Hi Andy, Is this a patch from the Android kernel tree? Is there anybody testing the upstream kernel on this hardware? Past efforts to support old hardware that nobody tests upstream have resulted in all pain and no gain, and I'm not eager to repeat that experience. thanks, -Len On Mon, Jun 6, 2016 at 1:06 PM, Andy Shevchenko [off-list ref] wrote:

Add CPU ID for Atom Z34xx processors. Datasheets indicate support for this, detailed information about potential quirks or limitations are missing, though. So we just reuse the definition for the previous ATOM series. The quite similar values (C1 is slightly deviated) are used in the official Intel Edison BSP.
