Bug#774067: linux 3.16.7-ckt: [patch] please add a dts for the LinkSprite pcDuino V3
Source: linux
Version: 3.16.7-ckt2-1
Severity: wishlist
Tags: patch
On the debian-arm mailinglist, a user has asked for support for
the "LinkSprite pcDuino V3" board (see the thread starting at
https://lists.debian.org/debian-arm/2014/12/msg00052.html).
Driver-wise all core components of the board (serial console,
MMC, SATA, USB, wired ethernet) are supported by kernel 3.16, it
just lacks an appropriate device-tree file, which was added
upstream in kernel 3.17. Attached is a patch to backport the
device-tree file. As this is a completely self-contained
addition and does not bring any code changes, I believe this to
be suitable for inclusion into Jessie despite the freeze.
Regards,
Karsten

+The current GPL only licensing on the DTSI makes it very impractical for other
+software components licensed under another license.
+
+In order to make it easier for them to reuse our device trees, relicense our
+device trees under a GPL/X11 dual-license.
