I believe we have settled on a final representation, it just hasn't been added into linux-next yet. See: http://gitorious.org/linux-pwm/linux-pwm/commit/d3ce73e5dc86646a6302f2b0f7dd40e8c552fa04 > I am not sure if it is better to have the lcd within the display > controller as with i2c/spi, or a separate node.

Equally, there's been extensive discussion re: how to represent the NVIDIA display controller in DT. I strongly believe that U-Boot shouldn't go ahead in isolation with a binding that's completely unrelated to what's happening in the kernel. Please can you take what Thierry is working on for the kernel, and/or contribute to that binding etc., so we don't end up with multiple ways of doing the same thing. Part of the whole point of DT is to have a single way of representing HW that multiple OSs (or perhaps bootloaders) cna use. If everyone just goes and does their own thing, we've lost. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
