1830 | r) Freescale Display Interface Unit | ||
1831 | |||
1832 | The Freescale DIU is a LCD controller, with proper hardware, it can also | ||
1833 | drive DVI monitors. | ||
1834 | |||
1835 | Required properties: | ||
1836 | - compatible : should be "fsl-diu". | ||
1837 | - reg : should contain at least address and length of the DIU register | ||
1838 | set. | ||
1839 | - Interrupts : one DIU interrupt should be describe here. | ||
1840 | |||
1841 | Example (MPC8610HPCD) | ||
1842 | display@2c000 { | ||
1843 | compatible = "fsl,diu"; | ||

1851 | This is the memory-mapped registers for on board FPGA. | ||
1852 | |||
1853 | Required properities: | ||
1854 | - compatible : should be "fsl,fpga-pixis". | ||
1855 | - reg : should contain the address and the lenght of the FPPGA register | ||

1868 | |||
1869 | MDC and MDIO lines connected to GPIO controllers are listed in the | ||
1870 | gpios property as described in section VIII.1 in the following order: | ||

1872 | MDC, MDIO. | ||
