Re: [PATCH] N900: add device tree
Hi! This adds device tree with neccessary support to boot with functional video (on both emulator and real N900 device). Is this really correct? You have commented out the USB, so there is no way for a developer to interact with the device. Well... I do not have USB SDcard set up, so my testing was does it show failed to mount root message on screen. Now, if I do quick test of enabling it on 3.9, I get: DTC arch/arm/boot/dts/omap3-n900.dtb Error: arch/arm/boot/dts/omap3-n900.dts:92.2-3 label or path, 'usb_otg_hs', not found FATAL ERROR: Syntax error parsing input tree make[1]: *** [arch/arm/boot/dts/omap3-n900.dtb] Error 1 make: *** [dtbs] Error 2 . If you could test the patches with the USB support uncommented, that would be very good...

I can do that, but not before next week.
