powerpc/83xx: Add power management support for MPC8315E-RDB boards
Anton Vorontsov [Thu, 10 Dec 2009 18:01:03 +0000 (21:01 +0300)]
- Add nodes for PMC and GTM controllers. GTM4 can be used as a wakeup
  source;

- Add fsl,magic-packet properties to eTSEC nodes, i.e. wake-on-lan
  support. Unlike MPC8313 processors, MPC8315 can resume from deep
  sleep upon magic packet reception.
