* | usb: gadget: ether set wMaxPacketSizeTroy Kisky2013-10-20-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set wMaxPacketSize for full speed descriptors fs_source_desc, fs_sink_desc to 64. Full-speed bulk endpoint can have a maximum packet size of 8, 16, 32, or 64 bytes, so choice 64. The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize set to 512. That is the only legal value for high speed bulk endpoints. Strictly speaking, this patch is not needed because usb_ep_autoconfig will call ep_matches which will override wMaxPacketSize for BULK endpoints only with the size associated with the endpoint setup by the udc driver. But if you want to rely on this, you may as well combine the full speed descriptor with the high speed descriptor to minimize confusion. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

* | exynos: usb: Switch USB VBUS GPIOs to be device tree configuredJulius Werner2013-10-20-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Exynos boards, such as the SMDK5250, control USB port power through a GPIO pin. For now this had been hardcoded in the exynos5-dt board file, but not all boards use the same pin, requiring local changes to support different boards. This patch moves the GPIO initialization into the USB host controller drivers which they belong to, and uses the samsung,vbus-gpio parameter in the device tree to configure it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wait_until_[rx|tx]ep_ready functions return a u8 to indicate success containing the value 0, 1 or -1.

* | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Move the struct ehci_ctrl defition from ehci-hcd.c into ehci.h so it can be re-used by drivers. In particular, the mv_udc driver can benefit from this move.

* | usb: mv_udc: Clean up the EP initializationMarek Vasut2013-07-29-12/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the constant values that are programmed into mv_ep.ep into separate static const structure so they can be memcpy()'d when the initialization happens. Moveover, we only every init NUM_ENDPOINTS, not 2 * NUM_ENDPOINTS, so fix this bug as well.

* | usb: mv_udc: Move endpoint array into driver dataMarek Vasut2013-07-29-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | The endpoints are operated on a per-controller basis, move the endpoint array into controller's private data. Also shuffle the struct mv_ep structure definition just above the definition of the struct mv_drv so they're well grouped together.
