      [POWERPC] Add of_device_is_available function · 834d97d4
      Josh Boyer 提交于
      IEEE 1275 defined a standard "status" property to indicate the operational
      status of a device.  The property has four possible values: okay, disabled,
      fail, fail-xxx.  The absence of this property means the operational status
      of the device is unknown or okay.
      
      This adds a function called of_device_is_available that checks the state
      of the status property of a device.  If the property is absent or set to
      either "okay" or "ok", it returns 1.  Otherwise it returns 0.

      [POWERPC] Add of_get_next_parent() · f4eb0107
      Michael Ellerman 提交于
      Iterating through a device node's parents is simple enough, but dealing
      with the refcounts properly is a little ugly, and replicating that logic
      is asking for someone to get it wrong or forget it all together, eg:
      
      while (dn != NULL) {
      	/* loop body */
      	tmp = of_get_parent(dn);
      	of_node_put(dn);
      	dn = tmp;
      }
      
      So add of_get_next_parent(), inspired by of_get_next_child().  The
      contract is that it returns the parent and drops the reference on the
      current node, this makes the loop look like:
      
      while (dn != NULL) {
      	/* loop body */
      	dn = of_get_next_parent(dn);
      }
