(e.g. the phy registers in the control module are nearly identical, differing only in some bits related to GPIO-mode) On 9 March 2015 at 22:41, Tony Lindgren wrote: > Note that we still are missing basic support for dm814x in mainline, > I'm planning to tackle that at some point but I don't know when I'm > going to get to it.. Do ping me if you have questions. While I still don't have time to really throw myself on the task myself, and I'm still hindered by insufficient knowledge of the kernel, I do have quite a bit of experience with the processor itself. BTW, w.r.t. the old "official" TI kernel for dm81xx: there are actually two relevant forks of the unmaintained arago-omap3/ti81xx-master branch, namely: http://arago-project.org/git/projects/?p=linux-ipnc-rdk-dm81xx.git http://arago-project.org/git/projects/?p=linux-dvr-rdk-dm81xx.git which contain various bugfixes, including for usb (though also patches specific to those SDKs).
