-  a) MDIO IO device
-
-  The MDIO is a bus to which the PHY devices are connected.  For each
-  device that exists on this bus, a child node should be created.  See
-  the definition of the PHY node below for an example of how to define
-  a PHY.
-
-  Required properties:
-    - reg : Offset and length of the register set for the device
-    - compatible : Should define the compatible device type for the
-      mdio.  Currently, this is most likely to be "fsl,gianfar-mdio"
-
-  Example:
-
-        mdio@24520 {

-      services interrupts for this device.
-    - phy-handle : The phandle for the PHY connected to this ethernet
-      controller.

-   This node configures Parallel I/O ports for CPUs with QE support.
-   The node should reside in the "soc" node of the tree.  For each
-   device that using parallel I/O ports, a child node should be created.
-   See the definition of the Pin configuration nodes below for more
-   information.
-
-   Required properties:
-   - device_type : should be "par_io".
-   - reg : offset to the register set and its length.
-   - num-ports : number of Parallel I/O ports
-
-   Example:
-        par_io@1400 {
-                reg = <1400 100>;
-                #address-cells = <1>;
-                #size-cells = <0>;
-                device_type = "par_io";
-                num-ports = <7>;

-   vi) Pin configuration nodes
-
-   Required properties:
-   - linux,phandle : phandle of this node; likely referenced by a QE
-     device.
-   - pio-map : array of pin configurations.  Each pin is defined by 6
-     integers.  The six numbers are respectively: port, pin, dir,
-     open_drain, assignment, has_irq.
-     - port : port number of the pin; 0-6 represent port A-G in UM.
-     - pin : pin number in the port.
-     - dir : direction of the pin, should encode as follows:
-
-        0 = The pin is disabled
-        1 = The pin is an output
-        2 = The pin is an input
-        3 = The pin is I/O
-
-     - open_drain : indicates the pin is normal or wired-OR:
-
-        0 = The pin is actively driven as an output
-        1 = The pin is an open-drain driver. As an output, the pin is
-            driven active-low, otherwise it is three-stated.
-
-     - assignment : function number of the pin according to the Pin Assignment
-       tables in User Manual.  Each pin can have up to 4 possible functions in
-       QE and two options for CPM.
-     - has_irq : indicates if the pin is used as source of external
-       interrupts.
-

-
-   vii) Multi-User RAM (MURAM)
-
-   Required properties:
-   - compatible : should be "fsl,qe-muram", "fsl,cpm-muram".
-   - mode : the could be "host" or "slave".
-   - ranges : Should be defined as specified in 1) to describe the
-      translation of MURAM addresses.

-      bus that can be allocated as data/parameter

-
-   viii) Uploaded QE firmware
-
-         If a new firwmare has been uploaded to the QE (usually by the
-         boot loader), then a 'firmware' child node should be added to the QE
-         node.  This node provides information on the uploaded firmware that
-         device drivers may need.
-
-         Required properties:
-         - id: The string name of the firmware.  This is taken from the 'id'
-               member of the qe_firmware structure of the uploaded firmware.
-               Device drivers can search this string to determine if the
-               firmware they want is already present.
-         - extended-modes: The Extended Modes bitfield, taken from the
-                           firmware binary.  It is a 64-bit number represented
-                           as an array of two 32-bit numbers.
-         - virtual-traps: The virtual traps, taken from the firmware binary.
-                          It is an array of 8 32-bit numbers.
-
-         Example:
-
-                firmware {
-                        id = "Soft-UART";
-                        extended-modes = <0 0>;
-                        virtual-traps = <0 0 0 0 0 0 0 0>;

-   k) Global Utilities Block
-
-   The global utilities block controls power management, I/O device
-   enabling, power-on-reset configuration monitoring, general-purpose
-   I/O signal configuration, alternate function selection for multiplexed
-   signals, and clock control.
-
-   Required properties:
-
-    - compatible : Should define the compatible device type for
-      global-utilities.
-    - reg : Offset and length of the register set for the device.
-
-  Recommended properties:
-
-    - fsl,has-rstcr : Indicates that the global utilities register set
-      contains a functioning "reset control register" (i.e. the board
-      is wired to reset upon setting the HRESET_REQ bit in this register).
-
-    Example:
-
-        global-utilities@e0000 {        /* global utilities block */
-                compatible = "fsl,mpc8548-guts";
-                reg = <e0000 1000>;
-                fsl,has-rstcr;
-        };

-   l) Freescale Communications Processor Module
-
-   NOTE: This is an interim binding, and will likely change slightly,
-   as more devices are supported.  The QE bindings especially are
-   incomplete.
-
-   i) Root CPM node
-
-   Properties:
-   - compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe".
-   - reg : A 48-byte region beginning with CPCR.
-
-   Example:
-        cpm@119c0 {
-                #address-cells = <1>;
-                #size-cells = <1>;
-                #interrupt-cells = <2>;
-                compatible = "fsl,mpc8272-cpm", "fsl,cpm2";

-        }
-
-   ii) Properties common to mulitple CPM/QE devices
-
-   - fsl,cpm-command : This value is ORed with the opcode and command flag
-                       to specify the device on which a CPM command operates.
-
-   - fsl,cpm-brg : Indicates which baud rate generator the device
-                   is associated with.  If absent, an unused BRG
-                   should be dynamically allocated.  If zero, the
-                   device uses an external clock rather than a BRG.
-
-   - reg : Unless otherwise specified, the first resource represents the
-           scc/fcc/ucc registers, and the second represents the device's
-           parameter RAM region (if it has one).

-   viii) Multi-User RAM (MURAM)
-
-   The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
-
-   Ranges must be set up subject to the following restrictions:
-
-   - Children's reg nodes must be offsets from the start of all muram, even
-     if the user-data area does not begin at zero.
-   - If multiple range entries are used, the difference between the parent
-     address and the child address must be the same in all, so that a single
-     mapping can cover them all while maintaining the ability to determine
-     CPM-side offsets with pointer subtraction.  It is recommended that
-     multiple range entries not be used.
-   - A child address of zero must be translatable, even if no reg resources
-     contain it.
-
-   A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
-   indicate the portion of muram that is usable by the OS for arbitrary
-   purposes.  The data node may have an arbitrary number of reg resources,
-   all of which contribute to the allocatable muram pool.
-
-   Example, based on mpc8272:
-
-        muram@0 {
-                #address-cells = <1>;
-                #size-cells = <1>;
-                ranges = <0 0 10000>;
-
-                data@0 {
-                        compatible = "fsl,cpm-muram-data";
-                        reg = <0 2000 9800 800>;
-                };
-        };
-
-   m) Chipselect/Local Bus
-
-   Properties:
-   - name : Should be localbus
-   - #address-cells : Should be either two or three.  The first cell is the
-                      chipselect number, and the remaining cells are the
-                      offset into the chipselect.
-   - #size-cells : Either one or two, depending on how large each chipselect
-                   can be.
-   - ranges : Each range corresponds to a single chipselect, and cover
-              the entire access window as configured.
-
-   Example:
-        localbus@f0010100 {
-                compatible = "fsl,mpc8272-localbus",
-                             "fsl,pq2-localbus";
-                #address-cells = <2>;
-                #size-cells = <1>;
-                reg = <f0010100 40>;
-
-                ranges = <0 0 fe000000 02000000
-                          1 0 f4500000 00008000>;

-                        bank-width = <4>;
-                        device-width = <1>;
-                };

-                        reg = <1 0 20>;
-                        compatible = "fsl,mpc8272ads-bcsr";
