But, this way we end up describing MDSS hardware block twice: once with the proper device structure and once more in the simple-framebuffer definition. I think this is a bit strange. I understand your point of having a device-specific compatible string and also having a verifiable schema, but I think it's an overkill here. Consider regulator supplies of this simple-framebuffer. Obviously some of them supply the panel and not the SoC parts. Should we also include the panel into the respective compat string? What about describing the device with two different DSI panels? I think this explodes too quickly to be useful. I'd cast my (small) vote into continuing using the simple-framebuffer as is, without additional compatible strings and extend the bindings allowing unbound number of interconnects. -- With best wishes Dmitry
