[PATCH] USB: more omap_udc updates (dma and omap1710)
More omap_udc updates: * OMAP 1710 updates - new UDC bit for clearing endpoint toggle, affecting CLEAR_HALT - new OTG bits affecting wakeup * Fix the bug Vladimir noted, that IN-DMA transfer code path kicks in for under 1024 bytes (not "up to 1024 bytes") * Handle transceiver setup more intelligently - use transceiver whenever one's available; this can be handy for GPIO based, loopback, or transceiverless configs - cleanup correctly after the "unrecognized HMC" case * DMA performance tweaks - allow burst/pack for memory access - use 16 bit DMA access most of the time on TIPB * Add workarounds for some DMA errata (not observed "in the wild"): - DMA CSAC/CDAC reads returning zero - RX/TX DMA config registers bit 12 always reads as zero (TI patch) * More "sparse" warnings removed, notably "changing" the SETUP packet to return data in USB byteorder (an API change, null effect on OMAP except for these warnings).
