+ r) Freescale Display Interface Unit
+
+ The Freescale DIU is a LCD controller, with proper hardware, it can also
+ drive DVI monitors.
+
+ Required properties:
+ - compatible : should be "fsl-diu".
+ - reg : should contain at least address and length of the DIU register
+ set.
+ - Interrupts : one DIU interrupt should be describe here.
+
+ Example (MPC8610HPCD)
+ display@2c000 {
+ compatible = "fsl,diu";
+ reg = <0x2c000 100>;
+ interrupts = <72 2>;
+ interrupt-parent = <&mpic>;
+ };
+
+ s) Freescale on board FPGA
+
+ This is the memory-mapped registers for on board FPGA.
+
+ Required properities:
+ - compatible : should be "fsl,fpga-pixis".
+ - reg : should contain the address and the lenght of the FPPGA register
+ set.
+
+ Example (MPC8610HPCD)
+ board-control@e8000000 {
+ compatible = "fsl,fpga-pixis";
+ reg = <0xe8000000 32>;
+ };
+
+ r) MDIO on GPIOs
+
+ Currently defined compatibles:
+ - virtual,gpio-mdio
+
+ MDC and MDIO lines connected to GPIO controllers are listed in the
+ gpios property as described in section VIII.1 in the following order:
+
+ MDC, MDIO.
+
+ Example:
+
+ mdio {
+ compatible = "virtual,mdio-gpio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ gpios = <&qe_pio_a 11
+ &qe_pio_c 6>;
