I have EMAC, EDMA, NAND, Audio, VGA, USB 1.1 and USB 2.0 working at the moment. You can see my patches at [1]. I've splitted all changes into branches for submitting different trees. What you can find in branches are: * hawk-board-code3: This branch is for Hawk related patches * soc-common: Changes needed in mach-davinci arch files for Hawkboard * da8xx-nand: NAND related changes, for linux-mtd * musb-da8xx2: For USB OTG, I will drop these when they are in mainline. * da8xx-fb: Framebuffer related changes, will go through fb tree. * asoc2: For audio, for alsa tree. These are based on rc2 still...
