1* Parallel I/O Ports
2
3This node configures Parallel I/O ports for CPUs with QE support.
4The node should reside in the "soc" node of the tree.  For each
5device that using parallel I/O ports, a child node should be created.
6See the definition of the Pin configuration nodes below for more
7information.

9Required properties:
10- device_type : should be "par_io".
11- reg : offset to the register set and its length.
12- num-ports : number of Parallel I/O ports
13
14Example:
15par_io@1400 {
16	reg = <1400 100>;
17	#address-cells = <1>;
18	#size-cells = <0>;
19	device_type = "par_io";
20	num-ports = <7>;
21	ucc_pin@01 {
22		......
23	};
24
25Note that "par_io" nodes are obsolete, and should not be used for
26the new device trees. Instead, each Par I/O bank should be represented
27via its own gpio-controller node:
28
29Required properties:
30- #gpio-cells : should be "2".
31- compatible : should be "fsl,<chip>-qe-pario-bank",
32  "fsl,mpc8323-qe-pario-bank".
33- reg : offset to the register set and its length.
34- gpio-controller : node to identify gpio controllers.
35
36Example:
37	qe_pio_a: gpio-controller@1400 {
38		#gpio-cells = <2>;
39		compatible = "fsl,mpc8360-qe-pario-bank",
40		"fsl,mpc8323-qe-pario-bank";
41		reg = <0x1400 0x18>;
42		gpio-controller;
43	  };
44
45	qe_pio_e: gpio-controller@1460 {
46		#gpio-cells = <2>;
47		compatible = "fsl,mpc8360-qe-pario-bank",
48			     "fsl,mpc8323-qe-pario-bank";
49		reg = <0x1460 0x18>;
50		gpio-controller;
51	  };
