| * usb: musb: ux500_dma: fix sparse warningFelipe Balbi2013-03-27
| | | | | | | | | | | | | | | | fix the following sparse warning: drivers/usb/musb/ux500_dma.c:60:6: warning: symbol 'ux500_dma_callback' was not declared. Should it be static? Signed-off-by: Felipe Balbi <balbi@ti.com>

| * usb: musb: gadget: clear gadget_driver when gadget is stoppedGrazvydas Ignotas2013-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some musb glue drivers use gadget_driver pointer to know if any gadget drivers are loaded at some moment and base further decisions on it, like to do runtime suspend/resume or not. Right now the pointer is left alone on stop and OMAP musb glue later does wrong runtime_pm decisions because of it. Clear the gadget_driver pointer on remove, it's invalid after stop anyway.

| * usb: musb: core: honour initial transceiver stateGrazvydas Ignotas2013-03-22
| | | | | | | | | | | | | | | | | | | | As the usb transceiver driver usually starts first, it should already have default_a variable set according to ID pin state, so don't override it. In case default_a was not changed by trasceiver, it will default to 0 and this code will work as before.

| * usb: phy: ab8500-usb: update irq handling codeFabio Baltieri2013-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Update irq handling code to notify all possible link status changes of AB8500 and AB8505 to the ux500-musb glue driver. The additional event codes will be used for pm-runtime implementation, and are defined in a separate ux500-specific header. This also modify the irq registration code to use devm_* helpers and drop all non necessary fail path code.

| * usb: musb: gadget: do *unmap_dma_buffer* only for valid DMA addrKishon Vijay Abraham I2013-03-18
| | | | | | | | | | | | | | | | | | | | | | | | musb does not use DMA buffer for ep0 but it uses the same giveback function *musb_g_giveback* for all endpoints (*musb_g_ep0_giveback* calls *musb_g_giveback*). So for ep0 case request.dma will be '0' and will result in kernel OOPS if tried to *unmap_dma_buffer* for requests in ep0. Fixed it by doing *unmap_dma_buffer* only for valid DMA addr and checking that musb_ep->dma is valid when unmapping.

| | | | | | | | | | | | | | | | | | Commit 80ab72e1 (usb: musb: omap2430: fix the readiness check in omap_musb_mailbox) made the check incorrect, as we will lose the glue/link status during the normal built-in probe order (twl4030_usb is probed after musb omap2430, but before musb core is ready). As a result, if you boot with USB cable on and load g_ether, the connection does not work as the code thinks the cable is off and the phy gets powered down immediately. This is a major regression in 3.9-rc1. So the proper check should be: exit if _glue is NULL, but if it's initialized we memorize the status, and then check if the musb core is ready.

| | * | | usb: musb: Double buffering issues in host mode TXsupriya karanth2013-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever an URB is programmed for transfer, the TXFIFO is flushed. This results in valid packets of the previous transfer to get flushed when double buffering is enabled (The MUSB_TXCSR_FIFONOTEMPTY bit in TXCSR is set indicating that a packet in the FIFO is yet to be sent) For ex:- In Host mode Audio, noise is heard in the headset when double buffering is enabled on the ISO endpoint. The fifo flush is removed for double buffering case. The fifo is now flushed only in cases of error or when aborting a transfer. Also, In Host MSC case, data toggle errors are seen when double buffering is enabled on the bulk endpoint. Whenever an URB is programmed for transfer, the data toggle is set manually resulting in data toggle errors on the bus. Leave the data toggle handling upto the hardware in the double buffering case.
