Bug#763897: linux 3.16.3-2: [PATCH] Please add a dts for the LeMaker Banana Pi

Source: linux 
Version: 3.16.3-2
Severity: Wishlist
Tags: patch

Hello,

the LeMaker Banana Pi is a small ARM development board based on
the Allwinner A20 SoC.  Several DDs have received one of these
boards at Debconf 14 and it would be really nice to have it
supported in Jessie's kernel 3.16.

Driver support for the board (UART, MMC, SATA, USB, Ethernet)
is already available in kernel 3.16, just the device-tree
information is missing.

A dts patchset for the board has been written by Hans de Goede
(see http://lists.infradead.org/pipermail/linux-arm-kernel/2014-October/292110.html)
and has been accepted upstream
(see http://lists.infradead.org/pipermail/linux-arm-kernel/2014-October/292431.html).

Attached is a patch against the current sid linux package SVN tree that
contains a "backport" of this patchset to kernel 3.16.  No content changes
were applied to the patchset, the patches were just refreshed to apply
cleanly against 3.16.  Included is also another dts patch from linux-next,
on which the patchset depends:

https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=0fc2b7af8cd5918c0101dfb178b5a3a4b021a50b

I would apprechiate very much if you could include this patch
into the linux 3.16.3-3 package for Jessie.

Regards,
Karsten
