1832 r) Freescale Display Interface Unit
1833
1834 The Freescale DIU is a LCD controller, with proper hardware, it can also
1835 drive DVI monitors.
1836
1837 Required properties:
1838 - compatible : should be "fsl-diu".
1839 - reg : should contain at least address and length of the DIU register
1840 set.
1841 - Interrupts : one DIU interrupt should be describe here.
1842
1843 Example (MPC8610HPCD)
1844 display@2c000 {
1845 compatible = "fsl,diu";
1846 reg = <0x2c000 100>;
1847 interrupts = <72 2>;
1848 interrupt-parent = <&mpic>;

1851 s) Freescale on board FPGA
1852
1853 This is the memory-mapped registers for on board FPGA.
1854
1855 Required properities:
1856 - compatible : should be "fsl,fpga-pixis".
1857 - reg : should contain the address and the lenght of the FPPGA register
1858 set.
1859
1860 Example (MPC8610HPCD)
1861 board-control@e8000000 {
1862 compatible = "fsl,fpga-pixis";
1863 reg = <0xe8000000 32>;
1864 };
1865
1866 r) MDIO on GPIOs
1867
1868 Currently defined compatibles:
1869 - virtual,gpio-mdio
1870
1871 MDC and MDIO lines connected to GPIO controllers are listed in the
1872 gpios property as described in section VIII.1 in the following order:
1873
1874 MDC, MDIO.
1875
1876 Example:
1877
1878 mdio {
1879 compatible = "virtual,mdio-gpio";
1880 #address-cells = <1>;
1881 #size-cells = <0>;
1882 gpios = <&qe_pio_a 11
1883 &qe_pio_c 6>;
