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>;
};
