been called), and all URBs to the device will fail.
If the device driver responds by resetting the device, everything will
continue smoothly. However, if lsusb is used before the device driver
resets the device (or there is no driver), then all lsusb descriptor
fetches will fail.
The quick fix is to pretend the port is disabled in hub_activate(), by
clearing the local variable. But I'm not sure what other parts of the hub
driver need to be changed because they have assumptions about when ports
will be disabled.

If xhci_discover_or_reset_device() is called to reset a device which does

This would prevent the reset device failure, possibly due to the xHC restore

This is based on an initial patch by Rahul Ruikar.
The goku_remove() function can be called before device_register() so it
can call device_unregister() improperly. Also if the call to
device_register() fails we need to call put_device().
As I was changing the error handling in goku_probe(), I noticed that
the label was "done" but actually if the function succeeds we return
earlier. I renamed the error path to "err" instead of "done."
