Hi, Tomi,

I would recommend using the same style that is used in the OMAP DSS, imx
drm and exynos patches that are introducing DT support. They use ports
and endpoints as defined in:

with the addition of a simplified endpoint format, where the 'port' node
is not required.
To give an idea what it could look like, I've modified your example
above. It's just a rough example, you should study and think how it best
fits for mmp.
You could use the same format for the internal connections also, but I
didn't touch that. I think internal connections can as well be
configured separately, in a custom format, because there's no need for
external components to connect to the internal links.
mmp-disp@d420b000 {
compatible = "marvell,mmp-disp";
reg = <0xd420b000 0x1fc>;
interrupts = <0 41 0x4>;
internal-connections {
pipe1: pn-path {
input = "panel-graphic";
output = &disp_out;
}
}
disp_out: endpoint {
remote-endpoint = <&panel_in>;
marvell,rbswap;
marvell,spi;
};
status = "okay";
}
panel-xxx {
properties;
panel_in: endpoint {
remote-endpoint = <&disp_out>;
};
};

Thank you! I will update patches according to this layout later.
