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: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/media/video-interfaces.txt 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>; }; }; Tomi
Thank you! I will update patches according to this layout later. -- Thanks, -Zhou -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
