musb-new: port of Linux musb driver 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>

musb-new: am35x backend driver Backend driver for MUSB OTG controllers found on TI AM35x. It seems that on AM35X interrupt status registers can be updated _before_ core registers. As we don't use true interrupts in U-Boot and poll interrupt status registers instead this can result in interrupt handler being called with non-updated core registers. This confuses the code and result in hanged transfers. Add a small delay in am35x_interrupt as a workaround. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>

omap4: Drop redundant CONFIG_OMAP4430 symbol While there are a few different OMAP4 SoCs, today we always set CONFIG_OMAP4430 and CONFIG_OMAP44XX. Convert the few test of CONFIG_OMAP4430 to CONFIG_OMAP44XX. Cc: Marek Vasut <marex@denx.de> Cc: Paul Kocialkowski <contact@paulk.fr> Signed-off-by: Tom Rini <trini@konsulko.com>
