| * SM SM501 |
| |
| The SM SM501 is a LCD controller, with proper hardware, it can also |
| drive DVI monitors. |
| |
| Required properties: |
| - compatible : should be "smi,sm501". |
| - reg : contain two entries: |
| - First entry: System Configuration register |
| - Second entry: IO space (Display Controller register) |
| - interrupts : SMI interrupt to the cpu should be described here. |
| - interrupt-parent : the phandle for the interrupt controller that |
| services interrupts for this device. |
| |
| Optional properties: |
| - mode : select a video mode: |
| <xres>x<yres>[-<bpp>][@<refresh>] |
| - edid : verbatim EDID data block describing attached display. |
| Data from the detailed timing descriptor will be used to |
| program the display controller. |
| - little-endian: availiable on big endian systems, to |
| set different foreign endian. |
| - big-endian: availiable on little endian systems, to |
| set different foreign endian. |
| |
| Example for MPC5200: |
| display@1,0 { |
| compatible = "smi,sm501"; |
| reg = <1 0x00000000 0x00800000 |
| 1 0x03e00000 0x00200000>; |
| interrupts = <1 1 3>; |
| mode = "640x480-32@60"; |
| edid = [edid-data]; |
| }; |
