      [ARM] 3096/1: Add SharpSL Zaurus power and battery management core driver · 078abcf9

      Patch from Richard Purdie
      
      This patch adds a power and battery management core driver which with
      the addition of the right device files, supports the c7x0 and cxx00
      series of Sharp Zaurus handhelds.
      
      The driver is complex for several reasons. Battery charging is manually
      monitored and controlled. When suspended, the device needs to
      periodically partially resume, check the charging status and then
      re-suspend. It does without bothering the higher linux layers as
      a full resume and re-suspend is unnecessary. The code is carefully
      written to avoid interrupts or calling code outside the module under
      these circumstances. It also vets the various wake up sources and
      monitors the device's power situation.
      
      Hooks to limit the backlight intensity and to notify the battery
      monitoring code of backlight events are connected/added as the
      backlight is one of the biggest users of power on the device.
