| 2 | |
| 3 | The SM SM501 is a LCD controller, with proper hardware, it can also |
| 4 | drive DVI monitors. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible : should be "smi,sm501". |
| 8 | - reg : contain two entries: |
| 9 | - First entry: System Configuration register |
| 10 | - Second entry: IO space (Display Controller register) |
| 11 | - interrupts : SMI interrupt to the cpu should be described here. |
| 12 | - interrupt-parent : the phandle for the interrupt controller that |
| 13 | services interrupts for this device. |
| 14 | |
| 15 | Optional properties: |
| 16 | - mode : select a video mode: |
| 17 | <xres>x<yres>[-<bpp>][@<refresh>] |
| 18 | - edid : verbatim EDID data block describing attached display. |
| 19 | Data from the detailed timing descriptor will be used to |
| 20 | program the display controller. |

| 26 | Example for MPC5200: |
| 27 | display@1,0 { |
| 28 | compatible = "smi,sm501"; |
| 29 | reg = <1 0x00000000 0x00800000 |
| 30 | 1 0x03e00000 0x00200000>; |
| 31 | interrupts = <1 1 3>; |
| 32 | mode = "640x480-32@60"; |
| 33 | edid = [edid-data]; |
| 34 | }; |
