* usb: Prevent using reserved registers on DM36x usbAndrew Murray2013-10-10-5/+14
| | | | | | | | | | | | | | | | The musb driver defines and uses MUSB_CSR0_H_DIS_PING, however this bit is reserved on the DM36x. Thus this patch ensures that the reserved bit is not accesssed. It has been observed that some USB devices will fail to enumerate with errors such as 'error in inquiry' without this patch. See http://www.ti.com/litv/pdf/sprufh9a for details.

| * usb: Fix error handling in musb_hcd.cAndrew Murray2013-10-07-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wait_until_[rx|tx]ep_ready functions return a u8 to indicate success containing the value 0, 1 or -1. This patch changes the return type to an int to accommodate the negative return values. These functions are used in the file using calls such as if (!wait_until... Where a -1 is returned it is mishandled and treated as success instead of a CRC error. This patch addresses this.

* | usb: ehci: Fix test mode for connected portsJulius Werner2013-09-27-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EHCI controller has some very specific requirements for the USB 2.0 port test modes, which were not closely followed in the initial test mode commit. It demands that the host controller is completely shut down (all ports suspended, Run/Stop bit unset) when activating test mode, and will not work on an already enumerated port. This patch fixes that by introducing a new ehci_shutdown() function that closely follows the procedure listed in EHCI 4.14. Also, when we have such a function anyway, we might as well also use it in usb_lowlevel_stop() to make the normal host controller shutdown cleaner.
