* | usb: chipidea-imx: Fix usb initializationAlexander Shiyan2013-03-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | This patch fix chipidea-imx usb initialization. "imx_chipidea_port_init" was moved before PORTSC setup in the commit "USB i.MX chipidea: implement post init support". This change breaks usb function with ULPI. Patch moves port initialization back after PORTSC setup, so it works again. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * USB i.MX: Add chipidea gadget supportSascha Hauer2013-02-152-7/+15
| | | | | | | | | | | | | | | | This adds USB gadget support to the i.MX chipidea driver. Basically we have to add a register function to the fsl udc driver and call this from the chipidea driver if device mode is selected. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * USB i.MX6: Add HSIC supportSascha Hauer2013-02-141-0/+60
| | | | | | | | | | | | | | | | | | | | HSIC needs some special setup for i.MX6. Most ugly detail is that the HSIC needs help of the IOMUX to configure a pullup on the strobe line. This has to be done after the ehci controller has started. Fortunately there is only one muxing possibility for the HSIC ports on i.MX6, so we can simply control the iomux from the usbmisc driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For proper USB function the usbmisc registers have to be initialized. This patch adds a driver which matches for the usbmisc registers. This driver is called from a new driver which binds to the USB ports to configure the misc registers. After that the driver registers the EHCI driver and an ULPI transceiver if necessary. Currently only host mode is supported, but device support can be added later.

* usb: add flow control to u_serialRobert Jarzmik2012-10-291-8/+17
| | | | | | | | | | | | | | | | | | | When using the serial console over USB to download files, and when the USB bandwidth is pushed to its limits, the barebox UDC device won't be able to absorb all the traffic. Modify the u_serial gadget so that if there is not enough room in buffers, don't push USB requests down the gadget driver, so that it is saturated, and give it a chance to NAK requests. The previous behaviour was loosing bytes (as kfifo_put is lossy). The fixed behavious is lossless (based on USB NAK protocol). While at it, increase a bit buffer sizes to 8kB to absorb heavy transfers such as a linux kernel image.
