    [PATCH] USB: omap_udc updates · 14f651a8
    David Brownell authored
    This is a collection of updates to the OMAP UDC driver.
    
      - OMAP-1510 support, including DMA (the DMA controller isn't quite
        the same as on newer chips) but not double buffering.
    
      - Some PIO work:
    
          * fix some races that showed up on OMAP-1510
    
          * tracking down annoying PIO-OUT lossage and making double buffering
            start to behave (needed as fallback if all DMA channels are in use).
    
      - DMA-IN works on both 1510 and 16xx
    
    Plus minor cleanups.
