MUSB should now work out of the box on AM335x-based boards (beagle bone white and black) with DMA thanks to Sebastian's work. We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/ by selecting CONFIG_USB_GADGET_VERBOSE. s3c-hsotg got quite a few non-critical fixes but also learned a few new tricks (isochronous transfers, multi count support). The Marvel USB3 Controller driver got a memory leak fix. devm_usb_get_phy() learned not to return NULL, ever. Other than these patches, we have the usual set of cleanups ranging from removal of unnecessary *_set_drvdata() to using SIMPLE_DEV_PM_OPS. Signed-of-by: Felipe Balbi <balbi@ti.com>

| * usb: musb: cppi41: allow to defer probing if DMA isn't yet availableSebastian Andrzej Siewior2013-10-172-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If everything (musb, cppi41, phy) is built-in then musb will start without the dma engine printing only |musb-hdrc musb-hdrc.0.auto: Falied to request rx1. The reason for this is that the musb device structs are created & probed before those of the cppi41 device. So the cppi41 device is probed too late. As a workaround for this allow the musb_cppi41 part to defer the probe if everything is fine except for the missing DMA controller. In case of another error we continue.

| | | | | | | | | | | | | | | | | | | | | | In commit f3ce4d5 ("usb: musb: core: call dma_controller_destroy() in the err path") I erroneously assumed that the dma controller is not removed in the error patch. This was wrong because it happens later via musb_free(). That means the original commit can be reverted because it is wrong or we do this, so it is more obvious.

| * usb: musb: dsps: run the timer only on OTG systemsSebastian Andrzej Siewior2013-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I introduced this check here because it looked wrong in HOST only configurions. The timer would remove that session bit and will never come back and so there would not be another session. Now that I played with OTG for a while I belive this workaround is only required for the OTG mode because we have to end the session and then we have to try to start manually. Therefore, this patch limits this timer to the OTG only port mode so we don't need to poll around in device only mode.

| * usb: musb: dsps: redo the otg timerSebastian Andrzej Siewior2013-10-171-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the comments, we rely on the OTG timer because the core does not expose some important OTG details. So far this is all I know. After playing with OTG I stumbled over a problem: musb is recognized as a B-device without a problem. Whenever a cable is plugged, the VBUS rises, musb recognizes this as a starting session, sets the MUSB_DEVCTL_SESSION bit by itself and a RESET interrupt occurs, the session starts. Good. After a disconnect, the timer is started and re-starts itself because it remains in B_IDLE with the BDEVICE set. I didn't figure the the reason or the need for it. Nothing changes here except for OTG state from B to A device if the BDEVICE bit disappears. This doesn't make much sense to me because nothing happens after this. _IF_ we receive an interrupt before the state change then we may act on wrong condition. Plugging a B-device (and letting MUSB act as host) doesn't work here. The reason seems to be that the MUSB tries to start a session, it fails and then it removes the bit. So we never start as a host. This patch sets the MUSB_DEVCTL_SESSION bit in the IDLE state so musb can try to establish a session as host. After the bit is set, musb tries to start a session and if it fails it clears the bit. Therefore it will try over and over again until a session either as host or as device is established. The readout of the MUSB_DEVCTL register after the removal the MUSB_DEVCTL_SESSION (in A_WAIT_BCON) has been removed because it did not contain the BDEVICE bit set (in the second read) leading to A_IDLE. After plugging a host musb assumed that it is also a host and complained about a missing reset. However a third read of the register has has the BDEVICE bit set so it seems that it is not stable. This mostly what da8xx.c is doing except that we set the timer also after A_WAIT_BCON so the session bit can be triggered. Whit this change I was able to keep am335x-evm in OTG mode and plug in either a HOST or a DEVICE and in a random order and the device was recognized.

| * usb: musb: dsps: move try_idle to start hookSebastian Andrzej Siewior2013-10-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timer is initialized right after musb is probed. There is actually no need to have this timer running because _nothing_ will happen until we have the gadget loaded. Also we need this timer only if we run in OTG mode _and_ we need it also after the gadget has been replaced with another one. I've been looking at am35x.c, da8xx.c, omap2430.c, tusb6010.c. da8xx seem to have the same problem as dsps and doing mostly the same thing. tusb6010 seem to do something different and do some actual "idle / power saving" work so I am not too comfortable to remove musb_platform_try_idle() from musb_gadget_setup(). Therefore this patch does not start the timer if there is no gadget active (which is at musb_gadget_setup() at time). In order to have the timer active after the gadget is loaded it will be triggered from dsps_musb_enable().

| * usb: musb: call musb_start() only once in OTG modeSebastian Andrzej Siewior2013-10-171-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
