| * USB: musb: be careful with 64K+ transfer lengths, host sideSergei Shtylyov2009-02-271-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Feeding 32-bit length cast down to 'u16' to min() to calculate the FIFO count in musb_host_tx() risks sending a short packet prematurely for transfer sizes over 64 KB. Similarly, although data transfer size shouldn't exceed 65535 bytes for the control endpoint, making musb_h_ep0_continue() more robust WRT URBs with possibly oversized buffer will not hurt either...

| * USB: musb: fix data toggle saving with shared FIFOSergei Shtylyov2009-02-271-6/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | For some strange reason the host side musb_giveback() decides that it's always got an IN transfer when the hardware endpoint is using a shared FIFO. This causes musb_save_toggle() to read the toggle state from the RXCSR register instead of TXCSR, and may also cause unneeded reloading of RX endpoint registers.

| * USB: musb: host endpoint_disable() oops fixesSergei Shtylyov2009-02-271-10/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The musb_h_disable() routine can oops in some cases: - It's not safe to read hep->hcpriv outside musb->lock, since it gets changed on completion IRQ paths. - The list iterators aren't safe to use in that way; just remove the first element while !list_empty(), so deletions on other code paths can't make trouble. We need two "scrub the list" loops because only one branch should touch hardware and advance the schedule.

| * USB: musb: fix urb_dequeue() methodSergei Shtylyov2009-02-271-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The urb_dequeue() method forgets to unlink 'struct musb_qh' from the control or bulk schedules when the URB being cancelled is the only one queued to its endpoint. That will cause musb_advance_schedule() to block once it reaches 'struct musb_qh' with now empty URB list, so URBs queued for other endpoints after the one being dequeued will not be served. Fix by unlinking the QH from the list except when it's already being handled (typically by musb_giveback). Since a QH with an empty URB list is now supposed to be freed, do that. And remove a now-useless check from musb_advance_schedule().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The input queue should be used for TX on endpoints which share FIFO hardware. The host TX path wasn't doing that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the musb build fixes for DaVinci got merged (RC3?), kick in the other bits needed to get it finally *working* in mainline: - Use clk_enable()/clk_disable() ... the "always enable USB clocks" code this originally relied on has since been removed. - Initialize the USB device only after the relevant I2C GPIOs are available, so the host side can properly enable VBUS. - Tweak init sequencing to cope with mainline's relatively late init of the I2C system bus for power switches, transceivers, and so on. Sanity tested on DM6664 EVM for host and peripheral modes; that system won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also verified on OMAP3.

| * USB: usb_get_string should check the descriptor typeAlan Stern2009-02-271-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1218) fixes a problem with a radio-control joystick used in the "walkera 4#3" helicopter. This device responds to the initial Get-String-Descriptor request for string 0 (which is really the list of supported languages) by sending its config descriptor! The usb_get_string() routine needs to check whether it got the right type of descriptor. Oddly enough, this sort of check is already present in usb_get_descriptor(). The patch changes the error code from -EPROTO to -ENODATA, because -EPROTO shows up in so many other contexts to indicate a hardware failure rather than a firmware error.

| * USB: EHCI: slow down ITD reuseKarsten Wiese2009-02-274-8/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ITDs are immediately recycled whenever their URB completes. However, EHCI hardware can sometimes remember some ITD state. This means that when the ITD is reused before end-of-frame it may sometimes cause the hardware to reference bogus state. This patch defers reusing such ITDs by moving them into a new ehci member cached_itd_list. ITDs resting in cached_itd_list are moved back into their stream's free_list once scan_periodic() detects that the active frame has elapsed. This makes the snd_usb_us122l driver (in kernel since .28) work right when it's hooked up through EHCI.

| * USB: fsl_qe_udc: Fix recursive locking bug in ch9getstatus()Anton Vorontsov2009-02-091-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The call chain is this: qe_udc_irq() <- grabs the udc->lock spinlock rx_irq() qe_ep0_rx() ep0_setup_handle() setup_received_handle() ch9getstatus() qe_ep_queue() <- tries to grab the udc->lock again It seems unsafe to temporarily drop the lock in the ch9getstatus(), so to fix that bug the lock-less __qe_ep_queue() function implemented and used by the ch9getstatus().

| * USB: fsl_qe_udc: Fix oops on QE UDC probe failureAnton Vorontsov2009-02-091-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of probing errors the driver kfrees the udc_controller, but it doesn't set the pointer to NULL. When usb_gadget_register_driver is called, it checks for udc_controller != NULL, the check passes and the driver accesses nonexistent memory. Fix this by setting udc_controller to NULL in case of errors. While at it, also implement irq_of_parse_and_map()'s failure and cleanup cases.

| * USB: Driver for Freescale QUICC Engine USB Host ControllerAnton Vorontsov2009-01-2811-0/+3862
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the FHCI USB controller, as found in the Freescale MPC836x and MPC832x processors. It can support Full or Low speed modes. Quite a lot the hardware is doing by itself (SOF generation, CRC generation and checking), though scheduling and retransmission is on software's shoulders. This controller does not integrate the root hub, so this driver also fakes one-port hub. External hub is required to support more than one device.
