      stmhal: Turn off DMA clocks when idle for 100 msec · b677f034
      Dave Hylands authored
      Turning on each DMA block increases the current consumption
      by about 8 mA. This code adds an idle timer for each DMA
      block and turns off the clocks when no streams are in use
      for 128 msec. Having a small timeout allows for improved
      performance when back-to-back transfers are being performed.
      
      The 128 msec is basically a guess.

      stmhal: Put IRQs into priority order. · 9f5486c7
      Dave Hylands authored
      - added some comments to explain the priority/sub-priority.
      - adds an entry for SDIO (to be used in a later patch)
      - increases DMA priority above USB so that DMA can be used
        for sdcard I/O when using USB Mass Storage.
