      [PATCH] update adb driver · ce121b29
      Paul Mackerras authored
      This updates the ADB (Apple desktop bus) driver used on macs and
      powermacs.  The main change, from Ben Herrenschmidt, is that handlers
      are called without a lock held now.  It also adds a way for userland to
      obtain some information about individual ADB devices from the driver.

      [PATCH] Update ADB drivers in 2.5 · 121c2e79
      Paul Mackerras authored
      This updates the ADB driver and the three low-level ADB bus adaptor
      drivers used on powermacs.  The files affected are all in
      drivers/macintosh; they are adb.c, macio-adb.c, via-cuda.c and
      via-pmu.c.
      
      The main changes in this patch are:
      
      - Remove the use of global cli/sti and replace them with local cli/sti,
        spinlocks and semaphores as appropriate.
      - Use DECLARE_WORK/schedule_work instead of tq_struct/schedule_task.
      - Improvements to the PMU interrupt handling and sleep/wakeup code.
