* musb: Disable extra printsLokesh Vutla2013-08-151-12/+8
| | | | | | | | | | There are many musb prints in SPL and U-Boot log. These prints are required only during musb debug. So replacing printk with pr_debug in musb_core. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Tested-by: Heiko Schocher <hs@denx.de> Acked-by: Heiko Schocher <hs@denx.de>
* musb: set MUSB speed based on CONFIGBin Liu2013-04-081-0/+2
| | | | | | | | Do not config MUSB to highspeed mode if CONFIG_USB_GADGET_DUALSPEED is not set, in which case Ether gadget only operates in fullspeed. Reviewed-by: Tom Rini <trini@ti.com> Signed-off-by: Bin Liu <b-liu@ti.com>
* musb: am335x: disable bulk split-combine featureBin Liu2013-04-081-0/+5
| | | | | | | | | | | | | | | | | | | On TI AM335x devices, MUSB has bulk split/combine feature enabled in the ConfigData register, but the current MUSB driver does not support it yet. Therefore, disable the feature for now, until the driver adds the support. One usecase which is broken because of this feature is that Ether gadget stops working in Fullspeed mode (by un-defining CONFIG_USB_GADGET_DUALSPEED) After desabled this feature, MUSB driver send packets in proper size (no more than 64 bytes) in Fullspeed mode. This has been validated with Ether gadget in Fullspeed mode on AM335x EVM. Signed-off-by: Bin Liu <b-liu@ti.com>
* musb-new: port of Linux musb driverIlya Yanok2012-11-201-0/+2497
Existing U-Boot musb driver has no support for the new gadget framework and also seems to have other limitations. As gadget framework is ported from Linux it seems pretty natural to port musb gadget driver as well. This driver supports both host and peripheral modes. This is not a replacement for current musb driver (at least now) as there are still some consumers of the old UDC interface. No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be defined. Virtual root hub device is not implemented. Known problems: with no devices connected usb_lowlevel_start() fails. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>
